我正在phpmyadmin中编写存储过程,但我在Update
语句附近收到语法错误。但是,如果我将更新语句放在if语句中,而不是所有错误都已解决。
问:为什么外部更新语句会导致错误?
CREATE DEFINER=`root`@`localhost` PROCEDURE `tbl_people_update`(IN `p_Id` INT, IN `p_Name` VARCHAR(150), IN `p_Mobile_Number` VARCHAR(100))
IF CHAR_LENGTH(p_Mobile_Number) <= 0 THEN
SET p_Mobile_Number = '12345';
END IF;
UPDATE tbl_people
SET
Name=p_Name,
Mobile_Number = p_Mobile_Number
WHERE
Id=p_Id;
错误如下:
#1064 - 您的SQL语法出错;查看与MariaDB服务器版本对应的手册,以获取正确的语法 'UPDATE tbl_people SET Name = p_Name,Mobile_Number =附近 p_Mobile_Number'第5行'

你忘了重新定义分隔符,试试这个:
delimiter ||
CREATE DEFINER=`root`@`localhost` PROCEDURE `tbl_people_update`(IN `p_Id` INT, IN `p_Name` VARCHAR(150), IN `p_Mobile_Number` VARCHAR(100))
IF CHAR_LENGTH(p_Mobile_Number) <= 0 THEN
SET p_Mobile_Number = '12345';
END IF;
UPDATE tbl_people
SET
Name=p_Name,
Mobile_Number = p_Mobile_Number
WHERE
Id=p_Id;
||
delimiter ;

DELIMITER $$
CREATE DEFINER=`root`@`localhost` PROCEDURE `tbl_people_update`(IN `p_Id` INT, IN `p_Name` VARCHAR(150), IN `p_Mobile_Number` VARCHAR(100))
BEGIN
IF CHAR_LENGTH(p_Mobile_Number) <= 0 THEN
SET p_Mobile_Number = '12345';
END IF;
UPDATE tbl_people
SET
Name=p_Name,
Mobile_Number = p_Mobile_Number
WHERE
Id=p_Id;
END$$
DELIMITER ;
尝试以上代码。
希望这会对你有所帮助。
