结合2个查询的结果

Question

美好的一天， 我是这个论坛的新手，我很高兴因为我是Sql的新手。 如何使用Union all或任何方式组合这两个查询的结果。进行查询A是否很长

查询 （A）

select 
    a.SiteName,
    a.Hostname,
    a.FreeSpace,
    a.FreeSpacePerc,

    cast(([SystemFreeSpacePercentage]*100) as nvarchar(10)) + '% (' + [SystemDriveName] + ':)' as FreeSpacePerc,
    case when [SystemFreeSpace] <= 20 then 'RED' else 'BLACK' end as Color,
    Createdon
