在 MySQL 中调用过程时出错：错误代码：2013。查询期间与 MySQL 服务器失去连接
Error calling procedure in MySQL: Error Code: 2013. Lost connection to MySQL server during query
我需要有关 MySQL 的帮助，当我调用特定程序时 Workbench 失去连接并且 MySQL80 Windows 服务被阻止！
我已经尝试在编辑 -> 首选项 -> SQL 编辑器 -> DBMS 连接读取超时（以秒为单位）上设置更高的参数 (600)。
我不知道它是否有帮助，但这是我的程序：
DELIMITER //
DROP PROCEDURE IF EXISTS drop_unfinished //
CREATE PROCEDURE drop_unfinished(
OUT p_return INT,
IN p_forum_id INT
)
COMMENT 'Drops all unscraped batches for the given forum'
READS SQL DATA
BEGIN
DECLARE v_limit INT;
DECLARE v_offset INT;
DECLARE v_scraped_batches INT;
DECLARE v_scraped_topics INT;
DECLARE v_edit_time DATETIME;
DECLARE v_start_time DATETIME;
DECLARE EXIT HANDLER FOR SQLEXCEPTION SET p_return = -1;
SELECT scraped_topics, scraped_batches, edit_time
INTO v_scraped_topics, v_scraped_batches, v_edit_time
FROM dashboard_view
WHERE forum_id = p_forum_id;
SET v_limit = 25;
SET v_offset = IF(v_scraped_batches = 1, 0, v_limit * v_scraped_batches);
CREATE TEMPORARY TABLE
IF NOT EXISTS topic_ids
SELECT topic_id

LIMIT v_scraped_topics
OFFSET v_offset;
DELETE FROM logs

DELETE FROM torrents_tmp

DELETE FROM ed2k_links_tmp
WHERE forum_id = p_forum_id
AND topic_id IN (SELECT topic_id FROM topic_ids);
DELETE FROM posts_tmp
WHERE forum_id = p_forum_id
AND topic_id IN (SELECT topic_id FROM topic_ids);
COMMIT;
DROP TEMPORARY TABLE topic_ids;
SET p_return = 0;
END
//
DELIMITER ;
如果我分别调用所有查询（显然使用相同的参数）我没有任何问题！

my.ini [mysqld] 部分要考虑的建议
read_rnd_buffer_size=256K # from 1 - pretty astounding you run at all
read_buffer_size=128K # from 8K - for a more reasonable limit
thread_cache_size=40 # from 10 to prepare for growth
innodb_io_capacity=1600 # from 200 to allow higher IOPS
max_connections=50 # from default of 151 until you have more activity
innodb_buffer_pool_size=256M # from 8M likely you will get to innodb tables soon
这些更改对于实现您的实例的稳定性是必要的。
