Question

我通过此删除不断收到此错误。 Mysql版本是5.0.77。我想不出任何其他问题。我甚至创建了一个临时表来避免修改select中的表的问题。：（

错误1064（42000）：您的SQL语法有错误;检查与您的MySQL服务器版本对应的手册，以便在'WHERE e.eid IN附近使用正确的语法（选择 * FROM（SELECT w.eid 从'第3行

使用以下删除

DELETE
FROM emp2 e
WHERE e.eid IN
       (SELECT *
       FROM    (SELECT w.eid
               FROM    works2 w,
                       emp2 e2,
                       dept2 d
               WHERE   w.did = d.did
               AND     d.managerid = e2.eid
               AND     e.salary > e2.salary
               )
               AS temp1
       );

Answer 1

尝试从您要删除的表中删除别名：

DELETE FROM emp2
WHERE eid IN (SELECT ...

Answer 2

这可能有效：

DELETE e
FROM emp2 e
  JOIN works2 w
    ON w.eid = e.eid 
  JOIN dept2 d
    ON w.did = d.did
  JOIN emp2 e2
    ON d.managerid = e2.eid
WHERE e.salary > e2.salary

或EXISTS版本：

DELETE FROM emp2 e
WHERE EXISTS
      ( SELECT *
        FROM   works2 w,
               emp2 e2,
               dept2 d
        WHERE  w.did = d.did
          AND  d.managerid = e2.eid
          AND  e.salary > e2.salary
          AND  w.eid = e.eid
      )

你究竟要删除什么？

使用= any或in的Mysql语法错误
