Ahh thanks, Ryan.  That select was taking about a minute and a half covering about 500k rows, so I'm not sure if that's considered a good return time or not. ...

Thanks!  That worked like a charm!  Here's the final line:

(CONVERT(char,G.sdtT,101) = CONVERT(char,H.sdtT,101))

I can export to comma delimited.

And if I can import it using a stored procedure, I'd probably use a table variable, so I can do all my checking and manipulating...
