Question/answer list
Product questions
Q: What is EMS SQL Management Studio?
A: EMS SQL Management Studio is a complete solution for database administration and development. SQL Studio is an integrated suite of powerful database management tools united in one easy-to-use work environment. Developers will appreciate its ability to create/edit/drop any database objects and will find metadata and data comparison, data export/import and test data generation tools extremely helpful. Database migration, backup and restore tools will be of great help to DBAs. The Scheduler will automate a sizeable part of DBA's work.
Q: SQL Studio embraces a variety of capabilities, but will I need them all? Is there a simpler product?
A: This question naturally comes if you are new to database administration and development. It might not be immediately obvious why you would need so many different tools. We would like to point out that your experience will build up day in and day out, you will face new, more complicated tasks and you will need more tools to solve them. SQL Studio embraces ALL must-have tools for DBAs and developers. And it will be in line with your growing expertise! Besides, once you familiarize yourself with SQL Studio tools, you will be able to find the simplest, most suitable and reliable solutions to your tasks! We do realize that our product is used not only by experts, that is why we included plenty of Wizards that will make the job easy and enjoyable even for a newbie. The Studio interface is designed so that the component tools are called only when needed, not to hinder your work. Our experience shows that the majority of our customers get used to our products really fast, and we have never received any downgrade requests.
Q: What do I need to start working with SQL Studio?
A: In order to start working with SQL Studio, you need to download the installation package from the download page available at our site. Then run the installation file on a MS Windows workstation (see System requirements for details). When the installation is finished, the program is ready to be used in the trial mode. You can evaluate the trial version for 30 days. This is the time for you to make a purchasing decision. You can purchase the Studio here. After the payment is complete, your will receive your registration information via e-mail (see How to register SQL Studio for details)
Q: Many utilities that are included in SQL Studio are also offered as stand-alone products. What are the advantages of purchasing them within the Studio?
A: Indeed, in order to perform some simple task, you can purchase a separate EMS utility or a few of them. Yet, if you purchase these utilities within the Studio, you receive additional functionalities. First of all, you will be able to launch the Studio components from Task Scheduler. That is, you can set the order to run the tools in, set the parameters to be used, the time and/or time intervals for the task to be performed and go to play a bowling game :) Task Scheduler will fulfill all your tasks, save the logs for the performed operations and will notify you by e-mail about the successful/unsuccessful task completion. Task Scheduler will help you to really automate the majority of your DB service tasks. Secondly, you will be able to store all registered Databases in one repository. Thus, you will need to register your data source once and will be able to use it in all Studio tools. This will save your time and reduce an error chance to the minimum. The third equally important benefit is the pricing. When purchasing the tools within SQL Studio, you pay a lot less, compared to purchasing them as separate products. You will receive up to 40% off the original price!
DB registration and connection
Q: Can I work with several databases simultaneously?
A: Yes, SQL Studio allows you to work with an unlimited number of databases at the same time. You can also operate any number of databases via SSH tunneling. Once the database is registered at the database source repository correctly, you are ready to use it.
Q: I use Windows OS, but my remote Interbase/Firebird server is running on Linux OS. Will I be able to use SQL Studio to work with this server?
A: Yes, that is possible. It does not matter what OS the database server is running under, SQL Studio works only in the Windows environment (see System requirements for details).
Q: Why does SQL Studio use a single registered database repository?
A: The single registered database repository allows one database to be accessed with all SQL Studio tools. If you purchased our product suites (bundles) previously, you had to enter the database information in each tool you used. That eventually led to massive time wasting and typing errors. Now the problem is solved in the Studio with the help of the single registered database repository.
A: SSH (Secure Shell Host) protocol is used to heighten the computer security when working with Unix systems in Internet. SSH uses several encryption algorithms of different reliability. The spread of SSH is also concerned with the fact that a number of Linux-like OS's (for example, FreeBSD) include SSH server in their standard integration. To get more information about this issue, please, visit https://www.openssh.org.
SSH tunneling feature of SQL Manager is a means for secure connection to Interbase/Firebird servers when working over insecure connection channels. You can also use SSH tunnel to get access to the remote Interbase/Firebird servers, when the default port is closed for external connections due to some reasons. Connection over SSH tunnel works in the following way. First, a connection is established, and authentication between SSH client built in SQL Manager and the remote Interbase/Firebird server is performed. Then all in- and outgoing information between the program and Interbase/Firebird server is transmitted through SSH server with the help of the communication port (usually it is 22), and SSH server transfers this information directly to Interbase/Firebird server.
