Online Documentation for Data Comparer for SQL Server
Step 1 - Setting connection properties
At this step you should specify necessary settings to establish connection to SQL Server databases.
First select the connection type: local or remote.
Local connection is used to connect to SQL Server launched on the same machine where Data Comparer for SQL Server is running.
The Remote mode allows you to connect to SQL Server launched on another computer in the network.
By default the program uses local connection. It is indicated by switch Local selected. If you wish to establish remote connection, you should select the Remote switch. For remote connection you should also enter SQL Server host name in the Host field.
Please note that if Microsoft® SQL Server™ is installed as a named instance, you should specify 'Remote' as the connection type and enter the name of your machine and the instance name in the 'Host' field in the following format: computer_name\sqlserver_instance_name (e.g. "MYCOMPUTER\SQLEXPRESS").
Specify the type of SQL Server authentication to be used for the connection: SQL Server or Windows authentication. It is strongly recommended to avoid using SQL Server authentication with "sa" as the login.
If SQL Server has been selected as the authentication type, you should also provide authorization settings: Login and Password.
After that it is necessary to specify the database you are going to work with: type in its name in the Database field or use the ellipsis button to select one from the Select database list.
Please note that you need to have sufficient privileges to be able to write to the destination database on SQL Server.
Repeat the steps above for the target SQL Server connection or just check the Both databases on the same server option for comparing data from databases located on the same server.
