Subject: RE: Performance SQL Delete vs RPGLE Delete

Somewhat beyond the scope of the question but if there is something that has
the file open, aren't you running the risk of deleting records that have not
yet been processed? I would be really concerned deleting all of the records
in the file if I didn't have 100% control of it.

Just my $.02 that on a subject where it wasn't asked for.

Subject: Performance SQL Delete vs RPGLE Delete

I know the normal answer is, depends. Just looking for thoughts.

I have a program (RPGLE) that has this code (the file has a lock on it
otherwise we would use CLRPFM or some other method).

Read FileA;
Dow not %eof(FileA);
Delete FileAr;
Read FileA;
Enddo;

How would the performance compare to SQL with something like, in that same
RPGLE program.
Exec SQL Set option Commit=*None
Exec SQL Delete From FileA;

FileA will have 0.5 - 6 million rows.
