私はSQLクエリを持っています:

  SELECT
  TAT,
  SUM(CASE WHEN [Month Entered] = 1 THEN 1 ELSE 0 END) JAN,
   SUM(CASE WHEN [Month Entered] = 2 THEN 1 ELSE 0 END) FEB,
   SUM(CASE WHEN [Month Entered] = 3 THEN 1 ELSE 0 END) MAR,
   SUM(CASE WHEN [Month Entered] = 4 THEN 1 ELSE 0 END) APR,
   SUM(CASE WHEN [Month Entered] = 5 THEN 1 ELSE 0 END) MAY,
   SUM(CASE WHEN [Month Entered] = 6 THEN 1 ELSE 0 END) JUN,
   SUM(CASE WHEN [Month Entered] = 7 THEN 1 ELSE 0 END) JUL,
   SUM(CASE WHEN [Month Entered] = 8 THEN 1 ELSE 0 END) AUG,
   SUM(CASE WHEN [Month Entered] = 9 THEN 1 ELSE 0 END) SEP,
   SUM(CASE WHEN [Month Entered] = 10 THEN 1 ELSE 0 END) OCT,
   SUM(CASE WHEN [Month Entered] = 11 THEN 1 ELSE 0 END) NOV,
   SUM(CASE WHEN [Month Entered] = 12 THEN 1 ELSE 0 END) [DEC]

  FROM
  [SalesDWH].[dbo].[TurnAround]
  where DATEPART(yyyy,[datetime entered])=2010
  GROUP BY TAT
  ORDER BY 1;

返されるものは次のとおりです。

+-----+-----+-----+-----+-----+-----+-----+-----+-----+-----+-----+-----+-----+

+-----+-----+-----+-----+-----+-----+-----+-----+-----+-----+-----+-----+-----+

出力を次のようにしたい：

0すべての が削除され、TAT列が 0,1,2,3,4,...... と連続していることに注意してください。

これら2つの条件を強制するにはどうすればよいですか?

0 から 191 までの TAT の値にこれが必要です。

値が 192 以上の場合、192 での TAT を 192 以上のすべての値の合計にしたい

まず、最初の列のすべての値を含むテーブルを作成し、データテーブルを結合する必要があります

次に、このクエリに加えて別のクエリを実行すると（つまり、これはサブクエリになります）、各月の列は次のようになります。

 case jan when 0 then '' else cast(jan as nvarchar) end jan
