greetings. I'm trying to write a function that acts like a switchboard,
calling other functions depending on incoming parameters.
I'm getting error: query has no destination for result data
Please advise what we're doing wrong. The subfunctions return a series of
refcursors in a single table and single row (see pr_test_subfunction).
When i run the parent function, i want to see the same results as if i had
run the subfunction - the results of the subfunction should pass-thru to the
parent calling function. Can this be done?
Subfunction:
[CODE]
CREATE OR REPLACE FUNCTION dev.pr_test_subfunction (
v_action varchar,
out swv_refcur refcursor,
out swv_refcur2 refcursor,
out swv_refcur3 refcursor,
out swv_refcur4 refcursor,
out swv_refcur5 refcursor
)
RETURNS record AS
$body$
DECLARE
SWV_Action VARCHAR(50) DEFAULT Coalesce(v_Action,'');
BEGIN
OPEN SWV_RefCur for SELECT 1;
OPEN swv_refcur2 for SELECT 2;
OPEN swv_refcur3 for SELECT 3;
OPEN swv_refcur4 for SELECT 4;
OPEN swv_refcur5 for SELECT 5;
RETURN;
END;
$body$
LANGUAGE 'plpgsql'
VOLATILE
CALLED ON NULL INPUT
SECURITY INVOKER
COST 100;
[/CODE]
Parent Function:
[CODE]
CREATE OR REPLACE FUNCTION dev.pr_test_parentfunction (
v_action varchar,
out swv_refcur refcursor,
out swv_refcur2 refcursor,
out swv_refcur3 refcursor,
out swv_refcur4 refcursor,
out swv_refcur5 refcursor
)
RETURNS record AS
$body$
DECLARE
SWV_Action VARCHAR(50) DEFAULT Coalesce(v_Action,'1');
BEGIN
IF SWV_Action = '1' THEN
SELECT * FROM dev.pr_test_subfunction(SWV_Action);
ELSIF SWV_Action = '2' THEN
SELECT * FROM dev.pr_test_subfunction(SWV_Action);
ELSE
OPEN SWV_RefCur for SELECT 1;
OPEN swv_refcur2 for SELECT 2;
END IF;
RETURN;
END;
$body$
LANGUAGE 'plpgsql'
VOLATILE
CALLED ON NULL INPUT
SECURITY INVOKER
COST 100;
[/CODE]
