error＃1349 view的select子句在from子句中包含一个子查询

Question

这是我的代码，

Select CAST.first_name, CAST.last_name, `directors winning movies list`.castID, count(*) AwardsWon
From `directors winning movies list`, CAST  
WHERE `directors winning movies list`.castID = CAST.castID
Group By `directors winning movies list`.castID
Having count(*)
    = (Select Max(cnt)
       From (Select count(*) cnt
             From `directors winning movies list`
             Group By `directors winning movies list`.castID) z)

查询本身正确执行，但是当我尝试创建一个视图并保存它时，我得到错误＃1349视图的select子句在from子句中包含一个子查询。有谁知道如何解决这个问题？

Answer 1

MySQL不允许使用子查询创建视图。 可能的解决方法是为每个子查询创建单独的视图。

例如：

CREATE VIEW movies_view AS
SELECT COUNT(*) cnt
             FROM `directors winning movies list`
             GROUP BY `directors winning movies list`.castID) z)

---

CREATE VIEW movies_view_count AS
SELECT MAX(cnt) from movies_view

调用主查询中的movies_view_count，它应该有效。
