在 MySQL 中创建存储过程时出错，Error#1064

Question

我很难创建存储过程。 我曾尝试根据堆栈溢出的其他条目更改一些内容，但没有帮助。

select version(); 返回5.7.31-0ubuntu0.16.04.1万一。

这是查询：

DELIMITER $$
CREATE
PROCEDURE forceSubscribeToNode(IN node_id_var INT)
BEGIN
  INSERT
INTO
  xf_forum_watch(
    user_id,
    node_id,
    notify_on,
    send_alert,
    send_email
  )
SELECT
  user_id,
  node_id_var AS node_id,
  "thread" AS notify_on,
  1 AS send_alert,
  1 AS send_email
FROM
  xf_user
WHERE
  user_group_id NOT IN(
      1, 18, 40
  )
  ON DUPLICATE KEY
UPDATE
  send_alert = 1,
  send_email = 1,
  notify_on = CASE WHEN notify_on IS NULL OR notify_on = '' THEN 'thread' ELSE notify_on END
END $$
DELIMITER ;

这是错误：

#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 'END' at line 30

（第 18 行是“send_email = 1”，

对于上下文、搜索引擎和未来参考：

这将用于论坛软件 Xenforo 2.1 强制订阅用户到某些节点，如类别和子论坛。

Answer 1

所以看来我忘了添加一个; 在第一个END之后有一个空格

DELIMITER $$
CREATE
PROCEDURE forceSubscribeToNode(IN node_id_var INT)
BEGIN
  INSERT
INTO
  xf_forum_watch(
    user_id,
    node_id,
    notify_on,
    send_alert,
    send_email
  )
SELECT
  user_id,
  node_id_var AS node_id,
  "thread" AS notify_on,
  1 AS send_alert,
  1 AS send_email
FROM
  xf_user
WHERE
  user_group_id NOT IN(
      1, 18, 40
  )
  ON DUPLICATE KEY
UPDATE
  send_alert = 1,
  send_email = 1,
  notify_on = CASE WHEN notify_on IS NULL OR notify_on = '' THEN 'thread' ELSE notify_on END ;
END $$

DELIMITER ;
