Hi,

dbo.is default owner/schema for MSSQL and each database.
The answer for your question is: Yes, because you can have in database two tables: dbo.anytable and my.anytable with different structure. "my" is next schema.

But could there be a case - in the customer SQL Server database - that I need to enter something different than 'DBO'? Or, to be safe, should I drop the TABLE_SCHEMA from the WHERE completely?
