例

Declare @SQL varchar(max) = '' 
Set @SQL = Stuff((Select Distinct ',' +QuoteName('C'+cast(RN as varchar(25))) 
            +','+QuoteName('P'+cast(RN as varchar(25))) 
        From (Select Distinct RN=Row_Number() over (Order By Pays) From YourTable) A 
        Order by 1 For XML Path('')),1,1,'') 

Set @SQL = ' 
Select ' + replace(replace(@SQL,'[P','Pays=[P'),'[C','Count=[C') + ' 
From (
     Select B.* 
     From (
       Select *,RN = Row_Number() over (Order By Pays) 
       From YourTable 
       ) A 
     Cross Apply (values (''P''+cast(A.RN as varchar(25)),A.Pays) 
          ,(''C''+cast(A.RN as varchar(25)),cast(A.Count as varchar(50))) 
        ) B (Item,Value) 
    ) A 
Pivot (max(value) For [Item] in (' + @SQL + ')) p' 
Exec(@SQL);

如果有幫助，生成的SQL是這樣的：你

Select Count=[C1],Pays=[P1],Count=[C2],Pays=[P2],Count=[C3],Pays=[P3],Count=[C4],Pays=[P4] 
From (
     Select B.* 
     From (
       Select *,RN = Row_Number() over (Order By Pays) 
       From YourTable 
       ) A 
     Cross Apply (values ('P'+cast(A.RN as varchar(25)),A.Pays) 
          ,('C'+cast(A.RN as varchar(25)),cast(A.Count as varchar(50))) 
        ) B (Item,Value) 
    ) A 
Pivot (max(value) For [Item] in ([C1],[P1],[C2],[P2],[C3],[P3],[C4],[P4])) p
