MySQL 不接受此过程。你能帮忙吗？

Question

CREATE PROCEDURE reset_xyz_autoincrement
BEGIN

  SELECT @max := MAX(ID)+ 1 FROM ABC; 

  PREPARE stmt FROM 'ALTER TABLE XYZ AUTO_INCREMENT = ?'
  EXECUTE stmt USING @max 

  DEALLOCATE PREPARE stmt;

END $$

我从这里获取了代码: How to Reset an MySQL AutoIncrement using a MAX value from another table?

这是 MySQL 输出:

#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 'BEGIN

  SELECT @max := MAX(ID)+ 1 FROM ABC' at line 2

试试这个

     CREATE PROCEDURE reset_xyz_autoincrement
          (username varchar(64),password varchar(64))     // here you use your columns
      BEGIN

编辑:

试试这个

     DROP PROCEDURE IF EXISTS reset_xyz_autoincrement;
     CREATE PROCEDURE reset_xyz_autoincrement (userid INT)
      BEGIN
