Question

In SQL Server I wrote a query to count specific columns but I am displaying all count in more than one table, it’s not a good way to show. How to display all tables in single row in new table?

     select COUNT(s.AssetSubType) as 'PhysicalServers' from Asset s
      where s.CompanyId = @companyId and
            s.AssetType = 1 and
            s.AssetSubType = 4 

   select COUNT(s.AssetSubType) as 'WorkStations' from Asset s
      where s.CompanyId = @companyId and
            s.AssetType = 1 and
            s.AssetSubType = 1 or s.AssetSubType = 3    

 select COUNT(s.AssetSubType) as 'EmailOnlyUsers' from Asset s
      where s.CompanyId = @companyId and
            s.AssetType = 2 and 
            s.AssetSubType = 16             

 select COUNT(s.OperatingSystem) as '#OfMSServers' from Asset s
      where s.CompanyId = @companyId and
            s.AssetType = 1 and
            s.AssetSubType = 4 and 
            s.OperatingSystem = 1 

 select COUNT(s.OperatingSystem) as '#OfLinuxServers' from Asset s
      where s.CompanyId = @companyId and
            s.AssetType = 1 and
            s.AssetSubType = 4 and 
            s.OperatingSystem = 2

Something like this should work for you

select sum(case when s.AssetType = 1 and 
                     s.AssetSubType = 4 
                then 1 end) as 'PhysicalServers',
       sum(case when s.AssetType = 1 and 
                     (s.AssetSubType = 1 or s.AssetSubType = 3) 
                then 1 end) as 'WorkStations',
       sum(case when s.AssetType = 2 and 
                     s.AssetSubType = 16 
                then 1 end) as 'EmailOnlyUsers',
       sum(case when s.AssetType = 1 and 
                     s.AssetSubType = 4 and 
                     s.OperatingSystem = 1 
                then 1 end) as '#OfMSServers',
       sum(case when s.AssetType = 1 and 
                     s.AssetSubType = 4 and 
                     s.OperatingSystem = 2 
                then 1 end) as '#OfLinuxServers'
from Asset s
where s.CompanyId = @companyId
