Re: SQL Query Scalar Function Versus Second Table

[Wayne McAlpine <wayne.mcalpine@xxxxxxxxxxxxxxxxx>]

I think the real solution is to re-think the underlying key.  If you had 
a two-part key consisting of the alphabetic code and a six-digit numeric 
field, you could use an edit code to allow entry of the dashes while the 
underlying numeric value would always be returned in its correct form. 
Your logical would have a composite key of both fields.
