Did the index help speed it up?
Also, is the file journaled or have triggers or constraints on it -  and
how is your RPG-SQL program compiled (with or without commitment control)?

Thanks for all who responded so far...

More info:

The file has no indexes.  (I just added one by company to test some things
out.)

The file will delete a high percentage of records (from 50% to 100%, based
on
the number of companies currently being processed.)  I can only delete the
records of the company being processed, so that eliminates DROPping and
reCREATEing the file.

Will a non-unique index help with this high of a delete percentage?

Is there a way to "turn off" the overhead for this file, because I really
use
it as a work file (but I must keep it until I run the process again.)

... a tricky thing, this SQL stuff...
