Hi Rick,

Already a lot of responses, and certainly the numeric(11,0) should be
one you consider.

But if you want varchar, then can't you use

Check(Cast(Value as BigInt) between x and y)

(Substitute X and Y for the smallest largest legal values, I don't know
if you allow negatives. Also BigInt may need to be numeric(a,b)
depending on whether in your mind a decimal point is a valid character
in this field).

Hope that helps
Adam
