mysql - 无法创建包含联合的视图

Question

我有一个 mysql 查询，它使用联合将多个查询连接到一个结果集中。查询完美运行。

当我想使用相同的查询来创建视图时，我会收到一条错误消息：

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 'union select hulaminloadnumber2,deliveryid,drop1customer from localjhb where hul' at line 2

我的完美查询是：

select hulaminloadnumber1,deliveryid,drop1customer from localjhb where hulaminloadnumber1>0
union
select hulaminloadnumber2,deliveryid,drop1customer from localjhb where hulaminloadnumber2>0
union
select hulaminloadnumber3,deliveryid,drop1customer from localjhb where hulaminloadnumber3>0
union
select hulaminloadnumber4,deliveryid,drop1customer from localjhb where hulaminloadnumber4>0
union
select hulaminloadnumber5,deliveryid,drop1customer from localjhb where hulaminloadnumber5>0

我创建视图的查询是：

create view View_LoadvsCustomer as (
select hulaminloadnumber1,deliveryid,drop1customer from localjhb where hulaminloadnumber1>0
union
select hulaminloadnumber2,deliveryid,drop1customer from localjhb where hulaminloadnumber2>0
union
select hulaminloadnumber3,deliveryid,drop1customer from localjhb where hulaminloadnumber3>0
union
select hulaminloadnumber4,deliveryid,drop1customer from localjhb where hulaminloadnumber4>0
union
select hulaminloadnumber5,deliveryid,drop1customer from localjhb where hulaminloadnumber5>0)

这会在 PHPMyadmin 中产生以下错误：

所有查询都来自设计不佳的表，因此不应存在格式或排序问题。可以针对联合查询创建视图吗？

感谢任何建议。

周末愉快， 瑞恩

从视图定义中删除括号。您已访问此服务器bug。
