Hi Steve
I'm curious - what advantage do you have for there being multiple records with the same sequence number (but different fieldA)?

The sequence is based on a field in the file, so there could be multiple records with same seq# Example file would be FieldA, Seq

File:

FieldA = "TEST" Seq = 1
FieldA = "TEST" Seq = 2
FieldA = 'ROB' Seq = 1
FieldA = 'STEVE' Seq = 1

Never saw a identity column before, that would be perfect.

Can the number be based on like key field? In your example:

1, A, 1
1, A, 2
2, B, 1

As Birgitta said, a before insert is what you want.

I do have to ask though. Why not use an identity column and have
the system autoincrement it for you?

Create table...
myKeyColumn int as identity,
...

Or perhaps a sequence object? Below is a tested example of sequence
created with "Run SQL Scripts":

set current schema rob;

create or replace sequence NextKey;

create table scuzz (
myKeyColumn int as identity,
SomeOtherColumn char(5),
CounterNumber int);

insert into scuzz
(SomeOtherColumn, CounterNumber)
values ('A', next value for NextKey);

insert into scuzz
(SomeOtherColumn, CounterNumber)
values ('B', next value for NextKey);

select * from scuzz;
you will see:
1, A, 1
2, B, 2

values previous value for NextKey;
You will see: 2

If you want to know what object it creates try DSPDTAARA. It's
rather complex though.
Data area . . . . . . . : NEXTKEY
Library . . . . . . . : ROB
Type . . . . . . . . . : *CHAR
Length . . . . . . . . : 2000
I think it uses all that space to keep track of last accessed
information.

We have a file that contains a sequence number for each unique key
in
the
file, file is defined like this:

Filea:
Field1 (key1)
Field2 (key2)
sequence number (starts at 1)

We want to have a trigger program fire when a record is added to set
the sequence number of the new record to be the next #.

So I tried adding a trigger with trigger time of *after & event
*insert, that fails because the record is still in use.

Seems like a simple idea, but we are missing something.

Thanks
