[teiid-issues] [JBoss JIRA] (TEIID-4427) Migration to Teiid 9.0.0 - Materialized views error: Expected integer, but was bigdecimal

[Steven Hawkins (JIRA)]

    [ https://issues.jboss.org/browse/TEIID-4427?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13293314#comment-13293314 ] 

Steven Hawkins commented on TEIID-4427:
---------------------------------------

> i'm counting on ResultSetMetaDataImpl to create the view and stage tables columns data types; in the case of Aggregate function COUNT, the meta is returning Integer.

That is correct that count returns an integer.  From that you are creating the DDL for a mysql table?  Are you mapping that to an unsigned int in mysql?

I'm still fuzzy on just exactly how the Teiid metadata for the materialization target is being created.  It seems from these comments that it must be happening via the translator import - but that hasn't changed in any significant way in between the releases in question.

> After migrating to Teiid 9.0.0, we are facing issues with existing views materialized on Oracle server.
> when fetching an Oracle materialized view that contains a column using date function like : "Month" or "Year" or "TIMESTAMPDIFF", we are getting the error : Expected integer, but was bigdecimal.
> If we go back to Teiid 8.11.3, the same materialized views fetch without any problem.
