Re: VARPG, VB and WebFacing

Hi John,

I don't know if this applies to VARPG, or whether you've already noticed it,
but when using VB with ADO, we chose SQL over record-level access because
the error message would give constraint names. By using very long
description constraint names it became relatively easy to figure out what
the error was talking about.
