好了，如u說，SQL Server 2005中，我會告訴你的實現使用rownumber。假設： 1.）基本組應該是Id。 ID 1和ID 2的帳戶不應位於同一行。

解決方案與模擬數據：

SELECT ID, 
     Max(Case When OrderCaluse = 0 Then Account Else NULL END) AS Account1, 
     Max(Case When OrderCaluse = 1 Then Account Else NULL END) AS Account2 
FROM 
( 
    Select ID, 
      Account, 
      (RowNum+1)/2 As GroupClause, 
      (RowNum+1)%2 as OrderCaluse 
    FROM 
    (
     Select *, 
       ROW_NUMBER() Over (Partition by Id order by account) As RowNum 
     FRom 
     (
      Select 1 as Id, 25 as Account 
      Union ALL 
      Select 1, 31 
      Union ALL 
      Select 1, 35 
      Union ALL 
      Select 1, 44 
      Union ALL 
      Select 1, 50 
      Union ALL 
      Select 1, 59 
     ) AS UserAccount 
    ) AS T 
) AS T1 
Group By Id,GroupClause 

結果：

1 25 31 
1 35 44 
1 50 59 

希望它能幫助。爲了您的使用，只需刪除Inner temp表UserAccount並使用您的物理表。
