But we're not locking on the record we are attempting to update. We are
locking on the record we are attempting to get data from.

Dave - wont the same thing happen if you attempt to update a record in
RPG/RPGILE/COBOL etc, if the program does NOT have a lock on that
record.
If another user has a lock on that record, the program cannot get an
exclusive lock

I have a fellow programmer who has this code in a CL program:

Update OEP013W a set a.wkclosr =
   (select mtclon from OETITLP b where a.wkorder = b.mtordn)
   where a.wkclosr = 0

Where OEP013W is a work file in QTEMP; OETITLP is a production PF.

If someone is in the record (locking it) this statement fails.

If you do the sub-SELECT statement by itself with someone locking the
record, it doesn't fail.

Does a SELECT in an UPDATE statement have different rules?

It was our understanding that a SELECT did not lock, or require a
lock, and we assumed would not be inhibited by someone else locking a
record in that file.

TIA

Dave
