RE: SQL performance

["Bartell, Aaron L. (TC)" <ALBartell@xxxxxxxxxxxxxx>]

I agree.  It definitely shouldn't be taking that long.  I have a file with
roughly 18 million records in it, and when I run a select on a non-keyed
field it only takes up to 20 minutes tops, and that is with a "LIKE" clause!

Can we see all of the embedded SQL in question. What you're saying doesn't
make sense. Embedded might be a bit slower but not that order of magnitude.

Subject: SQL performance


Hello all,

I am having a problem with query performance with embedded SQL in an RPGLE
procedure. The table in question has about 2m rows. If I issue an
interactive SQL statement, using the same criteria, the results are
relatively quick but the same statement within an RPGLE procedure is
ridiculous. The program ran for 1 1/2 hours and failed to process one
detail record. Any help would be appreciated. The table in question is a
saved inventory history table over which there are no indexes. Just the
primary key. I'd hate to create a logical file over this thing for one
procedure.


Thanks,

Mark
