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

             Summary: Oracle 11 drivers don't accept NVARCHAR type
                 Key: TEIID-5587
                 URL: https://issues.jboss.org/browse/TEIID-5587
             Project: Teiid
          Issue Type: Bug
          Components: JDBC Connector
            Reporter: Steven Hawkins
            Assignee: Steven Hawkins
             Fix For: 12.0, 11.2.2


Older oracle drivers, such as 11.2.0.1.0 do not accept the sql type NVARCHAR as an argument to set object, which results in an exception like:

{code}
Caused by: java.sql.SQLException: Invalid column type
	at oracle.jdbc.driver.OraclePreparedStatement.setObjectCritical(OraclePreparedStatement.java:12187)
	at oracle.jdbc.driver.OraclePreparedStatement.setObjectInternal(OraclePreparedStatement.java:11577)
	at oracle.jdbc.driver.OraclePreparedStatement.setObject(OraclePreparedStatement.java:12286)
	at oracle.jdbc.driver.OraclePreparedStatementWrapper.setObject(OraclePreparedStatementWrapper.java:548)
	at org.teiid.translator.jdbc.JDBCExecutionFactory.bindValue(JDBCExecutionFactory.java:1145)
{code}

We can also safely narrow our usage of the n types with oracle as anything in the latin 1 supplement is still allowed in varchar values.
