【中文标题】错误 1604 创建 MySQL 存储过程。 MySQL 版本 5.7.19【英文标题】:Error 1604 Creating MySQL Stored Procedure. MySQL Version 5.7.19 【发布时间】:2018-09-01 14:26:23 【问题描述】:我正在尝试将我过去编写的 SQL 存储过程转换为 mysql。这个错误给我带来了麻烦。
我正在使用 phpmyadmin 4.7.4
创建这个程序
我得到的错误是 SET userID = SELECT MAX(ID) + 1 FROM users
我还在代码中在它之前放置了一个标签,所以你们更容易找到。
输出的错误是:
MySQL said: Documentation
/#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 'SET userID = SELECT MAX(ID) + 1 FROM users;
-- Default to 1 if the table is em' at line 13
CREATE PROCEDURE uspAddUser(username VARCHAR(50), email VARCHAR(50), password VARCHAR(50), avatar VARCHAR(50))
BEGIN
DECLARE userID INTEGER;
BEGIN
ROLLBACK; -- Rollback transaction on error
END;
START TRANSACTION
-- Get the next highest ID and lock the table until the end of the transaction
<ERROR> -> SET userID = SELECT MAX(ID) + 1 FROM users;
-- Default to 1 if the table is empty
SET userID = COALESCE(userID, 1);
-- CREATE new record
INSERT INTO users(userID, username, email, password, avatar)
VALUES(ID, email, password, avatar, 1); -- 1 = Active
-- return ID to calling program
SELECT userID AS ID;
COMMIT;
END;//
如果你们想看的话,这是原始的 SQL 查询
GO
CREATE PROCEDURE uspAddTeam
@strTeam VARCHAR(50)
,@strMascot VARCHAR(50)
AS
SET NOCOUNT ON -- Report Only Errors
SET XACT_ABORT ON -- Rollback transaction on error
BEGIN TRANSACTION
DECLARE @intTeamID INTEGER
-- Get the next highest ID and lock the table until the end of the transaction
SELECT @intTeamID = MAX(intTeamID) + 1 FROM TTeams (TABLOCKX)
-- Default to 1 if the table is empty
SELECT @intTeamID = COALESCE(@intTeamID, 1)
-- CREATE new record
INSERT INTO TTeams(intTeamID, strTeam, strMascot, intTeamStatusID)
VALUES(@intTeamID, @strTeam, @strMascot, 1) -- 1 = Active
-- return ID to calling program
SELECT @intTeamID AS intTeamID
COMMIT TRANSACTION
GO
【问题讨论】:
【参考方案1】:你可以试试这个:
DROP PROCEDURE IF EXISTS `uspAddUser`;
DELIMITER //
CREATE PROCEDURE `uspAddUser` (username VARCHAR(50), email VARCHAR(50), password VARCHAR(50), avatar VARCHAR(50))
BEGIN
DECLARE `userID` BIGINT(20);
DECLARE EXIT HANDLER FOR SQLEXCEPTION
BEGIN
ROLLBACK;
END;
START TRANSACTION;
-- Get the next highest ID and lock the table until the end of the transaction
SET userID = (SELECT MAX(ID) + 1 FROM users);
-- Default to 1 if the table is empty
SET userID = COALESCE(userID, 1);
-- CREATE new record
INSERT INTO users(userID, username, email, password, avatar)
VALUES(ID, email, password, avatar, 1); -- 1 = Active
-- return ID to calling program
SELECT userID AS ID;
COMMIT;
END//
DELIMITER ;
问题
ID
的表是否设置为自增列?如果没有,请做..因为它会消除部分:
-- Get the next highest ID and lock the table until the end of the transaction
SET userID = (SELECT MAX(ID) + 1 FROM users);
【讨论】:
你是绝对正确的,我只是复制并粘贴存储过程,但是我完全不需要合并行。 我运行了您的查询并收到此错误。 #1337 - 游标或处理程序声明后的变量或条件声明。错误引用了上面所有代码,包括这一行 -> -- 获取下一个最高 ID 并锁定表直到事务结束 我刚刚尝试移动这一行 DECLARE userID INTEGER;到下面开始交易,什么都没有。以上是关于错误 1604 创建 MySQL 存储过程。 MySQL 版本 5.7.19的主要内容,如果未能解决你的问题,请参考以下文章
