             Summary: Multi-source Dynamic vdb uses incorrect schema
                 Key: TEIID-2251
                 URL: https://issues.jboss.org/browse/TEIID-2251
             Project: Teiid
          Issue Type: Bug
          Components: Query Engine, Server
    Affects Versions: 8.1, 8.2
         Environment: Win XP pro, JBoss AS 7.1.1, JDBC drivers: system-i (jt400 7.8) , MySQL (connector/j 6.5.1)
            Reporter: Dave Stannard
            Assignee: Steven Hawkins


For a Multi-source, Dynamic vdb; Teiid issues queries with the catalog and schema of the the primary source.

If the non-primary source connection credentials have authority to access the primary's catalog/schema then duplicated rows are returned to the client.

If it does *not* have authority then an error results.

Note: In MySQL this effect can be mitigated by setting useCatalogName=false.  This seems to be because the JDBC4DatabaseMetaData.getTables() method does not return a schema; so suppressing the catalog is enough.

For the System-I whose equivalent getTables() method returns a catalog and schema, I couldn't find a workaround.
