I am trying to use a charlist wildcard to select surnames that do not begin with WGP but the code i am using is just doing the exact opposite!

So basically, i want to select surnames that do not begin with W, G or P my code is:

SELECT * FROM Person WHERE LastName LIKE '[!wgp]%'

and it is just brining up the surnames that DO start with these letters, quite irritating

Thanks for any help.
