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
