Harold,

THANK YOU!! As I was writing that bit of code I had that creepy feeling
that "knew" that I was overlooking something simple. I guess I win the
"D'OH" prize for today.  8-D. (Maybe I shouldn't write any more SQL until
*after* the coffee kicks in......hmmm...)

Nice catch!
Shawn

This is the same as

  SELECT t1.*  FROM ytbl_development t1
  INNER JOIN tmpShortCodes sc
  ON t1.txtDevPostCode LIKE concat(sc.short_code, '%')

and this query would use indexes on txtDevPostCode and short_code.
