Question

Mysql語法錯誤我不斷收到此刪除錯誤。 Mysql版本是5.0.77。我想不出任何其他問題。我甚至創建了一個臨時表來避免在select中修改表的問題。 :(

ERROR 1064（42000）：你在你的SQL語法錯誤;檢查對應於你的MySQL服務器版本使用附近的「WHERE e.eid IN （SELECT * FROM 正確的語法手冊（SELECT w.eid FROM」在行3

具有以下刪除

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

嘗試從你從刪除的表失去別名：

DELETE FROM emp2 
WHERE eid IN (SELECT ... 

Answer 2

這可能工作：

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 
    ) 

究竟是你想刪除哪個？