To register a database to which one connects through SSH tunnel, you should set the following parameters in Register Database Wizard of SQL Manager for InterBase/Firebird:
'Host' is a host where Interbase/Firebird server is located from the point of view of SSH server. If SSH and Interbase/Firebirdserver are on the same machine, it is equal to SSH Host, or may be 'localhost'.
'Port' is a port of Interbase/Firebird server on the remote host.
'User name' is a Interbase/Firebird user name.
'Password' is the password of the Interbase/Firebird user. Please note that Interbase/Firebird host name should be set relatively to the SSH server in this case. For example, if both Interbase/Firebird and SSH server are located on the same computer, you should specify 'localhost' as Host name instead of the server's external host name or IP address.
Check "Use tunneling" and "SSH tunneling".
'SSH host name' is the host where SSH server is activated.
'SSH port' is the port where SSH server is activated.
'SSH user name' is a user on the Linux/Windows machine (it is a Linux/Windows user, not a user of Interbase/Firebird server)
'SSH password' is the Linux/Windows user password.
If necessary, check 'Use Private Key for authentication'.
Q: I work behind a firewall (router). Can I use SQL Studio to manage a remote Interbase/Firebird server?
A: If, due to the security policy accepted in your corporate network or by your host provider, you cannot connect to your Interbase/Firebird server directly through TCP/IP (for example, a firewall prevents this), you can use SSH tunneling feature of SQL Manager to fulfill your task.
Q: I cannot connect to the local Interbase/Firebird server. Why?
A: There are several reasons why you cannot connect to the local database. If during connection you get error "Connection failed. Server is stopped or unproper client library is used to establish connection to the server. SQLCode: -904 IB Error Number: 335544375", then you should check if the port or service used for server connection is set correctly, and whether the local server is running. To check if the service is launched, open Control Panel -> Administrative Tools -> Services and find service InterBase Guardian (if you use InterBase) or Firebird Guardian (if you use Firebird). In case you find it, run it using the Start item available in the context menu. If you cannot launch this service, then probably your server is installed incorrectly and you need to reinstall it.
Another possible reason for this error is that the client library version does not coincide with the server version.
If you get the error like "Your user name and password are not defined. Ask your database administrator to set up a Firebird login.
SQL Code: -902 IB Error Number: 335544472" then the reason for this is that the registration data you enter are absent in your server security database. You should register the user with the proper login and password on your server.
Q: I cannot connect to a remote Interbase/Firebird server. Why?
A: There could be several possible reasons that prevent you from successful connection to the remote database.
If the error message says, "Connection failed. Server is stopped or unproper client library is used to establish connection to the server. SQLCode: -904 IB Error Number: 335544375", then probably you should check the correctness of port and host name you have entered and also if the remote server is running. It often happens that the port through which the connection is set with InterBase/Firebird server (normally, it is 3050) is closed for security reasons by a local firewall, corporate firewall or remote server firewall. Please check this with your system administrator or ISP. In order to avoid this limitation, you can use SSH tunneling.
Q: I can't configure the connection to Interbase/Firebird server by SSH. Which values do I need to input on the SSH page of the Database Registration Info dialog?
A: To setup SSH connection correctly, input the following values into the corresponding fields within the SSH Tunneling section of the Database Registration Info dialog of SQL Manager for InterBase/Firebird:
'SSH host name' is the host where SSH server is activated.
'SSH port' is the port where SSH server is activated.
'SSH user name' is a user on the Linux/Windows machine (it is a Linux/Windows user, not a user of Interbase/Firebird server)
'SSH password' is the Linux/Windows user password.
If necessary, check 'Use Private Key for authentication'.
Q: When I try to register a database, I get the following message: "Your user name and password are not defined". Why does it happen?
A: This is caused by the fact that the registration data you enter are absent in the security database of your server. You should register the user with the proper login and password on your server.
Q: I receive the following message: "Database ... shutdown". What am I doing wrong?
A: This message indicates that your database is used in a single-user mode and it cannot be accessed only by the creator and SYSDBA. To switch to the multi-user mode, you need to publish your database.
Q: I've registered the DB, but on attempt to open it the "client library was not found" message appears.
