Answer 1

Hi
Sorry for not giving more details... I meant something like this:
select distinct reqnum
from tablea -- your data model A table
union
select distinct reqnum
from tableb -- your data model B table
The "union" is only required if there are reqnums that exist in tableb but not in tablea. It it is not the case, you can use just:
select distinct reqnum
from tablea
