Question

DELIMITER $$
CREATE PROCEDURE `remove_schedule_duplicate` ()
BEGIN
BLOCK1 : BEGIN
DECLARE finished INTEGER DEFAULT 0;
DECLARE schedule_id CHAR(36);
DECLARE gamePk INTEGER;
DECLARE keep_entry TINYINT(1);
DECLARE scheduleDuplicate CURSOR FOR SELECT game_pk FROM schedule where is_active = 1 group by game_pk,home_team_id,away_team_id,venue_id having count(game_pk) > 1 limit 2;
DECLARE CONTINUE HANDLER FOR NOT FOUND SET finished = 1;
OPEN scheduleDuplicate;
get_schedule_duplicate: LOOP
FETCH scheduleDuplicate INTO gamePk;
IF finished = 1 THEN
LEAVE get_schedule_duplicate;
END IF;
**BLOCK2 : BEGIN
DECLARE block_finished INTEGER DEFAULT 0;
DECLARE blockDuplicate CURSOR FOR SELECT id FROM schedule where game_pk = gamePk and is_active = 1;
DECLARE CONTINUE HANDLER FOR NOT FOUND SET block_finished = 1;
OPEN blockDuplicate;
block_schedule_duplicate: LOOP
FETCH blockDuplicate INTO schedule_id;
IF block_finished = 1 THEN
LEAVE block_schedule_duplicate;
END IF;
IF keep_entry = 0 THEN
UPDATE schedule set is_active = 0 where id = schedule_id;
END IF;
END LOOP block_schedule_duplicate;
CLOSE blockDuplicate;
END BLOCK2;**
END LOOP get_schedule_duplicate;
CLOSE scheduleDuplicate;
END BLOCK1;
END

The problem is Innerloop first time execute well after that block_finished always be 1 so. always it quits the inner block.
How to resolve this issue. What i do ? Some one help me to resolve the issue.

I have Changed My Stored procedure like this:
DELIMITER $$
CREATE PROCEDURE `remove_schedule_duplicate`()
BEGIN
DECLARE finished INTEGER DEFAULT 0;
DECLARE schedule_id,temp CHAR(36) DEFAULT NULL;
DECLARE gamePk INTEGER;
DECLARE keep_entry TINYINT(1);
DECLARE scheduleDuplicate CURSOR FOR SELECT game_pk,id FROM schedule where game_pk in (SELECT game_pk FROM schedule where is_active = 1 group by game_pk,home_team_id,away_team_id,venue_id having count(game_pk) > 1) and is_active = 1 order by game_pk;
DECLARE CONTINUE HANDLER FOR NOT FOUND SET finished = 1;
OPEN scheduleDuplicate;
get_schedule_duplicate: LOOP
FETCH scheduleDuplicate INTO gamePk,schedule_id;
IF finished = 1 THEN
LEAVE get_schedule_duplicate;
END IF;
IF ((temp IS NULL) AND (gamePk IS NOT NULL)) OR ((temp IS NOT NULL) AND (temp <> gamePk)) THEN
SET temp = gamePk;
SET keep_entry = 1;
#ELSE IF temp IS NOT NULL AND temp = gamePk THEN
ELSE
SET keep_entry = 0;
END IF;
IF keep_entry = 0 THEN
UPDATE schedule set is_active = 0 where id = schedule_id;
END IF;
END LOOP get_schedule_duplicate;
CLOSE scheduleDuplicate;
END$$
