Luke writes "Hi

I am brand spanking new to SQL and havent much knowledge on how to do simple things.

Is there a way of running a script that would throw up an error if there were more than 10 characters and less than 10 characters?

I am thinking Left count and Right count type of commands?

Many thanks for any help you can offer.

Luke"

Why bother with LEFT() or RIGHT()? Use LEN()

If len(@Param) <> 10 then
   RAISERROR('Param must be 10 characters long', 16, 1)