A: You receive this error message because the program can not find the client library which is essential to work with the server. You should check if the paths you defined in the server registration information are correct, and whether the client library file is available. If this file is missing, please, install the client software from the server distribution kit.
Objects manipulation
Q: Which database objects will be accessible through SQL Studio?
A: You can work with any objects in Interbase/Firebird databases such as tables, fields, indices, views, stored procedures, functions, triggers, etc.
Q: I have over a million records in the table, yet the data grid displays only 1,000 of them. What is the problem?
A: Please select the "Select all records from a table" option within the Grid section of Environment Options dialog in SQL Manager for InterBase/Firebird. Note that fetching all records from a table may require considerable time.
Q: How can I speed up my work with large tables?
A: For your convenience and to speed up your work, the Data Grid allows customizing a number of data display parameters. Here are the most important of them (accessible through the Grid | Data Options section of the Environment Options dialog):
- Limit options in table and view editors. The 'Select all records of a table' option will enable you to see all table records without extra references to the server, yet in case of large tables or low speed connection channel the data may be fetched with huge delays and the incoming traffic might grow considerably. This mode is recommended when working with local databases or in a private network. The 'Select only' mode restricts the maximum number of records returned after the query. A man cannot process a massive amount of information at once. Hence, we came up with this mode. This mode speeds up table data viewing considerably, prevents hanging and connection timeout. It is recommended to work with large tables, in case of low speed connection channels and when the traffic volume is of importance. This is the default mode. When in this mode, enabling the 'Use SQL sorting in data view' and 'Use SQL filter in data view' options comes really helpful.
- Default Grid Mode. This option defines whether the requested rows will be loaded in the Grid all at once ('Load all rows'), or in parts ('Load visible rows') as the user scrolls down table data. The first mode increases the query opening time, but speeds up scrolling. In the second mode the query opens very fast, but there might be delays when navigating the grid.
- Use SQL sorting in data view. With this option enabled, when the user sets data sorting, a new request is sent to the server, and the result is shown anew in the Grid. Enabling this option is very helpful with the 'Select only' mode enabled, but it increases the traffic. When this option is disabled, sorting is made on the client computer without any references to the server but only loaded data are sorted. That is, if you set 'Select only 1,000 records', then only these records will be sorted.
- Use SQL filter in data view. With this option enabled, the data will be sorted on the server to which a new request is sent, and the result will be shown anew in the Grid. Enabling this option is also helpful when the 'Select only' mode is on, but it increases the traffic. When this option is disabled, the filtering is made on the client computer without any references to the server but only loaded data are filtered. That is, if you set 'Select only 1,000 records', then only these records will be filtered.
We recommend that you set the following option values to achieve maximum efficiency when working with large tables:
- Select only – ON
- Load visible rows – ON
- Use SQL sorting in data view – ON
- Use SQL filter in data view – ON
Q: Which operations can I perform over database objects?
A: You can create new objects, drop and edit the existing ones. You can also copy the objects from/to databases located on one or different hosts.
Q: When creating a table like 'TestTable', it will get stored as 'TESTTABLE'. How can I get objects stored as I create them using SQL Manager?
A: Please try to deselect the "Always capitalize database objects names" option within the Options section of the Database Registration Info dialog.
Q: How can I customize data formats in a grid?
A: You can customize all display formats: integer, float, date, time and datetime using the Color & Formats page of the Environment Options dialog in SQL Manager for InterBase/Firebird.
Q: My database uses a "Greek" codepage. In data grid view all information is displayed at "??????". What is wrong?
A: You need to set up the "Client charset" parameters to make the server return the information to the client (our program) in the needed code page. Please, open the Database Registration Info window and specify the "Client Charset" option to '"greek (ISO 8859-7 Greek)".
A: The DDL tabs of the SQL Studio editors are read-only. To modify an object, you can copy the text to the clipboard and modify it using SQL Editor or SQL Script.
Query
Q: I'm new to SQL, and I can hardly compose the SQL statements by hand. Does SQL Studio have a visual query builder like in MS Access?
A: Yes, SQL Studio offers a powerful Query Builder that allows newbies to build complex queries visually, and drastically saves time for advanced users. All you need to do is to specify the tables that will be used in the query, their relations and the query conditions for the data you want to get. Visual Query Builder will generate the text of the query for you. You will only need to run it. You can see the result of your query and make corrections if necessary. The changes can be made from the visual builder or from the text editor. As changes made in visual query builder, the text editor will display them too and vice versa.
