-------------------------------------

             Summary: Oracle comparison with binding of nchar with non-ascii chars is not correct
                 Key: TEIID-5687
                 URL: https://issues.jboss.org/browse/TEIID-5687
             Project: Teiid
          Issue Type: Bug
          Components: JDBC Connector
            Reporter: Steven Hawkins
            Assignee: Steven Hawkins
             Fix For: 12.2


An nchar column binding in the where clause will use the FIXED_CHAR (999) oracle type - however that converts the value to ascii, which may result in invalid results:

nchar_col = ?

where ? is bound to Ā would search instead for A.
