[Mark Tawk (JIRA)]

    [ https://issues.jboss.org/browse/TEIID-4129?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13191370#comment-13191370 ] 

Mark Tawk commented on TEIID-4129:
----------------------------------

You find attached the MetaDataStore of the 2 corresponding DBs.
The corresponding fields types are VARCHAR_IGNORECASE, and the joined data values have exactly the same case.

> I'm using Teiid 8.11.3 with H2 translator.
> I'm joining 2 h2 tables from 2 different teiid models linked on varchar fields.
> the query result is retuning empty values from the joined table even though the joined values are identical.
> You find attached a zip file containing 2 h2 DBs for a simplified example
> Here is the query used:
> _select "Customer"."City" as "Customer_City","Customer"."CustomerID" as "Customer_CustomerID","City"."City" as "City_City","City"."CityID" as "City_CityID" 
> from "db2"."Customer" "Customer" 
> LEFT JOIN "db1"."City" "City" ON "Customer"."City" = "City"."City"_
> Note that if the 2 tables are in the same model, the query return correct results.
