The internal search function is temporarily non-functional. The current search engine is no longer viable and we are researching alternatives.
As a stop gap measure, we are using Google's custom search engine service.
If you know of an easy to use, open source, search engine ... please contact support@midrange.com.
Charles,

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.

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

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