>>I'm not sure I ever did this much, if any, and so it's been awhile since I thought much about this, but isn't it going to cause a problem if you create an index on an integer field where the index expression is ALLTRIM(STR(INTEGER_FLD))? That's going to create a variable length index, correct? And I'm not sure why you would index such a field - which is the PK in the table in question - on anything other than just the field itself (in other words, the index expression just contains the field name).

The index tag expression and the where/for clause have to match for Rushmore optimization. It's control over the length of the index expression that's important here.

So you INDEX ON PADL(ALLTRIM(STR(INTEGER_FLD)),10,'0') and you SELECT BLAH WHERE PADL(ALLTRIM(STR(INTEGER_FLD)),10,'0') = "0000000001" and it'll be fine.
