[teiid-issues] [JBoss JIRA] Commented: (TEIID-1144) PostgreSQL (simple capabilities) returning an unexpected number of rows

Tue Jul 6 17:01:46 EDT 2010

    [ https://jira.jboss.org/browse/TEIID-1144?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12538058#action_12538058 ] 

Steve Hawkins commented on TEIID-1144:
--------------------------------------

ProjectNode, SelectNode, and the XML Plan IfInstruction are not written to safely handle TimesliceExpired exceptions.  So operations that are taking over 2 seconds per batch may lead to inaccurate results.

> Several BQT queries are failing in PostgreSQL (simple capabilities) with an unexpected number of rows returned.  
> An example query can be seen below.  This query is expecting 50 rows returned since there are 50 rows in smalla table but 
> only 44 rows are returned.
> SELECT * FROM BQT1.SmallA AS A WHERE EXISTS (SELECT INTKEY FROM BQT1.SmallA AS B WHERE B.INTKEY = A.INTKEY)
> vdb is attached.
