Question

I am trying to translate a SQL stored procedure I have written in the past to MySQL. This error is giving me trouble.

I am using phpmyadmin 4.7.4 to create this procedure The error I am getting is at SET userID = SELECT MAX(ID) + 1 FROM users I have also placed a tag before it in the code so it is easier for you guys to find.

The error that is outputted is:

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;//

This is the original SQL query if you guys want to see that at all

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

你可以试试这个：

registration_type_id

问题（S）

将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 ;的表格设置为自动增量列吗？如果没有，请做..因为它将消除部分：
```
ID
```
