>>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.

>>>I need to check (from a VFP 9 application) if a table in the SQL Server DB exists. I found a pretty simple code in one of the online threads. The code is as follows:
>>>
>>>
>>>IF not (EXISTS (SELECT * 
>>>                 FROM INFORMATION_SCHEMA.TABLES 
>>>                 WHERE TABLE_SCHEMA = 'DBO' 
>>>                 AND  TABLE_NAME = 'MyTable'))
>>>BEGIN
>>>    print 'does not exists'
>>>END
>>>
>>>
>>>My question is about the Table_Schema. In general I still don't understand what is the SQL Schema. If I put the 'DBO' in the Table_Schema above, the code works; the table - if exists - is found. 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?
>>>
>>>TIA
