Hi,

There is Oracle database bug 21387771 (Wrong result with subquery coalesce even with fix for bug 20871556), and we need to know Pega 7.2 product is using such kind of SQL or not by 11/8.
We understand there is Patch for this bug, but because of our client policy, we need to check that there is any impact for Pega 7.2 by this bug.

<<Subquery coalesce example>>
U1@ora> select * from test;
ID1 ID2
--------------- --------------------
1 1
U1@ora> select * from test2;
ID1 ID2
--------------- --------------------
1 2
U1@ora> select *
from test where id1 in (select id1 from test2) <-- This subquery is ignored.
or (id1, id2) in (select id1, id2 from test2);
0 rows.

Best Regards
