It's magic, 'cause also unnamned params (?) are not supported. Looks like some Cut'n'Paste implementation from another provider. AFAIK Oracle has own provider on his site (I don't know differences between framework's and "internal, but ...) - maybe it handles params right. > I couldn't find any nice workaround.

Maybe you need something, that can be easily solved in another way. BTW If you want to your application be able to work with oracle and FB using same code and there's a problem with oracle-provider, why not to use some constants and prefix params with it depending on selected provider. It's not clear, it's not nice, but it solves problem. > Regards., > ...michal > > Jiri Cincura pisze: > > On 8/27/07, [EMAIL PROTECTED] <[EMAIL PROTECTED]> wrote: > >> Hello, > >> I need to have the C# .NET 2.0 application that could use both firebird > >> and/or oracle as a database engine.
