MySQL中的錯誤調用過程：錯誤代碼：2013。查詢期間與MySQL服務器的連接斷開

Question

我需要有關MySQL的幫助，當我調用特定過程時，Workbench失去連接，MySQL80 Windows服務被捕！

我已經嘗試在編輯->首選項-> SQL編輯器-> DBMS連接讀取超時（以秒為單位）上設置更高的參數（600）。

我不知道是否有幫助，但這是我的程序：

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 
    FROM topics 
    WHERE edit_time > v_edit_time 
    LIMIT v_scraped_topics 
    OFFSET v_offset;

    DELETE FROM logs 
    WHERE step_time > v_edit_time
    AND parent_id = p_forum_id
    AND object_id IN (SELECT topic_id FROM topic_ids);

    DELETE FROM torrents_tmp 
    WHERE forum_id = p_forum_id
    AND topic_id IN (SELECT topic_id FROM topic_ids);

    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 ;

如果我分別調用所有查詢（顯然具有相同的參數），我沒有任何問題！

Answer 1

您的my.ini [mysqld]部分要考慮的建議

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

這些更改對於實現實例的穩定性是必需的。

審查您的程序，將嘗試在星期五下午之前對您的程序發表評論。 某些請求的數據僅在Linux系統上可用。 要確定計算機上的RAM，請右鍵單擊任務欄左側的“窗口”圖標，然后單擊“系統”，您應該看到服務器上有多少RAM。

我通過更新DBMS解決了！ 這是我的MySQL版本的錯誤！
