mysql - 无法创建包含union的视图

Question

我有一个mysql查询，它使用union将多个查询连接到一个结果集中。查询工作正常。

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

我的查询完美无缺：

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：

查询全部来自设计糟糕的表格，因此不应存在格式化或排序规则问题。是否可以针对联合查询创建视图？

感谢任何建议。

从视图定义中删除括号。您已点击此服务器bug。
