------------------------------------
Thank you for the commit knut. This patch blocks issue 2443 and this commit
will help me in submitting a final patch to that issue.
Thanx a ton for this one,

> setObject(int targetType, Blob source) and setObject(int targetType, Clob
> source) should disallow updates on all targetTypes except BLOB and CLOB
> respectively

> updateBlob(int columnIndex, Blob x), updateClob(int columnIndex, Clob x) can
> be implemented by forwarding calls to setObject(int targetType, Blob
> source), setObject(int targetType, Clob source). If this this done then
> 1) updateClob on a CHAR/VARCHAR/LONG VARCHAR column throws an exception on
> the Embedded Driver but not on the NetworkClient
> 2) updateBlob works on a CHAR/VARCHAR/LONG VARCHAR FOR BIT DATA throws an
> exception on the Embedded Driver but not on the NetworkClient
> From what the JDBC 4.0 spec says (pg 198 table b-5) the Embedded behaviour
> seems to be correct.
> This can be fixed by Matching Embedded behaviour. This would involve throwing
> an exception in the cases mentioned above
