• When selecting text fields as key fields, the table comparison speed significantly increased.
• Added the possibility to save a template at any step of the wizard.
• Some other improvements and bugfixes.

 

Version 3.3.0.1

• Added the possibility to compare data using filters;
• Added the "Trim CHAR Fields" option, which allows to trim spaces in CHAR and NCHAR fields while comparing and synchronizing data;
• Added the Jump List with a list of templates for Windows 7;
• If while synchronizing data, the number of records returned from the server is smaller than the expected amount to be synchronized (i.e. because of triggers), now a warning is written to the log-file;
• Added the path parameter to the log file in the console version;
• Some other improvements and bugfixes.

 

Version 3.2.0.1

 

• RAM usage is optimized. Now the product consumes less memory when working with large tables.
• Added the new option - ‘Fill correspondence automatically’ for the console version. When enabled, new tables in the database (created after generating a template) are also synchronized and compared when databases are compared.
• When loading a template, the application can now ask for a password for the database if necessary.
• Added the possibility to encrypt passwords in the template.
• Sometimes table data were sorted incorrectly when displaying comparison results. Fixed now.
• When synchronizing databases located on one server, it is now possible to generate synchronization scripts containing table data.
• Added hints for options located on the application forms.
• Other minor improvements and bugfixes.

 

Version 3.1.0.1

 

• Added the ‘Disable foreign keys’ option on the Step 4 - Specifying data synchronization options which allows disabling foreign keys when inserting or modifying data.
• The ‘Before synchronization script’ and ‘After synchronization script’ on the Step 7 - Specifying additional scripts are now executed in the same connection context where the synchronization is performed.
• Script Editor. When saving and re-opening the editor, the character set chosen in the previous session is saved.
• If any database errors occur during the comparison process, the program informs about errors and offers to continue. The error texts are displayed as a hint in the Summary dialog.
• BLOB Editor. Added the possibility to view texts in Unicode.
• The process of selecting tables to compare has become more convenient.
• Added the possibility to disable the code folding in editors.
• Added the possibility to export comparison results of all tables at once.
• Added the possibility to use filters during the code completion.
• Some other small bugfixes and improvements.

 

Version 3.0.0.1

 

1. The comparison and synchronization algorithm is significantly improved and is optimized for working with large databases:

• The comparison speed is considerably increased, in some cases up to 5 times.
• The synchronization speed is increased, especially in cases when compared tables are located on one server.
• The amount of the consumed RAM is reduced, now it does not depend on the number of records in compared tables which allows avoiding the Out of Memory error.
• The speed of auto-fill in tables and fields is increased.

2. Added the possibility to synchronize BLOB fields in InterBase.
3. Added the option for viewing the Summary for the compared objects at the Step 3 - Browsing data comparison results.
4. Synchronization with deleting of records from tables containing foreign keys could result in an error. Fixed now.
5. Added the possibility to clear the template list.
6. Some other small bugfixes and improvements.
7. Windows NTLM Authentification feature added.

 

Version 2.3.0.1

 

• Added the Commit after synchronization option allowing to rollback all changes if an error occurs during the synchronization process.
• Added the possibility to define table synchronization order manually.
• Added the possibility to generate a summary report with table comparison results.
• It is now possible to sort and filter comparison results.
• Encrypted passwords within templates created with older versions of the utility could not be read properly. Fixed now.
• Some other small bugfixes and improvements.

 

Version 2.2.0.1

 

• Added tools for exporting comparison results to HTML and RTF
• Implemented support of Unicode data
• The new enhanced Script Editor

• Tables for which the set of key fields differs from primary key fields are synchronized significantly faster now
• Table lists are sorted by table name now
• The possibility to save synchronization logs to a file is implemented
• The number of DB connections coincides with the number of selected threads
• Other minor improvements and bug-fixes
