Hi,
I'm using Firebird 1.0 and i'm not getting the exception that should be
raised about the ambiguous fields.
I'm doing this

select *
from
MY_PROCEDURE(params) MP left outer join
TEST_TABLE T1 on MP.ID_TT = T1.ID_TT left outer join
TEST_TABLE T2 on T2.ID_TT_MASTER = T1.ID_TT
where
ID_STATUS = 2 <<=== Should raise an exception!?

The problem here is that the person who wrote this SQL didn't used the table
alias at the where, but it don't raised any exception.
