You need to specify the table with the fully qualified format:
SERVER.DATABASE.OWNER.TABLE or whatever format the ODBC driver is expecting.
The DATABASE portion is what they refer to as CATALOG or SCHEMA. I usually end
up trying any combination I can think of until I reach the right one. I can
tell you it is expecting three dots, and it can accept blanks in between if it
can use a default. For example, in MS SQL Server, owner defaults to 'dbo' if
left blank.

The docs in MS SQL Server are not too clear on this subject. Good luck.

BTW, you will want to alias the fully qualified name in any queries since you
can't use it to specify a field. SERVER.DATABASE.OWNER.TABLE.FIELD is not
valid. It's SELECT T.FIELD FROM SERVER.DATABASE.OWNER.TABLE T WHERE...
