I recently upgraded from Teiid 8.12.3 to version 9.1.1. And I found query transformation problem for oracle 12c.

I have a simple query. See below:

select "STORE_CITY"

from "jasperserver_FOODMART"."STORE"

limit 200001

However, teiid version 9.1.1 transformed the query to

Caused by: org.teiid.jdbc.TeiidSQLException: TEIID30504 1017993016: 1741 TEIID11008:TEIID11004 Error executing statement(s): [Prepared Values: [] SQL: SELECT c_0 FROM (SELECT g_0."STORE_CITY" AS c_0 FROM "FOODMART".""."STORE" g_0) WHERE ROWNUM <= 200001]

It looks like it's returning an empty string for the catalog. The code currently expects a non-null to indicate the package name.
