存储过程不插入任何数据

Question

我编写了以下存储过程来插入批量数据列表。存储过程成功编译但不插入任何条目。我对存储过程很新，不知道我错过了什么。任何人都可以评论：

这里我们尝试将URL列表和pe_tier添加到数据库中

CREATE DEFINER=`root`@`localhost` PROCEDURE `KKEventsInBulk`(
IN url varchar(4096),
IN emailArchivePath varchar (4096),
IN orgId int,
IN feedId int,
IN normalized_pattern_string varchar (4096),
IN uuid varchar(4096),
IN pe_tier int)
BEGIN
DECLARE p2 varchar(4000);
 DECLARE EXIT HANDLER FOR SQLEXCEPTION
       BEGIN
             ROLLBACK;
              GET DIAGNOSTICS CONDITION 1
              p2 = MESSAGE_TEXT;
              SET p2=concat('Error ',p2);
            SELECT p2;
        END;
        INSERT INTO kk_pattern (uuid, nomalized_pattern_string) values(uuid, normalized_pattern_string);
    WHILE url != '' DO
       IF EXISTS(SELECT 1 FROM url_event_detail ue where ue.url=url) THEN
                 INSERT INTO kk_event_detail(eventID,email_archive_path, patternID) values((select event_id from url_event_detail), email_archive_path, 
                 (select id from pe_pattern p where p.normalized_pattern_string=normalized_pattern_string));
       ELSE 
          BEGIN
                INSERT INTO kk_waiting_on_ce(url, pe_tier, email_archive_path, pattern_id, org_id, feed_id)values
                (url, pe_tier, email_archive_path, 
                 (select id from pe_pattern p where p.normalized_pattern_string = normalized_pattern_string and p.uuid=uuid ),
                 org_id, feed_id);
        END;
        END IF;
    END WHILE;
    COMMIT;
END
