I have an insert using a select of sequences.
insert into ...
select
nextval('n') as a,
currval('n') as b,
...
from lalala
;
Is the order of the target list guaranteed?
That is, will the a and b in the above selection
*always* be the same?
My experiments show this to be true, but I
would like to know that the evaluation of the
target list is never rearranged so that the
values are always predictable.
Thanks,
elein
