Question

我在Mysql数据库中有一个存储过程，如下所示：

DELIMITER $$

USE `vboard_75`$$

DROP PROCEDURE IF EXISTS `sp_LongWaitCall`$$
CREATE DEFINER=`root`@`localhost` PROCEDURE `sp_LongWaitCall`()

BEGIN


    UPDATE cdr SET cdr.CallStatus='DISCONNECTED',cdr.EndTime=NOW() WHERE cdr.CallStatus='RINGINGIN' 
    AND MINUTE(DATEDIFF(cdr.StartTime,NOW())) >=7;

    DECLARE _StatVal FLOAT;
    DECLARE _DevID INT;
    DECLARE Record_Fetch INT DEFAULT 0;
    DECLARE crsr_Board CURSOR FOR
    SELECT  IFNULL(MAX(SECOND(DATEDIFF(CDR.StartTime, IFNULL(CDR.EndTime, NOW())))), 0) AS LRT,vw_Boards_Ext.boardid
    FROM    vw_Boards_Ext RIGHT OUTER JOIN
                boards ON vw_Boards_Ext.boardid = boards.boardid LEFT OUTER JOIN
                CDR ON vw_Boards_Ext.Ext = CDR.DDI AND 
                STR_TO_DATE(CONCAT(boards.ResetDate,' ',boards.ResetTime),'%m/%d/%Y %H:%i') < CDR.timestamp
    AND CDR.CallStatus='RINGINGIN'
    GROUP BY vw_Boards_Ext.boardid;

    DECLARE CONTINUE HANDLER FOR NOT FOUND SET Record_Fetch = 1;
    OPEN crsr_Board;
    FETCH crsr_Board INTO _StatVal, _DevID;
    WHILE Record_Fetch = 0 DO

        UPDATE stat_values AS sv SET sv.StatValue = _StatVal,sv.timestamp= NOW() 
        WHERE sv.itemId = _DevID AND sv.itemType = 'boards' AND sv.StatId = 3;
        FETCH crsr_Board INTO _StatVal, _DevID;

    END WHILE;
    CLOSE crsr_Board;
    DEALLOCATE PREPARE crsr_Board;
END$$

DELIMITER ;

错误：

查询：CREATE DEFINER = root @ localhost程序sp_LongWaitCall（）BEGIN update cdr set cdr.CallStatus ='DISCONNECTED'，cdr.EndTime = n ...

错误代码：1064
  您的SQL语法有错误;检查与您的MariaDB服务器版本对应的手册，以便在'DECLARE _StatVal FLOAT附近使用正确的语法;       DECLARE _DevID INT;       在第8行DECLARE Record_Fetch INT DEFAULT 0'

This文档指的是在DECLARE和CURSORS创建任何HANDLERS和BEGIN... END之前的BEGIN... END语句，您正在关注但不在开头UPDATE区块。
