Robert DeVito created DRILL-4900:
------------------------------------
Summary: Query across Sybase and Oracle plugins is dropping WHERE
clause
Key: DRILL-4900
URL: https://issues.apache.org/jira/browse/DRILL-4900
Project: Apache Drill
Issue Type: Bug
Components: Client - JDBC, Storage - JDBC
Affects Versions: 1.6.0
Environment: Windows client. Sybase and Oracle hosts on unix
Reporter: Robert DeVito
Have tried several approaches of joining simple queries with Oracle and Sybase.
In all cases, we have sufficient WHERE clause on each side to really limit
data. Each time, the Drill execution plan skips the WHERE clause on one side.
ex:
select a.f, b.b
from
(
select * from pl1.`owner`.`dbo`.`VIEW1` d
where d.fid = '0000300769'
and d.PDate = ('2013-10-31')
) a,
(
select * from pl2.owner.VIEW2 v
where v.f = '0000300769'
and v.d = 'M'
and v.b IN
('UK221','UK222','UK223','UK224','UK225','UK227','08843','BU5552','BU5543','BU5544')
and v.dk = '20131031'
) b
where a.f = b.f
and a.S = b.S
Please ignore the obfuscated column names. Syntax is valid, but Drill keeps
sending selects with no WHERE clause for one subquery or the other. Can't
understand why, or how to control it. This is a make or break for us.
Thanks
