begin
DECLARE ii INT;
DECLARE ki varchar(255);
DECLARE ulang int DEFAULT 1;
DECLARE hasil varchar(255) DEFAULT '';
DECLARE selesai INT DEFAULT FALSE;
DECLARE kursor CURSOR FOR
SELECT id_iklan, lokasi_kerja_utama
FROM iklan_lowongan_tb
WHERE status = 'Aktif';
DECLARE CONTINUE HANDLER FOR NOT FOUND SET selesai = TRUE;
DELETE FROM temp_lok_tb;
OPEN kursor;
read_loop: LOOP
FETCH kursor INTO ii, ki;
IF selesai THEN
LEAVE read_loop;
END IF;
WHILE (ulang < LENGTH(ki)) DO
IF SUBSTRING(ki, ulang, 1) <> '#' THEN
SET hasil = CONCAT(hasil, SUBSTRING(ki, ulang, 1));
ELSE
INSERT INTO temp_lok_tb (id_iklan, id_kota) VALUES(ii, hasil);
SET hasil = '';
END IF;
SET ulang = ulang+1;
END WHILE;
SET ulang = 1;

Answer 1

i think i can solve my problem myself.
this is my revision code, the result is true.
drop procedure if exists pecah_lokasi_sp;
create procedure pecah_lokasi_sp()
begin
DECLARE ii INT;
DECLARE ki varchar(255);
DECLARE ulang int DEFAULT 1;
DECLARE hasil varchar(255) DEFAULT '';
DECLARE selesai INT DEFAULT FALSE;
DECLARE jmlkarakter int;
DECLARE kursor CURSOR FOR
SELECT id_iklan, lokasi_kerja_utama
FROM iklan_lowongan_tb
WHERE status = 'Aktif';
DECLARE CONTINUE HANDLER FOR NOT FOUND SET selesai = TRUE;
DELETE FROM temp_lok_tb;
OPEN kursor;
read_loop: LOOP
FETCH kursor INTO ii, ki;
IF selesai THEN
LEAVE read_loop;
END IF;
SET jmlkarakter = LENGTH(ki) - LENGTH(REPLACE(ki, '#', '')) ;
WHILE (ulang <= jmlkarakter) DO
IF ulang = 1 THEN
INSERT INTO temp_lok_tb(id_iklan, id_kota) VALUES(ii, SUBSTRING_INDEX(ki,'#',1));
ELSE
INSERT INTO temp_lok_tb(id_iklan, id_kota) VALUES(ii, SUBSTRING_INDEX(SUBSTRING_INDEX(ki,'#', ulang),'#',-1));
END IF;
SET ulang = ulang+1;
END WHILE;
SET ulang = 1;
END LOOP read_loop;
CLOSE kursor;
select * from temp_lok_tb;
end;
