Re: Stored Procedure (or SQL) to get a value then update it to +1

I would love to call an RPG program, but the program was written in the
late 90s in the early-mid 90s style. So they didn't break out logic or used
"good design". I figured at this point calling a stored procedure would be
best.

To add to my post just now - isn't it just so much easier to use a
native RPG READ, then store the value, then bump it and UPDATE the
record? This is where SQL seems to be the wrong approach - although
doable, it's rather cumbersome.

Maybe!!

I think there is a "SECUENCE" type of object in SQL, that increments in
1 each time it is used.

Other option is to create a view as "select max(usedkey) + 1 from

your.file

Stored procedures are not strong in this one.;-)

We have a "constant" file that holds the next sequence number for one of
our applications. I now need to access that from an external

application. I

am hoping I can write a stored procedure to essentially

SELECT nextkey from CONSTANT
UPDATE CONSTANT SET nextkey = nextkey + 1

How would I put this one stored procedure?
