             Summary: Teradata IN pushdown issues
                 Key: TEIID-2064
                 URL: https://issues.jboss.org/browse/TEIID-2064
             Project: Teiid
          Issue Type: Bug
          Components: JDBC Connector
    Affects Versions: 7.4.1
            Reporter: Steven Hawkins
            Assignee: Steven Hawkins
             Fix For: 8.1

In predicates for Teradata are always being expanded to AND/ORs of comparison criteria.  This should only be needed if the predicate values contain a non-literal.  Also the logic does not nest the expansion in parens, which can cause the evaluation to be incorrect when the IN was on the left hand side of an AndOr condition.
