RE: SQL Query Scalar Function Versus Second Table

["Wilt, Charles" <CWilt@xxxxxxxxxxxx>]

Pillai,

If it helps, I don't know of any way to build an index on replace(part,'-',''). 
 Unless that value is stored in another file.

I'd recommend a trigger on the original file that maintains the new 
'dictionary' file.

That's how I like to do these things.