Q: Can I use the visual query builder in STUDIO to build the complex queries with unions and subqueries?
A: Yes, visual Query Builder can build complex queries including UNION operator and subqueries.
Q: Can I save a created query for future use?
A: Yes, of course. SQL Studio can save the needed query in the following ways:
1. ALL executed queries are automatically saved in the History. You can view the History and execute or edit any query you need.
2. You can add the frequently used queries to the list of Favorite queries.
3. You can save any query as an SQL-script into a file on your hard drive and load it when needed, or execute it with a command line SQL script tool.
4. You can save your query as a chart. In this case after the query is loaded into SQL Studio, the the chart will be displayed the way it has been created. SQL Studio allows you to save the query chart as a bitmap image.
Q: Can I run a query from the command line?
A: Yes, SQL Studio offers SQL Script tool for this purpose. It can also run a script from a file saved on your hard drive. This feature allows you to create queries and schedule their execution using Task Scheduler. Task Scheduler allows you to run your query when you need it and notifies you when done.
Q: Can I save a query result into a CSV or an XLS file?
A: Yes, SQL Studio has a powerful tool for exporting your data (including the query results). You can export the result dataset to MS Access, MS Word, CVS, XLS, HTML, RTF, DBF, XML and other formats. To ease the exporting procedure, Export Data tools are implemented.
Reports management
A: To create a report, you can use the Create Report Wizard or the Report Designer tool in SQL Manager for InterBase/Firebird. To create a report based on a query, see Q. How can I create a report based on a query?
Q: How can I create a report based on a query?
A: To create a report based on a query, you can use the Create Report Wizard in SQL Manager for InterBase/Firebird. You need to choose Master Data band on the second step of the wizard, double-click on it or click the Edit button and specify the query for your report. After that you need to set options in other steps of the wizard and press Finish.
Q: Can I save my report as HTML, Excel or Word?
A: Yes, open the report by double-clicking on it in the DB Explorer of SQL Manager and select the 'Save report as' item in the Navigation bar or toolbar, and specify the format you want to save to in the "Save as type" field.
Data manipulation
Q: What is the difference between the Export/Import functions in SQL Studio and stand-alone SQL Manager?
A: The Data Export/Import tools of SQL Studio include some additional features which are not available in SQL Manager for InterBase/Firebird, such as:
- export/import data from/to several tables simultaneously;
- export/import data from/to tables selected from different databases on one host;
- a command-line utility to export/import data using the configuration file with all the export/import options;
- a single registered database repository.
Q: I need to import data from a CSV file. How can I do it with the help of SQL Studio?
A: You can use Import Data Wizard for this purpose. It will help you to set all the necessary import parameters. Moreover, you can save these settings as a template and use them in the future. Besides, you can also import from MS Excel, MS Access, DBF, XML, TXT and other formats.
Q: How can I change the default directory where exported data will be saved?
A: Follow the steps below to change the default directory:
1. Right-click the database alias in DB Explorer and select the 'Database Registration Info...' context menu item (you can also find this item in the 'Database' main menu) to open the Database Registration Info dialog.
2. Proceed to the Directories section within the dialog.
3. Set the 'Default directory for Export Data'.
Q: For which purpose are the console versions of the utilities for manipulating data included in SQL Studio?
A: The main function of the console versions of SQL Studio tools is execution of some service operations with the database without a user involved. All console tools support configuration files (templates) that are created in the corresponding GUI versions. The template file contains all information necessary for working with the console version. With the help of the console version and a template file you can create a task in the Task Planner and set the necessary time and/or period for execution. Of course, you can use the console versions of SQL Studio tools in your own automatic applications.
Q: I have a database in MS Access. I want to migrate to the remote Interbase/Firebird database. How can I do it with the help of SQL Studio?
A: You can use Data Pump for InterBase/Firebird for this purpose. To launch Data Pump from SQL Studio, select the Data Manipulation tab and click on Data Pump for InterBase/Firebird, or select Start -> Programs -> EMS -> SQL Studio for Interbase/Firebird -> Data Pump for InterBase/Firebird. We recommend that you use Microsoft Jet 4.0 OLE DB Provider to connect to your MS Access database.
Q: I have a ODBC data source. Can I migrate from it to Interbase/Firebird?
