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. Andy Jim Buttafuoco wrote: > Andy, > > char(10) is padded with spaces while varchar is not.
