mysql - MariaDB 不在过程中执行插入

Question

我正在使用 MySQL - 实际上是来自 PHPMyAdmin 的 MariaDB - 并试图在存储过程中编写插入，出于明显的(安全)原因，这是不允许的。

我尝试使用 GRANT EXECUTE ON PROCEDURE 语句更改权限。

GRANT EXECUTE ON PROCEDURE test.putDataInFull TO 'root'@'localhost' 

我真的在这里碰壁了，有什么想法吗？

编辑:

DELIMITER //
CREATE PROCEDURE putDataInFull (IN matchid INT(11))
BEGIN
  DECLARE koula int(11);
  DECLARE c     varchar(255);
  SET @koula = matchid;
  SET @c := concat('insert into log (match_id, comment) values (?,\'inPUtDataWeTrtust\');');

  DECLARE EXIT HANDLER FOR SQLEXCEPTION
       BEGIN
         SELECT CONCAT(@c, ' is not valid');
       END;
  PREPARE stmt FROM @c;
  EXECUTE stmt USING @koula;
  DEALLOCATE PREPARE stmt;
END //
DELIMITER ;

附注这不是一个生产项目，只是为了好玩，所以我真的不关心安全性。

您可以使用变量创建插入。没有必要创建魔术字符串。在这里你得到另一个例子 an other stackoverflow question :

DELIMITER $$

CREATE  PROCEDURE ADD_WITHDRAWAL_A(IN withdrawalcode_p VARCHAR(25), IN id_p VARCHAR(8), IN amount_p VARCHAR(12), IN datewithdrawn_p VARCHAR(35), IN approved_p VARCHAR(8))
BEGIN

     START TRANSACTION;

     INSERT INTO Withdrawals(WithdrawalCode, IDD, Amount, DateWithdrawn, Approved) 
     VALUES (withdrawalcode_p, id_p, amount_p, datewithdrawn_p, approved_p);

     UPDATE account SET AccountBalance = AccountBalance - amount_p WHERE IDD = id_p LIMIT 1;

     COMMIT;

END $$

DELIMITER ;
