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 ;

How can we replace the plsql code with count to postgresql
FOR I IN 1..variable.count
Loop
Cr:= varray (i)
End loop;
Replacement for count in postgresql
This can be executed like a normal query :
$$ declares a string works same as '' ,example: SELECT $$string$$; or SELECT $string$ 'text' $string$;
DO indicate the next string will be executed.
DO
$$

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'm trying to query a table with a lot of columns like debMonth1, debMonth2 etc. to get a result that fits the needs for the application that needs to process the data.
Syntactically the query seems to be OK now, but I don't get a result from it. It just proceeds with no error.
I think I got problems regarding the column names? Can anybody help me out?
DO $do$
DECLARE cmonth TEXT;
DECLARE dmonth TEXT;
BEGIN
FOR i IN 1..15 LOOP
cmonth = CONCAT('"credMonth' , i::text, '"');
dmonth = CONCAT('"debMonth' , i::text, '"');
EXECUTE
format('SELECT
"account", "FY", "setOfBooks", $1, $2, $3 AS "fiscalMonth"
FROM
"transaction_figures"
WHERE
"dataType" = ''(80)'' AND
($1 != ''0.00'' OR $2 != ''0.00'')')
USING cmonth, dmonth, i;
END LOOP;
END
$do$ LANGUAGE plpgsql;
Queries executed in plpgsql don't result in printing its output nor sending to client. You have to iterate over the results and do something with it, for example:
DO $do$
DECLARE cmonth TEXT;
DECLARE dmonth TEXT;
DECLARE r RECORD;
BEGIN
FOR i IN 1..15 LOOP
cmonth = CONCAT('"credMonth' , i::text, '"');
dmonth = CONCAT('"debMonth' , i::text, '"');
FOR r in
EXECUTE
format('SELECT
"account", "FY", "setOfBooks", $1, $2, $3 AS "fiscalMonth"
FROM
"transaction_figures"
WHERE
"dataType" = ''(80)'' AND
($1 != ''0.00'' OR $2 != ''0.00'')')
USING cmonth, dmonth, i
LOOP
RAISE NOTICE '%', r;
END LOOP;
END LOOP;
END
$do$ LANGUAGE plpgsql;
This will print results in psql. If you would like to have data behaving like table (i.e. sent to client) you have to wrap your code in plpgsql function and return query result.

You are trying to use a MySQL (or other DB?) function in PostgreSQL. There is no concept of CONTINUE HANDLER in PostgreSQL, so you have to convert the function into PostgreSQL format.
drop FUNCTION if exists migratePartnerAdvertiser();
CREATE OR REPLACE FUNCTION migratePartnerAdvertiser() RETURNS int4 AS '

BEGIN
FOR r IN select distinct COLUMN_NAME from INFORMATION_SCHEMA.COLUMNS where TABLE_NAME = ''currentdiagnosis'' and table_schema=''public'' LOOP

I'm trying to get my first ever trigger and function to work, but how I throw exceptions and return data right way?

You've got an error here:
SELECT
COUNT(id) AS c
FROM
"SHIFTS"
WHERE
employee_id = _employeeid AND
status = 1 AND
(
(starts BETWEEN _start AND _end)
OR
(ends BETWEEN _start AND _end)
)
;
Such a select in a plpgsql procedure has to be SELECT INTO... like this:
DECLARE
c INTEGER;
BEGIN
SELECT
COUNT(id)
INTO c
FROM
"SHIFTS"
WHERE
employee_id = _employeeid AND
status = 1 AND
(
(starts BETWEEN _start AND _end)
OR
(ends BETWEEN _start AND _end)
)
;
RETURN (c > 0);
END;
And here you've got to have the semicolon at the end of the line:
enter code here`RAISE EXCEPTION "Shift is locked";
Not sure what you're trying to find out. You're managing to raise your own exceptions, so that's good. I would expect that any error handling would be in the code that evokes this method.
If you want to do something inside the procedure, you need an EXCEPTION section:
[ <> ]
[ DECLARE
declarations ]
BEGIN
statements
EXCEPTION
WHEN condition [ OR condition ... ] THEN
handler_statements
[ WHEN condition [ OR condition ... ] THEN
handler_statements
... ]
END;
But generally I would expect you'd handle it in the calling code.
You have to use SELECT INTO to get a value returned by a query
DECLARE
[...]
c boolean;
SELECT
COUNT(id) INTO c
FROM
"SHIFTS"
WHERE
[...]
