Key: TEIID-1545
URL: https://issues.jboss.org/browse/TEIID-1545
Project: Teiid
Issue Type: Bug
Components: Query Engine
Affects Versions: 7.3
Reporter: Mark Addleman
Assignee: Steven Hawkins
ORDER BY is not pushed down in the following query:
SELECT J0.APPNAME, B.\"SYSID\", B.\"USERID\",
(select count(*) from (select * from notes.RETRIEVE_NOTES where OBJECT_PKEY = B.USERID) as
foo) as C_notesForObject
FROM \"SECURITY.BASEUSER\" as B left join security.sysinfo J0 on
J0.sysid=B.sysid ORDER BY J0.APPNAME ASC
SECURITY comes from the DB2 translator
notes comes from a programmatic translator which does not support ORDER BY

Mark Addleman commented on TEIID-1545:
--------------------------------------
I would expect the ORDER BY to be pushed down to the DB2 translator since order is
irrelevant to the subselect.
Interestingly, if I change the WHERE clause in the subselect to compare against a constant
string, the ORDER BY *is* pushed down.

Steven Hawkins commented on TEIID-1545:
---------------------------------------
uncorrelated scalar subquery planning allows the expression to be seen as basically a
simple scalar. When correlated the planner leaves the projection in place above the
access to DB2 and does not consider pushing the order by.
The fix for TEIID-1529 could be expanded quite easily to handle this case as well.

Steven Hawkins resolved TEIID-1545.
-----------------------------------
Fix Version/s: 7.4
Resolution: Done
Expanded the logic from TEIID-1529 to compensate for unrelated order bys and to check for
the possibility for pushdown regardless of the use of a limit.

-----------------------------------------
Does this mean that the changes done for 1529 contains fixes for 1529 and 1545? Can I take
the patch from 1529 and apply it?
