I have following procedure:
create or replace procedure todays_delivery_amount(targetkey_variable varchar)
returns number
language sql
as
$$
begin
if ((SELECT MONTHLY_DELIVERED_AMOUNT FROM test.process.msv_month_amount where TARGET_KEY = '20') = 0)
then
return ((SELECT monthly_target_amount from test.process.msv_month_amount)/3) ;
else
return ((SELECT monthly_target_amount from test.process.msv_month_amount where TARGET_KEY = '20') - (SELECT MONTHLY_DELIVERED_AMOUNT from test.process.msv_month_amount where TARGET_KEY = '20')) /
(SELECT (SELECT DATEDIFF(DAY,CONCAT(LEFT(current_date(), 8), '01')::date, CONCAT(LEFT(current_date(), 8), (SELECT datediff(dd,current_date(),dateadd(mm,1,current_date()))))::date+1)
- DATEDIFF(WEEK,CONCAT(LEFT(current_date(), 8), '01')::date, CONCAT(LEFT(current_date(), 8), (SELECT datediff(dd,current_date(),dateadd(mm,1,current_date()))))::date+1)) - RIGHT(current_date() -1, 2)::number + CAST(Round((day( current_date() ) +6)/7,0) as VARCHAR)::number);
end if;
end;
$$
;
UNSET todays_amount;
call todays_delivery_amount('10');
Now I want to do two things:
First I would like to save the output of the procedure in the variable todays_amount
So I tried this:
SET todays_amount = call todays_delivery_amount('10');
But this does not work.
And second:
Instead of where TARGET_KEY = '20' i would like to do where TARGET_KEY = targetkey_variable
But this does not work.
It appears that you can't set it directly from the call statement, but you can do this:
UNSET todays_amount;
call todays_delivery_amount('10');
set todays_amount = (select TODAYS_DELIVERY_AMOUNT from table(result_scan(last_query_id())));

I have following stored procedure in Snowflake:
create or replace procedure test_procedure(parameter varchar)
returns number
language sql
as
$$
begin
if ((SELECT MONTHLY_DELIVERED_AMOUNT FROM test.process.msv_month_amount where TARGET_KEY = parameter) = 0)
then
return null;
else
return (SELECT monthly_target_amount from test.process.msv_month_amount where TARGET_KEY = parameter);
end if;
end;
$$
;
call test_procedure('Key10');
When I try to call the test_procedure it give me following error:
SQL compilation error: error line 1 at position 98 invalid identifier 'parameter'
How do i fix this?
You should prefix the variable name with a colon.
create or replace procedure test_procedure(parameter varchar)
returns number
language sql
as
$$
begin
if ((SELECT MONTHLY_DELIVERED_AMOUNT FROM msv_month_amount where TARGET_KEY = :parameter) = 0)
then
return null;
else
return (SELECT monthly_target_amount from msv_month_amount where TARGET_KEY = :parameter);
end if;
end;
$$
;
call test_procedure('Key10');

User Parameter with single colon (:)
create or replace procedure test_procedure(parameter varchar)
returns number
language sql
as
$$
begin
if ((SELECT MONTHLY_DELIVERED_AMOUNT FROM test.process.msv_month_amount where TARGET_KEY = :parameter) = 0)
then
return null;
else
return (SELECT monthly_target_amount from test.process.msv_month_amount where TARGET_KEY = :parameter);
end if;
end;
$$
;
call test_procedure('Key10');
The code could be simplified to single query and CASE expression:
SELECT CASE WHEN MONTHLY_DELIVERED_AMOUNT = 0 THEN NULL
ELSE monthly_target_amount
END
FROM msv_month_amount
WHERE TARGET_KEY = :parameter

It doesn't update any of the row ?
In php connecting variable using . (dot), like $a = "tes", $b="b", if
I connect $a.$b it becomes "tesb". I want this but in postgres
I have tried using dot and + but wrong
my code
CREATE OR REPLACE FUNCTION make_ctx_contoh (rl varchar, dat varchar)
RETURNS numeric AS $total$
declare
date_before date;
dan text;
os_l numeric;
BEGIN
date_before = (DATE_TRUNC('month', NOW())
+ '0 MONTH'::INTERVAL
- '1 DAY'::INTERVAL)::DATE;
if rl = 'nasional' THEN
dan = '';
ELSEIF rl = 'kanwil' THEN
dan = 'AND LOWER(a."KANWIL") = knw';
ELSEIF rl = 'kc' THEN
dan = 'AND LOWER(a."KC") = kac';
END IF;
SELECT
SUM("a"."OUTSTANDING") into os_l
FROM
"public".tbl_nominatif_hasil AS "a"
WHERE
"a"."BUSS_DATE" = date_before AND
"a"."COLLDET" = '1 ' + dan; RETURN os_l;
END; $total$ LANGUAGE plpgsql;
When I run select make_ctx_contoh('kanwil','2'); that shows error like :
ERROR: operator does not exist: unknown + text LINE 6:
"a"."COLLDET" = '1 ' + dan
From what I could understand from your code, you want to add conditions to the where clause based on certain criteria.
So, convert your select query into a AND OR logic.
SELECT
SUM("a"."OUTSTANDING") into os_l
FROM "public".tbl_nominatif_hasil AS "a"
WHERE "a"."BUSS_DATE" = date_before AND
"a"."COLLDET" = 1
AND ( rl = 'nasional' OR
( rl = 'kanwil' AND LOWER(a."KANWIL") = knw) OR
( rl = 'kc' AND LOWER(a."KC") = kac')
)
I'm trying to use a part of a query into a variable , because I have many ifs to prepare the query , but I have not used something like this.

nRetorno number(14,2);
vSTRING VARCHAR2(2000);
begin
IF vTP_DADOS = 'VL_COMISSAO' THEN
vSTRING := 'SUM( DECODE( CPF.CD_MOEDA, 1, CPF.VL_COTACAO_UNIT * CPF.QTDE_COMPRA, ( SELECT Imp_Pack.fu_converte_moeda_ORACLE( CPF.CD_MOEDA, 1, CDT.DT_RECEBIMENTO, CPF.VL_COTACAO_UNIT, 1) * CPF.QTDE_COMPRA FROM dual ) ) )';

When you SELECT vString, the result is the content of the variable vString. It doesn't make any attempt to interpret that content as a column or expression. You are best off placing those expressions directly into the query.
IF vTP_DADOS = 'VL_COMISSAO' THEN
SELECT
SUM( DECODE( CPF.CD_MOEDA, 1,
CPF.VL_COTACAO_UNIT * CPF.QTDE_COMPRA,
( SELECT Imp_Pack.fu_converte_moeda_ORACLE( CPF.CD_MOEDA, 1,
CDT.DT_RECEBIMENTO, CPF.VL_COTACAO_UNIT, 1) *
CPF.QTDE_COMPRA
FROM dual ) ) )

I've got the following PL SQL function that returns a ref cursor but the application i am using does not support ref cursors. How can i make this code return something other than ref cursor

You can use a pipeline function to return a result set one record at a time, but in a way that the SQL engine can understand.
create or replace package WrapperSample is
type TResultRow is record(
if_type codes.cd%type
,number_infected Integer);
type TResultRowList is table of TResultRow;
function GetADedIcWarningsProv
(
p_hos_id in work_entity_data.hos_id%type
,p_date in date
) return TResultRowList
pipelined;
end WrapperSample;
/
create or replace package body WrapperSample is
function GetADedIcWarningsProv
(
p_hos_id in work_entity_data.hos_id%type
,p_date in date
) return TResultRowList
pipelined is
v_refcur eOdatatypes_package.eOrefcur;
currentRow TResultRow;
begin
v_refcur := YourSchema.getADedIcWarningsProv(p_hos_id, p_date);
loop
fetch v_refcur
INTO currentRow;
exit when v_refcur%NotFound;
pipe row(currentRow);
end loop;
close v_refcur;
return;
end;
end WrapperSample;
/
Using this package, you can select your ref cursor:
SELECT if_type
,number_infected
FROM table(WrapperSample.getADedIcWarningsProv(1, 2))
