Subject [jira] Created: (DERBY-2507) Query compiler assumes bad parameter type for ? is null expression

Query compiler assumes bad parameter type for ? is null expression
------------------------------------------------------------------

                 Key: DERBY-2507
                 URL: https://issues.apache.org/jira/browse/DERBY-2507
             Project: Derby
          Issue Type: Bug
    Affects Versions: 10.2.2.0
            Reporter: Xavier Hanin


When using '? is null' in a prepared Statement, the compiler assumes ? as VARCHAR parameter,
and thus fails if you bind a VARBINARY object to the parameter:
org.apache.derby.impl.jdbc.EmbedSQLException: An attempt was made to get a data value of type
'VARCHAR' from a data value of type 'VARBINARY'

In Derby 10.2..2.0, only the embededded driver has the problem, the client driver works properly.
