これは達成するのが簡単なことのように思えますが、望ましい結果を得るために正しく考えているかどうかはわかりません. 私はピボットを使用していますが、それとペアになっている何かが必要だと思います。

各クライアントの毎月の請求書を含む請求書テーブルがあります。多くても、クライアントは毎月 1 通ずつ、年間 12 通の請求書を受け取ります。

+----------+-------+-------+--------------+--------------+--------------+
| ClientID | Month | Year  | ColumnValue1 | ColumnValue2 | ColumnValue3 |
+----------+-------+-------+--------------+--------------+--------------+
|        1 |     1 |  2012 |           20 |           30 |           50 |
|        1 |     2 |  2012 |           25 |           35 |           40 |
|        2 |     1 |  2012 |           28 |           38 |           48 |
+----------+-------+-------+--------------+--------------+--------------+

今、各クライアントに基づいて以下のようなリストを作成したいと考えています。各月の列があります。したがって、クライアント 1 は次のようになります。

+--------------+----+----+---+---+---+---+---+---+---+----+----+----+-------+
|  ColumnName  | 1  | 2  | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 | Total |
+--------------+----+----+---+---+---+---+---+---+---+----+----+----+-------+
| ColumnValue1 | 20 | 25 | 0 | 0 | 0 | 0 | 0 | 0 | 0 |  0 |  0 |  0 |   45  |
| ColumnValue2 | 30 | 35 | 0 | 0 | 0 | 0 | 0 | 0 | 0 |  0 |  0 |  0 |   65  |
| ColumnValue3 | 50 | 40 | 0 | 0 | 0 | 0 | 0 | 0 | 0 |  0 |  0 |  0 |   90  |
+--------------+----+----+---+---+---+---+---+---+---+----+----+----+-------+

これを試して

Declare @t Table(ClientId Int,[Month] Int,[Year] Int,ColumnValue1 Int,ColumnValue2 Int, ColumnValue3 Int)
Insert Into @t Values(1,1,2012,20,30,50),(1,2,3012,25,35,40),(2,1,2012,28,38,48)

;With Cte As
(
    Select ClientId,[Month],ColumnName,ColumnNameValues
    From @t 
    UnPivot(ColumnNameValues For ColumnName In (ColumnValue1,ColumnValue2,ColumnValue3)) As unpvt
