RE: Select Row

OK, no one make fun of me.  SQL and me are not close friends at all.
 
Would this work for you?  Can you define your cursor as 10 records long? 
Then each fetch would get 10 records, or however many are left in the file.

Steve,
 
I saw your post almost right after I sent mine (it takes forever for my
e-mails to make the round trip for some reason) and you're right, the fetch
xx rows does work on V5R1. Thanks for sharing that, I'm sure it will come in
handy.
 
As for the RRN trick, I didn't mean to say it doesn't work at all, I meant
to say it isn't all that useful for selecting x number of rows on real world
files. For example, let's say you try your example where CUNBR > 9000 and
CUNBR < 10000 and RRN < 10. Chances are, none of these records will have a
RRN less than 10 so you get no data.

this trick all but useless in most cases.
 
Matt:
 
I don't know about prior releases, but both of the following SQL statements
work on V5R1:
 
select *from cusmst fetch first 2 rows only
SELECT statement run complete.
 
SELECT * FROM cusmst WHERE CUNBR < 100 AND rrn(cusmst) < 10
SELECT statement run complete.
