> Recently, I went through the excercise of porting a larger jdbc code-base from
> mysql to oracle. There may be many reasons to do this, but error handling in
> ojdbc14.jar is not one of it  :(   {the usual laziness of programmers when
> throwing an error: not saying which of the parameters caused it, not citing
> offending values, string positions of invalid characters, ... - it would cost
> them a few minutes to do better and save the developers using their jar days if
> not weeks!}
> Therefore the RFE:
> Not only directly pass on all values in DelegatingCallableStatement and
> DelegatingPreparedStatement to the delegate, but in the set*() methods gather
> enough information to be able to do something along the lines of
> com.mysql.jdbc.PreparedStatement.asSql()
> Sure one might say that this causes unneccessary overhead for production
> environments - o.k. perhaps there needs to be a configuration flag to set
> whether dbcp shall do this or operate as is.
