mysql - Group by select 基于 OR 条件

Question

将 UNION 与两个选择查询一起使用后，我得到以下结果

UserId    Name    Status
------   ------  --------
1   User1   Active
2   User2   Active
1   User1   InActive
3   User3   InActive

但预期的结果是

UserId Name Status
---------------------
1   User1   Active
2   User2   Active
3   User3   InActive

我需要的是，我想按列 Id 分组，如果有任何一个结果是事件的，则状态为事件。如何为此形成 SQL 查询？

任何人都可以建议查询以下任何一个数据库吗？

1. MSSQL
2. 甲骨文
3. MySQL
4. PostgreSQL

编辑:

这是我在 PostgreSQL 中尝试过的查询

(SELECT DISTINCT User.Id,User.DisplayName,AppAccessToUsers.IsActive='1' AND User.IsActive='1' AS IsStatusActive 
FROM Applications Left JOIN AppAccessToUsers ON (Applications.Id=AppAccessToUsers.ApplicationId) 
Left JOIN User ON (AppAccessToUsers.UserId=User.Id) WHERE Applications.ClientId='e7e66c1b-b3b8-4ffb-844b-fc4840803265') 
UNION 
(SELECT DISTINCT User.Id,User.DisplayName,AppAccessToGroups.IsActive='1' AND Group.IsActive='1' AND UserGroup.IsActive='1' AND User.IsActive='1' AS IsStatusActive 
FROM Applications Left JOIN AppAccessToGroups ON (Applications.Id=AppAccessToGroups.ApplicationId) 
Left JOIN Group ON (AppAccessToGroups.GroupId=Group.Id) Left JOIN UserGroup ON (Group.Id=UserGroup.GroupId) 
Left JOIN User ON (UserGroup.UserId=User.Id) WHERE Applications.ClientId='e7e66c1b-b3b8-4ffb-844b-fc4840803265')

使用这个查询，

SELECT  UserId
        ,Name
        ,CASE WHEN min(status) = 'Active' THEN 'Active' ELSE 'InActive' END
FROM users GROUP BY UserId,Name
