我创建了以下存储过程，并且在我的生活中，我不明白为什么会出现上述错误。我尝试移动END //斜线越来越远，我添加了一个;之前 // 我做错了什么？

DELIMITER //

非常感谢你们这么快帮助和帮助。

我在多次搜索后发现MySQL错误1604是语法错误。所以我开始删除代码，直到找到问题为止。

这两行：

    IF RowsExtractedMaxID IS NULL THEN SET RowsExtractedMaxID:=0;
    IF RowsInsertedMaxID  IS NULL THEN SET RowsInsertedMaxID:=0;

不知何故在语法上不起作用。老实说，我不知道为什么。我继续使用变量将它们包含在主SELECT语句中。

    SELECT IFNULL(RowsExtractedCnt = COUNT(*), 0), IFNULL(RowsExtractedMaxID = MAX(ID), 0)
            FROM tbl10760Raw 
            WHERE tbl10760Raw.DeviceReportedTime = tbl10760Raw.ReceivedAt 
            AND tbl10760Raw.DeviceReportedTime 
            BETWEEN TableWindowPointer AND TableStartPointer;

    SELECT IFNULL(RowsInsertedMaxID = (SELECT MAX(RowsExtractedMaxID10760) FROM etlETLEventLog), 0);

我希望有一天会遇到类似问题的人。
