Re: SQL on V5R1

Charles,

<snip>
Lots of downsides to this, including the fact that there'd be no built in
way to let the program doing the write know what identity value was
generated.
</snip>

There are multiple ways of learning the last generated identity column.
One is by the scalar built in function IDENTITY_VAL_LOCAL as in
INSERT INTO EMPLOYEE
(NAME, SALARY, DEPTNO)
VALUES('Rupert', 989.99, 50)

VALUES IDENTITY_VAL_LOCAL() INTO :IVAR
I suspect this came out when, or after, support for GENERATED was added

Another is "select from insert"
select *
from final table (
INSERT INTO EMPLOYEE
(NAME, SALARY, DEPTNO)
VALUES('Rupert', 989.99, 50)
)
But I think this came out in 6.1
http://www-01.ibm.com/support/knowledgecenter/ssw_ibm_i_61/sqlp/rbafysfins.htm?lang=en-us

But, *IF* it was supported back then, I would think it would have the
potential to find the data inserted by the trigger.
