Re: How to manually load RETURNS SETOF RECORD?

RETURN NEXT ROW sounds like the ticket. I am trying to duplicate some
functionality that Oracle has in PL/SQL.

specifically
PROCEDURE dGetQuestionSetKeyOrder
(pweb_site_name_i IN
tx_web_site.web_site_name%TYPE,
pqs_table_i IN OUT NOCOPY
XPORTAL_QUESTION_SET_TABLE
)
where *xportal_question_set_table* is an array of OBJECTS. *Really it's an
array of composite types, but Oracle uses and Object to construct
a composite type. *

And later in the procedure body we see:
pqs_table_i.EXTEND;
pqs_table_i(pqs_table_i.LAST) :=
QUESTION_SET_KEY_ORDER_OBJECT(v_current_qs_key,
v_qs_table_cnt + 1);

This is appending data to pqs_table_i.

So, in a nutshell,
1. Pass in an array of composite type
2. Append to said array
3. Return updated array

Regards,
Mike
