• How can I compare tables in two different databases using SQL?

  - by chama

  I'm trying to compare the schemas of two tables that exist in different databases. So far, I have this query SELECT * FROM sys.columns WHERE object_id = OBJECT_ID('table1') The only thing is that I don't know how to use the sys.columns to reference a database other than the one that the query is connected to. I tried this SELECT * FROM db.sys.columns WHERE object_id = OBJECT_ID('table1') but it didn't find anything. I'm using SQL Server 2005 Any suggestions? thanks!
