Question

我是sql的新手，我的大部分培训都是在MSSQL中，但是我正在MYSQL中学习。我有一个存储过程给我一个问题。我将分隔符设置为//.

CREATE PROCEDURE AddComment
(
    name varchar(50),
    emailAddress varchar(50),
    Comments text
)
BEGIN
DECLARE ComName varchar(50);
DECLARE ComID int;


SELECT name into ComName;

SELECT ID into ComID from Commenters WHERE names = ComName;

if ComID = NULL
    BEGIN
        INSERT INTO COMMENTERS ('names', 'emailAddresses') values (name,   emailAddress);
        SELECT ID into ComID from Commenters WHERE names = ComName;
    END

    INSERT INTO COMMENTS ('commentersID', 'Comments') values (ComID, Comments);

END;
//

修改

这就是我现在所拥有的：

CREATE PROCEDURE AddComment
(
    Username varchar(50),
    UseremailAddress varchar(50),
    UserComment text
)
BEGIN
DECLARE ComName varchar(50);
DECLARE ComID int;


SELECT Username into ComName;

SELECT ID into ComID from Commenters WHERE names = ComName;

if ComID = NULL
    BEGIN
        INSERT INTO COMMENTERS(names,emailAddresses) values (Username, UseremailAddress);
        SELECT ID into ComID from Commenters WHERE names = ComName;
    END

    INSERT INTO COMMENTS(commentersID, Comments) values (ComID, UserComment);


END;
//

我得到的错误是：

错误1064（42000）：您的SQL语法有错误;检查与MySQL服务器版本对应的手册，以便在'BEGIN INSERT INT附近使用正确的语法 O COMMENTERS（姓名，电子邮件地址）值（用户名，第1行的Useremail'

任何想法？

Answer 1

您正在编写插入语句中反转的列名和值。

应该是

 INSERT INTO COMMENTERS (name, emailAddress) values ('names', 'emailAddresses') ;