A: ODBC (Open Database Connectivity) is an open standard interface to access databases developed by Microsoft. Most database management systems have their own ODBC driver or the one produced by other software developers.
To migrate from a ODBC data source, you need to use Data Pump for InterBase/Firebird. To launch Data Pump from SQL Studio, select the Data Manipulation tab and click on Data Pump for InterBase/Firebird, or select Start -> Programs -> EMS -> SQL Studio for Interbase/Firebird -> Data Pump for InterBase/Firebird. When working with the utility, you should use OLE DB Provider for ODBC Drivers to connect to your ODBC data source.
Q: From which databases can I migrate to my database server with the help of SQL Studio?
A: With the help of Data Pump for InterBase/Firebird you can migrate from any databases to which you can connect using OLE DB Provider (for example SQL Server, Oracle, MS Access, DB2, etc.) and ODBC Driver (MySQL, PostgreSQL, InterBase, Firebird, dBase files, etc.)
Q: I am working on an application. The database structure is already created. How can SQL Studio help me to fill the database with test data?
A: SQL Studio has a powerful instrument for generating test data - Data Generator for InterBase/Firebird. The wizard will help you to set such parameters as the amount of records to be generated, range value for each field, the quantity of lines with NULL value and others. Data Generator performs various algorithms including random or increment data generation as well as the one according to the given list of values and many others. And of course, it is possible to save all these settings as a template for future use.
Q: My database contains many relations between tables and other constraints. Will SQL Studio consider them while generating test data?
A: Yes, of course. When generating test data, the Data Generator module of SQL Studio takes into consideration all relations and restrictions that already exist in your database.
Data analysis
Q: I need to find the differences in the metadata of two databases and then synchronize them. How can SQL Studio help me with this task?
A: There is a tool specially designed for this purpose - DB Comparer for InterBase/Firebird available in the Data Analysis group of SQL Studio. Its interface is simple and user-friendly, but the results of its work are quite impressive! You only need to choose two databases to compare metadata and set some additional parameters, such as database objects to compare, direction of synchronization and others. The result of DB Comparer's work will be a list of differences in the metadata of these two databases and a script, with the help of which you can synchronize the databases. Besides, you can synchronize each difference separately, using only the needed changes in the required order. Do you remember how much time you spent searching for the single field added to the table two months ago? :)
Q: I need to find the differences in the data between the existing database and its yesterday's backup. What should I do?
A: There is a tool specially designed for this purpose - Data Comparer for InterBase/Firebird available in the Data Analysis group of SQL Studio. You should specify the existing working database as a source database. Then specify the database of the yesterday's backup as a target database (you should first restore it on any available Interbase/Firebird server). Now choose data in which tables you would like to compare and follow the other steps of the wizard. Mind, that Data Comparer allows comparing data in tables with non-identical metadata. After the comparison is complete you will see the list of differences between your databases and will be asked if you would like to synchronize data from source to target or from target to source. You can save SQL script that performs synchronization in a separate file and run it later with the help of SQL Script tool (probably using the Task Planer).
Q: Can I start synchronization of metadata or data from the command line?
A: Yes, for this purpose you can use the console versions of our utilities - DB Comparer Console Application and Data Comparer Console Application. All console tools support configuration files (templates) that are created in GUI versions of the programs. The template file contains all the information necessary for working with the console tool. With the help of the console version and the template file you can easily perform synchronization from a command line without setting a great number of parameters manually.
Q: Can SQL Studio synchronize my database with a database of another DBMS?
A: This feature is not supported by our utilities as they allow synchronizing data and metadata only between one database engine, that is between Interbase/Firebird and Interbase/Firebird.
Backup/Restore
Q: What Backup capabilities does SQL Studio provide?
A: SQL Studio offers several methods of creating database backups.
- Using Backup Database service
This method is very fast and reliable. On its application you do not need to shutdown your database, i.e. other users can continue working with it. Besides, this method allows you to receive database backup files in a portable format, which enables you to restore these databases on the servers with different ODS (on-disk-structure), and this is crucial to perform database migration between servers. It should be noted that this backup method allows one to change the database owner, which is important when changing the server security structure. While using the Backup Database Service table indices are recomputed and database garbage is collected, which regulates database size and improves its overall performance. The disadvantages of the method are that you cannot choose database objects that need to be backed up; and the back up file is not saved on the local workstation when copying a database located on remote server.
