MariaDB 插入带参数的存储过程

Question

我将我的公司数据库从 MySQL 迁移到另一家托管公司，但不知道该托管公司使用 MariaDB，在尝试使用我的 IN 参数创建存储过程时，MariaDB 将该参数视为列。请参阅以下带有错误的存储过程代码：

    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' 

列名称是 WithdrawalCode 而不是 'withdrawalcode_p'，'withdrawalcode_p' 是传递给存储过程的参数，但服务器将其视为字段名称。我和托管公司谈过，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。

我将感谢这里提供的任何有用的帮助。

您忘记设置非默认分隔符并将过程主体包装到BEGIN/ 中END，这是必要的，因为它有多个语句。

在您的情况下发生的情况是使用 body 创建的过程START TRANSACTION，其余部分被认为是一组普通语句。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 ;
