Hi Craig,

The likely difference between your test and my use, is mine references the
IDENTITY_VAL_LOCAL() function inside an SQL statement that is ALSO a 3 part
SQL referencing the remote system. See example below.

Note: I've used this in ACS Run SQL Scripts, but I think it is very likely
to work elsewhere.

Example:

create table RMT_SYS.RMT_SCHEMA.TEST_ID
( ID bigint generated always as identity
,TEST_DATA char(1)
) ;

insert into RMT_SYS.RMT_SCHEMA.TEST_ID
( TEST_DATA ) values 'A';

insert into RMT_SYS.RMT_SCHEMA.TEST_ID
( TEST_DATA ) values trim( char( IDENTITY_VAL_LOCAL() ) );

select * from RMT_SYS.RMT_SCHEMA.TEST_ID;

--Result
ID TEST_DATA
1 A
2 1

IDENTITY_VAL_LOCAL() used in a non-3 part SQL will return the last ID
assigned on the LOCAL system.

IDENTITY_VAL_LOCAL() used in a 3 part SQL will return the last ID assigned
on the REMOTE system.

HTH,

Mike

Well,

It was easy enough to set this up and insert a record to a remote machine.
But when I call identity_val_local() after the insert it just returns null

To be clear, what I am doing is:
1. From Machine A, using 3-part SQL to insert a record into a table on
Machine B which has an always generated identity column.
2. From Machine A, trying to call identity_val_local() to find the latest
identity value assigned.

Identity_Val_Local() always returns null.
I tried this via the STRSQL command and also in an SQLRPGLE program.

I understand that this value would need to be retrieved from the job
running on the remote machine which actually does the work. I'd hoped it
might be smart enough to figure it out...
I'm lead to believe that it should work via a JDBC connection.

Mike - I thought you said this worked for you, but the scenario you
described isn't the same as far as I can tell.

thanks and regards,
Craig
