I have a function that receives an integer[]
array as a parameter.
CREATE OR REPLACE FUNCTION public.get_master_products(P_PRODUCTS_IDS integer[])
RETURNS SETOF record
LANGUAGE plpgsql
AS
$body$
DECLARE
CURRENT_ID integer;
PRODUCT RECORD;
COMPONENT1 RECORD;
COMPONENT2 RECORD;
COMPONENT3 RECORD;
BEGIN
....
END;
And when I call this function I have to do it like this:
SELECT
"ID",
"CODE",
"CODE2",
"NAME",
"COMPOSERS",
"PTYPE_ID",
"PTYPE_NAME",
"COMPONENT_QUANTITY",
"UM_ID",
"LEVEL"
FROM
get_master_products(array[ 20, 40, 50, 80])
AS
(
"ID" integer,
"CODE" varchar,
"CODE2" varchar,
"NAME" varchar,
"COMPOSERS" numeric,
"PTYPE_ID" bigint,
"PTYPE_NAME" varchar,
"COMPONENT_QUANTITY" numeric,
"UM_ID" varchar,
"LEVEL" varchar
);
but is there a way to do something like this to call the function?:
get_master_products(array[ (SELECT id, FROM products WHERE composers > 0) ])
to automatically create the pass array with a SQL query??
Can you help me please.
Thank you
使用array_agg :
get_master_products(SELECT array_agg(id) FROM products WHERE composers > 0)
