It would be a ton more than 3 because I also want

value,
value:
value+
value-

value/
value%
and that is just off of the top of my head. Not to mention I need all of
the combinations of these
+value*
*value+

Not pretty, but how about creating 3 like statements. I have this in an old
query that looks for the word file in member descriptions. There a space
between all the percent signs and the characters next to them.
where upper(ODOBTX) like 'FILE %'
or upper(odobtx) like '% FILE %'
or upper(odobtx) like '% FILE'

I was using the SQL version and performance landed on its face.
Using this in my join of two tables...
left join source on Regexp_like(srcdta,
'[^A-Za-z0-9_@#$]'||trim(field)||'[^A-Za-z0-9_@#$]','i')
it runs for about 5 minutes.
Switching to this (which only finds ACCT and doesn't eliminate prefixed or
suffixed values such as ACCT01)
left join source on srcdta like '%'||trim(field)||'%'
it runs in about 5 seconds.
These times are pretty consistent over multiple tests (alternating which is
executed first) so it is not caching or CPU bog down or any of that.
So. I thought I would switch to use the later and then then add the RegEx to
my RPG for the other part and see what that does.

Are you using the regex api's directly?
If so, I suggest you take a look at the SQL regexp_* functions.

They are much easier to work with IMO.
