Subj:   INTERSECT ALL
 
From:   Michael Larkins

Hi Everyone:

I have noticed something different in the operation of SQL in V2R5 that seems rather odd and I am wondering if it is by design or a new bug.

Situation: I have a couple of tables that get joined together. When using an INTERSECT and INTERSECT ALL, I get the same answer set. This should not be the case due to the presence of a duplicate value. When doing this operation in previous releases, the duplicate came back in the answer set.

The verify that the data did not change, I did an INNER JOIN in V2R5 and the duplicate values are in the answer set.

Does anyone have any insight into this change?


Regards,

Mike
