Re: Npgsql MS 2.0 - char bug?

Hi Jim,

Thanks for the reply.

I've used char because the field data is always going to be 10
characters, without exception. It's basically an ID field, which is
generated automatically by the field's default definition - and results
in values like DOM0000001, DOM0000002, DOM0000003 etc.
