Bram Gadeyne commented on TEIID-3511:
-------------------------------------

I see that the debug log changed the query a little. In the original query the BITAND part was like this:  BITAND(phr.status,2) <> 2

> I've added the debug plan for the query without the BITAND function and with the BITAND function as an attachment.
> The version without the BITAND function returns 438 rows and the version with BITAND function returns 833 rows. I can see however that rows are duplicated in this second result. I've checked this by executing the version with BITAND statement with select *.
