Online Documentation for SQL Query for SQL Server
Setting connection properties
Enter the necessary settings to establish connection to SQL Server.
Host name
Type in, or use the drop-down list to specify the host name of the SQL Server server.
Please note that if SQL Server is installed as a named instance, you should enter the name of your machine and the instance name in the Host name field in the following format: computer_name\sqlserver_instance_name (e.g. "MYCOMPUTER\SQLEXPRESS").
Authentication Type
Specify the type of the database server authentication to be used for the connection: SQL Server Authentication or Windows Authentication. It is strongly recommended to avoid using SQL Server authentication with "sa" as the login.
Afterwards you should specify authorization settings: User name and Password.
Click the Advanced button to view/edit additional parameters for connection using SQL Server Client Network Utility.
Register a single database
Check this option if you wish to register one database at the host.
If the Register a single database option has been unchecked, you should also specify the databases you wish to be registered at the host. To select a database, you need to move it from the Available databases list to the Selected databases list. Use the buttons or drag-and-drop operations to move the databases from one list to another.
Click the Next button to proceed to the Setting registration options step of the wizard.
