Question

运行此查询时，我收到以下错误，我不明白。我现在已加入行，是否存在某些我应该知道的限制或者我是否缺少简单错误？这是错误：

#1235 - This version of MySQL doesn't yet support 'LIMIT & IN/ALL/ANY/SOME subquery'

这是我想要运行的查询：

 SELECT t.* 
FROM tasks t 
LEFT JOIN users u ON u.user_id = 1 
WHERE task_id = '677' 

AND createdby IN(
    (SELECT u1.user_id FROM users u1 WHERE u1.user_team = u.user_team 
     AND taskrspnsble IN(
        (SELECT u2.user_id FROM users u2 WHERE u2.user_role <= u.user_role)
    ))
)

由于萨蒂的回答，我想出来了：

SELECT t.* 
FROM tasks t 
LEFT JOIN users u ON u.user_id = 1 
WHERE task_id = '677' 

AND createdby IN(
    (SELECT u1.user_id FROM users u1 WHERE u1.user_team = u.user_team 
     AND taskrspnsble IN(
        (SELECT u2.user_id FROM users u2 WHERE u2.user_role <= u.user_role)
    ))
)

为什么这个版本的MySQL还没有支持＆＃39; LIMIT＆amp; IN / ALL / ANY / SOME子查询＆＃39;