To call this service, open the Database Management tab in SQL Studio and select the Backup Database item of the Services group.
To call this service from SQL Manager for InterBase/Firebird, use the Services | Backup Database... main menu item.
In order to restore the databases from the backup file created with this method, use the Restore Database service. This service enables you to restore your database to the file of the existing database or create a new database on the basis of the existing backup copy. If the database is restored in an already existing database, the structure of the backup copy may be restored partially; as a result, the existing database structure will be lost, that is why we do not recommend to use this option.
To call this service, open the Database Management tab in SQL Studio and select the Restore Database item of the Services group.
To call this service from SQL Manager for InterBase/Firebird, use the Services | Restore Database... main menu item.
- Using DB Extract for InterBase/Firebird or Extract Database Wizard of SQL Manager for InterBase/Firebird
Both tools create backup copies of the whole database or of user-specified objects in the form of SQL script. The generated script contains Data Definition Statements and Insert Data commands. The main advantages of this method are the complete or partial backup of the database structure and data and flexible customization possibility. However, with this method creating back up copies of large databases is time and traffic consuming.
To call DB Extract, open the Data Analysis tab in SQL Studio and select DB Extract for InterBase/Firebird.
To call Extract Database Wizard, open SQL Manager for InterBase/Firebird and select the Tools | Extract Database main menu item.
In order to restore the database from the script, you need to run this script on the Interbase/Firebird server. Please use SQL Script available in SQL Studio or SQL Script tool of SQL Manager for InterBase/Firebird.
- Using Data Export for InterBase/Firebird
This method can be used to back up data from any tables. Please use it if you need to save only data but not the database structure. We would recommend to use CSV format to back up data.
To call Data Export, open the Data Manipulation tab in SQL Studio and select Data Export for InterBase/Firebird.
To call Data Export Wizard from SQL Manager for InterBase/Firebird, open your table in Table Editor, proceed to the Data tab and select 'Export Data'.
In order to restore data from the file created with this method, you can use Data Import for InterBase/Firebird or Data Import Wizard of SQL Manager for InterBase/Firebird.
To learn about the differences between Data Import for InterBase/Firebird and Data Import Wizard of SQL Manager for InterBase/Firebird, see Q. What is the difference between...
Q: Is it possible to restore the backup on one server while it was created on another one?
A: Please observe the following cases:
- The backup file created with Backup Database service can be restored on another server if its version is the same or higher compared to the server version that performed the backup. Besides, the server type matters when restoring the backup copy – it is not recommended to restore a Firebird backup file on InterBase server and vice versa. These restrictions are related to possible differences in SQL syntax used to create database objects (DDL) and to work with data (DML) in different servers and also to the absence/presence of certain types of data in different type servers and different server versions. These restrictions are not stringent and it is possible that the backup copy will be restored even if you neglect them, yet we can not guarantee that such database will be fully operational.
- The restoration of the backup copy created with DB Extract for InterBase/Firebird or Extract Database Wizard of SQL Manager for InterBase/Firebird is subject to the same restrictions stated in point 1.
- The Data backed up with Data Export for InterBase/Firebird or Export Data Wizard of SQL Manager for InterBase/Firebird can be restored to a table on any version of Interbase/Firebird server.
Q: Where can the backup file be located?
A: A backup created by Backup Database Service can be placed only in the local directory on the server.
Q: What is the difference between Extract and Backup functions in SQL Studio?
A: Backup Database service creates backups of all objects of the selected database, as well as table data, according to the defined path that can be only a local directory on the server.
DB Extract for InterBase/Firebird or Extract Database Wizard of SQL Manager for InterBase/Firebird creates backups of databases or user-defined objects in a form of SQL script. Thus, Backup Database service uses Interbase/Firebird capabilities to create database backups, it is highly reliable, but it cannot place backup files in any client directory. It is recommended to use this method for backing up a whole database. The main advantages of creating backups with the help of DB Extract for InterBase/Firebird are that you can save structure and data of some specific database objects or schemes and that backup copy is created on the client side. The weak point of this method is much time and traffic that are required for creating backups of large databases.
Templates management
Q: What are the templates used, for example, in export/import? What are they for?
A: Templates in SQL Studio are intended for storage of the parameters required for running SQL Studio tools. Using the templates you will be able to repeatedly perform one and the same operation without a need to enter 10-20 wizard parameters each time. The parameters stored in a template can be easily modified, or you can create a new template based on the existing one.
