             Summary: Sybase translator error caused by change in ASCII function pushdown
                 Key: TEIID-5398
                 URL: https://issues.jboss.org/browse/TEIID-5398
             Project: Teiid
          Issue Type: Bug
          Components: Misc. Connectors
    Affects Versions: 8.12.14.6_4
            Reporter: Jan Stastny
            Assignee: Steven Hawkins
            Priority: Critical


Following query:
{code:sql}
SELECT INTKEY, ASCII(INTKEY) FROM BQT1.SmallA
{code}
being resolved to following src command:
{code:sql}
SELECT g_0.intkey, unicode(cast(g_0.intkey AS varchar(4000))) FROM smalla g_0
{code}
results in following error:

{code}

SRC Command in previous version:
{code:sql}
SELECT g_0.intkey, ascii(cast(g_0.intkey AS varchar(4000))) FROM smalla g_0
{code}

NOTE: the issue is not caused by casting int to varchar, happens also when calling ASCII function on string directly.
