Comparing two databases: to start a comparison between
two databases click on the "Compare Databases" icon on the toolbar
(
) or the
"Compare Databases" item under the "Compare" menu. The Compare SQL
Server Databases dialog window that appears allows you to chose the
server(s) where the databases you wish to compare reside as well as
the databases themselves. If the databases you wish to compare are
not in the workspace already you can add them from this window.

Comparing select tables: if you wish to compare the
content of just some of the tables in the database or/and you need
to map tables that may have different names then click on the
"Compare Tables" icon on the toolbar (
) or the "Compare Tables" item under the "Compare"
menu. The Compare Tables dialog window that appears allows you to
map the tables you wish to compare one by one. After selecting the
databases where the tables to be mapped/compared reside, click on
the "Refresh" button right above the "All Tables" section - xSQL
Data Compare will populate the section with the complete list of
tables for each of the selected databases. To map the tables, click
on a table on the left, click on the corresponding table on the
right and then click the "Add to selection" button (">>") to
add the mapped pair of tables to the list of tables to be
compared.
