これを行うには、動的SQLを使用する必要があります。大まかなコードは次のようになります。

ALTER PROCEDURE [dbo].[_sp_GetDMActivityTrackerReport]

    @Month INT,
    @FiscalYear INT

    @colsNull AS NVARCHAR(MAX),
    @colsSum AS NVARCHAR(MAX),

execute(@query)

一時テーブルを使用する代わりに、@FiscalMonthこのために永続的なテーブルを作成することをお勧めします。動的SQLを使用する場合、一時テーブルよりもパーマテーブルに対してクエリを実行する方がはるかに簡単です。一時テーブルは、動的クエリの範囲外である可能性があります。

Oracle には、ハードコーディングを回避できる PIVOT XML オプションがあります。SQL Server にそのようなオプションがあるかどうかはわかりません。これをsmth lk書くことができます-また、Oracleクエリ：

SELECT count(decode(state,'FL',custid)) "FL"
     , count(decode(state,'NY',custid)) "NY"
     , count(decode(state,'CA',custid)) "CA"
FROM scott.customer
GROUP BY state
/

状態を月などに置き換えます... 出力:

FL  NY  CA
--- --- ---
0   2   0
5   0   8

オラクルの例:

http://www.oracle-base.com/articles/11g/pivot-and-unpivot-operators-11gr1.php

SELECT * FROM   
(
 SELECT product_code, quantity
   FROM   pivot_test
)
PIVOT XML
(
 SUM(quantity) AS sum_quantity 
  FOR (product_code) IN (SELECT DISTINCT product_code 
                        FROM   pivot_test
                       WHERE  id < 10)
)
