Hello,
I need to pass a JSON argument in a procedure to use it in a FROM clause of a SELECT.
So far I try :
CREATE OR REPLACE PROCEDURE public.test_json(Tparam VARCHAR(256)) LANGUAGE plpgsql
AS $$
DECLARE
elem VARCHAR(256);
BEGIN
DROP TABLE IF EXISTS temp ;
CREATE TABLE temp (jsonfield super);
INSERT INTO temp VALUES (JSON_PARSE(Tparam));
SELECT jsonfield."accountIds"[0] INTO elem FROM temp ;
SELECT myfield FROM mytable WHERE myfield=elem ;
END;
$$
But I would prefer to do it directly :
« SELECT jsonfield."accountIds"[0] INTO elem FROM Tparam ; »
If you a any idea I will be very happy.
