Advantage Error Guide
Problem: A reference to all columns in a table was not unique.
Solution: If multiple tables exist in the SQL statement, table aliases must be used to qualify the reference. For example, the following statement is not valid.
SELECT * FROM tbl1, tbl2 WHERE tbl1.id=tbl2.id AND CONTAINS( *, 'some words' )
It contains the * (all columns reference) in the CONTAINS scalar function, but it does not uniquely identify a table. It would need to be changed to something like the following:
SELECT * FROM tbl1, tbl2 WHERE tbl1.id=tbl2.id AND CONTAINS( tbl1.*, 'some words' )
