MySQL存储过程错误

Question

我试图在存储的mySQL过程中使用if语句，但是当我尝试在mySQL工作台中创建它时，出现此错误ERROR 1064: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'database'.'table' WHERE date=dateIn; ERROR 1064: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'database'.'table' WHERE date=dateIn; 。

这是代码：

DELIMITER $$

CREATE DEFINER=`rates_d_db` PROCEDURE `byDate`(in dateIn VARCHAR(255),in action VARCHAR(255))
BEGIN

IF action = "edit" THEN EDIT `database`.`table` WHERE date=dateIn;

ELSE SELECT * FROM `database`.`table` WHERE date=dateIn;

END IF;

END$$

我是存储过程的新手，所以这可能是一个非常愚蠢的错误。

提前感谢！

Answer 1

这是您程序的正确版本

DELIMITER $$

CREATE DEFINER=`rates_d_db` PROCEDURE `byDatee`(in dateIn VARCHAR(255),in action VARCHAR(255))
       BEGIN
           IF action = "edit" THEN 
                -- I used select below as i don't know what you want in edit either alter table or update table
               SELECT * FROM `database`.`table` WHERE date=dateIn;    
           ELSE
                SELECT * FROM `database`.`table` WHERE date=dateIn;
           END IF;
END $$

date是mySQL中的保留字 。 您还必须将其包装在反引号中。
