[teiid-issues] [JBoss JIRA] (TEIID-2779) Configurable CommonTableExpression support for DB2

[Andriy Rokhmanov (JIRA)]

    [ https://issues.jboss.org/browse/TEIID-2779?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12933886#comment-12933886 ] 

Andriy Rokhmanov commented on TEIID-2779:
-----------------------------------------

We did additional research, seems DB2 for z/OS V9.1 in Conversion Mode does not support ORDER BY inside CTE either. Error message we are getting: "ATTEMPT TO USE NEW FUNCTION BEFORE NEW FUNCTION MODE. SQLCODE=-4700, SQLSTATE=56038, DRIVER=4.12.55"
The approach proposed on 20/Dec/13 3:46 PM does not help either. This makes CTE approach for DB2 on z/OS a very difficult to keep for certain DB2 versions.

> The LIMIT clause (FETCH FIRST...) inside CTE (WITH...) is not supported on pre-V9 versions of DB2 on z/OS, or new versions of DB2 running in Compatibility Mode.
> The CTE support in DB2 translator should be configurable.
