Is there a way to set the auto-increment for a particular table to =
increase by some number more than one, like maybe 10?
Thanks in advance,

The manual is your friend. Don't be afraid of it :)

I have read the manual, and you're right, the auto-increment_increment =
is a system wide setting. I only want this on one table. I am in this =
instance creating ID's for a separate system via HL7 for a Filemaker =
system, and FileMaker is too lame and slow to actually spit out an ID in =
time for the foreign system to function correctly within its workflow =
requirements for the end users. So, I am going to offset the ID's so =
that MySQL issues ID's on the 10's, and FM issues ID's on the 5's. That =
way, it works similar to the way some people set up replication, but I =
only need it on this one table, I want the other tables to continue to =
increment normally. I don't want to do this in another instance of MySQL =
or another DB because I am otherwise trying to keep it simple. Here is =
the solution I came up with:
CREATE DEFINER=3D`user`@`%` TRIGGER `XXXX`.`p_number_zzk`
BEFORE INSERT ON `XXXX`.`p_number`
FOR EACH ROW
BEGIN
DECLARE maxy INT;
SET maxy =3D (SELECT ROUND(MAX(zzk),-1) from p_number);
IF ! NEW.zzk THEN
SET NEW.zzk =3D (maxy + 10);
END IF;
SET NEW.IdPatient =3D CONCAT("P", NEW.zzk);
END
It's probably ugly, but it works. Any objections to this? The zzk and =
IdPatient fields have unique validations on them.
Thanks,

This doesn't work, it just sets the starting number, but it will still =
increment by one unless you set the auto_increment_increment system =
variable, but this affects all the tables in the DB and not just the =
particular table.
Thanks,

this was not the question, but hopefully your app does not inline-query i=
n
every second line, if so you should think about the apllication design
it is generally senseless to change this value if you are not using
master/master-replications where you do this globally