Q: Where are SQL Studio templates located?
A: A template is a file that can store necessary parameters in certain format. Template files can be located anywhere on your PC. To simplify the task of template storage and search, SQL Studio provides Template Manager. The Manager allows you to register the necessary templates in SQL Studio and not to worry anymore about the place where you saved them to. When you create a new template in SQL Studio the Template Manager automatically remembers its location on the disk. All the registered templates are grouped by the tools they are intended for and will be at your disposal any time. To run a tool with the selected template, you will just need to double-click the template.
Q: If I delete a template from the list in SQL Studio, will it be deleted from the hard disk?
A: Template Manager allows you to perform both operations: you can either delete a template from the registered template list only, or delete it also from the hard disk.
Q: How can I create a new template for Import?
A: To create a template for the Import tool, you should run the Import tool (Run | Data Import for InterBase/Firebird). Then you will need to fill in all the necessary import parameters using the Next button. At the last wizard step you should define the name and location of the newly created template using the Tools | Save Template menu item. See Using templates for more information.
Scheduler
Q: I need to perform certain operations on my database (export from one database, import of those data to another one, backup of both databases) outside business hours (at night). Does SQL Studio provide any solution for this?
A: Yes, sure. The Studio Scheduler is intended for such situations. The Scheduler can run for execution of the previously created tasks. You can set the time and periodicity for the task execution. Each Task can include an unlimited number of Steps (elementary operations). A Task must include at least one step. In your case you should perform the following:
1. Create new Task
2. Create steps in the Task (Export, Import, etc.). When creating these steps, you will need to indicate in what template files the necessary tool parameters are saved.
3. Create a Scheduled Task in the Scheduler that will use the Task you have just created (1).
Q: How do I configure a task so that I receive an e-mail notification at the defined address in case of the task failure?
A: In the Task editor there is a tab called Alerts. By switching to this Tab you will be able to define the most suitable notification method to be informed of successful task execution and/or of the task failure. The current version of SQL Studio supports the following notification types: Net Send, System App Log (WIN), e-mail.
Q: Can the task process be changed depending on the results of the task steps?
A: Yes. When creating/editing each Task Step, you can define which step should go next. Moreover, for each of the three processed events (successful step termination, erroneous step termination, step termination by time-out) you can indicate a separate variant of the next Task operations.
Q: How can I view the information on the performed tasks?
A: All the information on the Task execution is fixed in the log. In the log you can find not only the information on the Task, but also on the Steps it includes. Moreover, you can view the log file of the attachment executed at a certain step. It is very convenient while analyzing the reasons of the Task/Step failure. The powerful log filters will allow you to display only selected records.
Q: What will happen if during a task execution the running application cannot terminate (critical error, does not respond)? Will the task execution stop?
A: To resolve such conflicts, in every Task Step you can define its time-out. If a Step is being executed longer than it is defined in the time-out, the Step will terminate with the "by time-out" event, and the Task execution goes on according to the algorithm you set.
Q: What do I need to work with Task Scheduler?
A: To work with Task Scheduler, you need to run the Studio Agent (a shortcut in the task bar). Also, your computer should be running during all the time while the tasks will be run.
Q: What will happen if, after running the computer, Task Scheduler finds the tasks that should have been executed in the past, but it has not happened?
A: Those tasks will not be performed.
Logs management
Q: It is important for me to get the information from log files of applications executed by the Task Scheduler? Does SQL Studio save these log files?
A: Yes, SQL Studio has a convenient tool to work with log files. While creating a Step in the Task, you can specify the location of the log file of the application to be executed. When choosing the tools from SQL Studio, the location of the log file is filled automatically. Log files of the performed steps are saved in the internal SQL Studio database and are available within the Tasks | Logs menu.
Q: The external application that is executed in one of the tasks does not have a log file, but only a screen log. How can I save the data from the screen?
A: If a utility does not have a log file, and the log information is only displayed on the screen (in text mode), then SQL Studio can save these data as a log. To do so, please check the "Save screen to log" box when creating a task.
Q: How long are log files stored in SQL Studio?
A: Log files are stored in SQL Studio during an unlimited period. You can delete the unnecessary log files manually in SQL Studio (within the Logs tab).
Localization
Q: What interface localizations are available in SQL Studio?
A: The current version of SQL Studio supports the following interface localizations: English, German, French and Russian.
