So, in programs that do a dynamic SQL, would it be of value to place a simple "dummy" (but well documented) static statement that simply selects all records of the file(s) that would be dynamically used elsewhere later, just to get the PRTSQLINF to recognize that the file is used in the program.

Kind of hokey, but a trick used often in "do while 1 = 2" code to perform similar functions... which elude me right now for examples.

I wouldn't typically suggest excess code, but I understand Jeff's dilemma. It's similar to trying to find all the QRY400s that use files or fields.

Of course the alternate would be a well-documented change management system.

Re: Files used by SQL in RPGLE

Hi John,
Try the PRTSQLINF command. See if that gives you what you need.

PRTSQLINF will give you the files used for static SQL. If you're using dynamic SQL all it will give you is the fact that you're preparing a statement from a host variable. Someone will have to analyze what can be in the host variable at the time of the prepare.

This is another gotcha in addition to the performance implications of dynamic SQL.
