RE: Interupting an rpg sql search

Nothing RPG specific I can think of.

You should still be able to use the SYSREQ key, which IBM's iSeries Access emulator defaults to
Shift-Esc.

SYSREQ is different than SYSATTN.

SYSRQ will interrupt whatever the terminal is doing, SYSATTN won't.

SYSREQ might still take awhile, depending on what's being done.

Are you using LIKE 'SOMETHING% or LIKE '%SOMETHING%'? The first will use an index, make sure it's
available. The second won't.

If using '%SOMETHING%', you might be able to speed things up by having a separate dictionary file that
you can build an index over.

Subject: Interupting an rpg sql search

I have a SQLRPGLE program that does a search using "like" over a large
file.
The search can take a bit a time in some cases. I would like to be able to
stop the search by hitting a key (say esc key tied to an attention
program).



Can this be done? Or are there other techniques I can use. I've tried the
"fetch first 25 rows only" clause, but the search still can take a long
time.
