Mike Matrigali updated DERBY-2507:
----------------------------------

    Component/s: SQL

> 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
>          Components: SQL
>    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.
> See this thread for more details:
