I am trying to use Bulk all and Forall in Oracle database:
Original code from Procedure is as below:
IF NVL(v_mc,0) != 0 THEN
FOR rec IN
(SELECT a.testid,
SUM(pct * NVL(cap,0))/v_mc lead1
BULK COLLECT INTO testids1, testids2
FROM testtable a
WHERE a.id = n_id
AND a.type =n_type
GROUP BY a.testid;
)
LOOP
UPDATE testtable
SET LEAD1 =ROUND(testids2(i),2)
WHERE tid = n_id
AND type = n_type
AND testid =testids1(i);
END LOOP;
END IF;
So In select statement , I am using Sum function and also using aliasing here .
Code , I have written which use Bulk collect and Forall is as follows:
PROCEDURE test
IS
TYPE test1Tab IS TABLE OF sh_rpt_temp_peer_wip.test1%TYPE;
TYPE test2Tab IS TABLE OF testtable.lead1%TYPE;
testids1 testidTab; --Error 1 and Error 2
testids2 LeadTab;
BEGIN
IF NVL(v_mc,0) != 0 THEN
SELECT testid,
SUM(pct * NVL(cap,0))/v_mc lead1
BULK COLLECT INTO testids1, testids2
FROM testtable a --Error 3
WHERE a.id = n_id
AND a.type =n_type
GROUP BY a.testid ORDER BY a.testid;
FORALL i IN testids1.FIRST..testids1.LAST
UPDATE testtable
SET LEAD1 =ROUND(testids2(i),2)
WHERE tid = n_id --Error 3
AND type = n_type
AND testid =testids1(i);
END IF;
END;
But while I am compiling procedure , I am getting multiple errors. I am very new to PL/SQL. Please let me know if I can retrieve calculated value as a Column in Bulk Collect? I am getting below errors in procedure:
Please let me know what is wrong here
Thanks
As I identified that the collection type that you are referring is not in scope in the procedure, might be you have declared globally. I modified your code get a try it once, hopefully, it works for you.
PROCEDURE test
IS
TYPE test1Tab IS TABLE OF testtable.testid%TYPE;
TYPE test2Tab IS TABLE OF number;
testids1 test1Tab; //Error 1 and Error 2
testids2 test2Tab;
BEGIN
IF NVL(v_mc,0) != 0 THEN
SELECT testid,
SUM(pct * NVL(cap,0))/v_mc lead
BULK COLLECT INTO testids1, testids2
FROM testtable a //Error 3
WHERE a.id = n_id
AND a.type =n_type
GROUP BY a.testid ORDER BY a.testid;
FORALL i IN testids1.FIRST..testids1.LAST
UPDATE testtable
SET LEAD = ROUND(testids2(i),2)
WHERE tid = n_id //Error 3
AND type = n_type
AND testid = testids1(i);
END IF;
END;
