带参数的MariaDB插入存储过程

Question

我将公司数据库从MySQL迁移到另一个托管公司，却不知道托管公司使用MariaDB，在尝试使用IN参数创建存储过程时，MariaDB将该参数视为columnn。 请参阅下面的存储过程代码，并显示以下错误：

    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))

     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;

    ***** AFTER RUNNING THE ABOVE CODE, MARIADB GAVE THIS ERROR :

    Error
    SQL query:

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

MySQL said: Documentation

#1054 - Unknown column 'withdrawalcode_p' in 'field list' 

列名是WithdrawalCode而不是'withdrawalcode_p'，'withdrawalcode_p'是传递给存储过程的参数，但是服务器将其视为字段名。 我与托管公司进行了交谈，他们说他们的数据库是MariaDB，而不是MySQL。 相同的代码在MySQL服务器中工作。

我将不胜感激这里提供的任何有用的帮助。

您忘记设置非默认定界符，并将过程主体包装到BEGIN / END ，这是必需的，因为它具有多个语句。

您遇到的情况是，使用主体START TRANSACTION创建的过程，其余过程被视为一组普通语句。 相反，尝试

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 ;
