Question

Now there is a nee

Answer 1

You can select from the different databases and use a cursor to loop the selected data. Within that cursor you can do some logic and update or delete from the target table.

Also SQL 2008 has a nice new MERGE statement which you can use to select/insert/update in one T-SQL query. http://technet.microsoft.com/en-us/library/bb510625%28v=sql.105%29.aspx

For more complex processes i use the first option. For more straight forward sync tasks i use the second option.

As an extra option there is also Server Integration Services (SSIS): http://blogs.msdn.com/b/jorgepc/archive/2010/12/07/synchronize-two-tables-using-sql-server-integration-services-ssis-part-i-of-ii.aspx
