Please let me know if there is any part of query is which cannot be understood.
The variable "hell" sounds like useless here, try something like this :
create or replace procedure "public"."extract"(arg json)
language plpgsql as $$
begin
raise notice 'test:%', arg->'global'->>'packetType';
raise notice 'test1:%', arg-> 'transactional'->>'A';
-- freeze the input
end ;

I have a syntax error on a procedure (PostgreSQL) and I can't find the mistake. I need a procedure with the variable declaration, a for loop, and a transaction.
Here is a sample of the structure I'm using.
CREATE OR REPLACE PROCEDURE repor_dados()
LANGUAGE plpgsql AS
$$
DECLARE
utilizador int;
data_acesso date;
r record;
BEGIN
BEGIN -- begin transaction
select 2 ,4 into data_acesso,utilizador;
IF EXISTS(select 2) then -- condition
BEGIN
-- for each select result
FOR r IN SELECT 1,2,3
LOOP
-- do something
IF r = 1 THEN
SELECT 3;
ELSE
SELECT 4;
END IF;
END LOOP;
END;
COMMIT; -- commit transaction
END

I am working with PostgreSQL 13.2.
The error is:
ERROR: syntax error at end of input LINE 30: $$
I have a function that accepts an array of table names and loops through the array to create a trigger for each table. The function compiles and is created with no errors.
When I go try to run the function I keep getting the following error and I am not sure what's wrong with my syntax

Im unable to understand why the error is at the PIPE symbol. Please help me. I have been trying in Oracle db too, but same error. Am I doing anything wrong here?
The query in for ... loop statement also has to be dynamic, so you should use execute twice.
Use the format() function which is very convenient in conjunction with execute:
do $xyz$
declare
y text;
i record;
begin
y := to_char(current_timestamp, 'YYYYMMDDHHMMSS');
raise notice '%', y;
execute format($ex$
create temp table somenewtable%s
as select * from (
values
(0::int, -99999::numeric),
(1::int, 100::numeric)
) as t (key, value)
$ex$, y);
for i in
execute format($ex$
select * from somenewtable%s
$ex$, y)
loop
raise notice '%',i.key;
end loop;
end;
$xyz$ language 'plpgsql';
I'm trying to run a DELETE and UPDATE query inside a trigger function in PL/pgSQL.
CREATE OR REPLACE FUNCTION trg_delete_order_layer()
RETURNS trigger AS
$BODY$
DECLARE index_ INTEGER;
DECLARE a RECORD;
BEGIN
IF EXISTS (SELECT * FROM map_layers_order WHERE id_map = OLD.id_map)
THEN index_ := position FROM map_layers_order WHERE id_map = OLD.id_map AND id_layer = OLD.id_layer AND layer_type = 'layer';
ELSE index_ := 0;
END IF;
RAISE NOTICE 'max_index % % %', index_, OLD.id_map, OLD.id_layer;
EXECUTE 'DELETE FROM map_layers_order WHERE id_map = $1 AND id_layer = $2 AND layer_type = $3' USING OLD.id_map, OLD.id_layer, 'layer';
EXECUTE 'UPDATE map_layers_order SET position = position -1 WHERE id_map = $1 AND position > $2' USING OLD.id_map, index_;
VALUES (OLD.id_map, OLD.id_layer, 'layer', index_);
RETURN OLD;
END;
$BODY$
LANGUAGE plpgsql;
I don't know why i'm getting this error in the line where it runs the DELETE query:
Query has no destination for result data
Why is this error happen and how can I solve this?
Obviously if I use EXECUTE...INTO, I get a more reasonable error saying that the query has no result.
