[JBoss JIRA] (TEIID-2337) Source Hints documenation states source hints can be used in user and transformation queries
by Johnathon Lee (JIRA)
[ https://issues.jboss.org/browse/TEIID-2337?page=com.atlassian.jira.plugin... ]
Johnathon Lee resolved TEIID-2337.
----------------------------------
Resolution: Rejected
The SQuirreL SQL client was stripping the HINT. After changing client settings this worked for passing a HINT in a client SQL statement.

[JBoss JIRA] (TEIID-2341) Better handling for outer join restriction pushdown
by Steven Hawkins (JIRA)
Steven Hawkins created TEIID-2341:
-------------------------------------
Summary: Better handling for outer join restriction pushdown
Key: TEIID-2341
URL: https://issues.jboss.org/browse/TEIID-2341
Project: Teiid
Issue Type: Enhancement
Components: Query Engine
Affects Versions: 8.2
Reporter: Steven Hawkins
Assignee: Steven Hawkins
Fix For: 8.3
For some sources (such as salesforce) they are restricted to outer joins. Queries entered as inner joins or are effectively the same using an outer join should still be pushed to the source.
It would also be good to have a hint to simply preserve the join structure as entered by the user to give them more control over the processing.

[JBoss JIRA] (TEIID-2331) TEIID30019 Unexpected exception for request kfhsdoaNXYfM.1: java.lang.NullPointerException
by Steven Hawkins (JIRA)
[ https://issues.jboss.org/browse/TEIID-2331?page=com.atlassian.jira.plugin... ]
Steven Hawkins commented on TEIID-2331:
---------------------------------------
An NPE should not be possible on line 734. The block is synchronized and we test if the receiver is null (line 659) before proceeding with the result logic.
The all null row is a construct added (in TEIID-2257, which must have been somewhat ported to your version) for the continuous logic to delineate when a result iteration is ending.
It would probably be best to have this reproduced on a non-patched version.

Steve we are running into NPE in requestWorkItem.
org.teiid.dqp.internal.process.RequestWorkItem.sendResultsIfNeeded(TupleBatch) - line 753 receiver.receiveResults(response);
receiver is null due to which we are hitting NPE.
As per teiid 8.1 branch it seems to be line 734. http://anonsvn.jboss.org/repos/teiid/branches/8.1.x/engine/src/main/java/...
One mroe thing that i observed is batch should contain only 3 rows but there were 4 rows with its last thing as null.
