Thank you!
What kind of variable would I declare? Is this any form of right?
No change to subfunction.
In PARENT Function:
DECLARE v_outvar1 REFCURSOR; v_outvar2 REFCURSOR; v_outvar3 REFCURSOR;
?And use:
SELECT * INTO v_outvar1, v_outvar2, v_outvar3 FROM
dev.pr_test_subfunction(SWV_Action);
OPEN swv_refcur for SELECT v_outvar1;
OPEN swv_refcur2 for SELECT v_outvar2;
OPEN swv_refcur3 for SELECT v_outvar3;

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
SELECT * FROM dev.pr_test_subfunction(SWV_Action);
In pl/pgsql if you do not use an "INTO" clause on a select statement you
must replace the "SELECT" with "PERFORM". Failing to do so results in the
error you are seeing. In this case your calls to the sub-function do not
magically populate the parent function variables. You must manually map the
output of the sub-function call query onto the parent variables.
