ピボットを使用して会計月を動的に追加するSQLクエリ

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

ALTER PROCEDURE [dbo].[_sp_GetDMActivityTrackerReport]
    @CoachId VARCHAR(7),
    @Month INT,
    @FiscalYear INT
AS 
BEGIN    

INSERT @FiscalMonth (ID,Month,NbHolidays,MonthDate,TotalDays)
EXECUTE dbo._sp_GetFiscalMonths @Month, @FiscalYear

DECLARE @cols AS NVARCHAR(MAX),
    @colsNull AS NVARCHAR(MAX),
    @colsSum AS NVARCHAR(MAX),
    @query  AS NVARCHAR(MAX)

select @cols = STUFF((SELECT distinct ',' + QUOTENAME(DateName(Month,nft.MonthPeriodStart)) 
                    from NonFieldTime nft
                    where datename(Month,nft.MonthPeriodStart) + '-'+ substring(datename(Year,nft.MonthPeriodStart),3,2) 
                        IN (SELECT Month +'-' +substring(datename(Year,MonthDate),3,2) [Months] 
                            FROM [email protected])
            FOR XML PATH(''), TYPE).value('.', 'NVARCHAR(MAX)'),1,1,'')

select @colsNull = STUFF((SELECT distinct ', IsNull(' + QUOTENAME(DateName(Month,nft.MonthPeriodStart))+', 0) as '+DateName(Month,nft.MonthPeriodStart)
                    from NonFieldTime nft
                    where datename(Month,nft.MonthPeriodStart) + '-'+ substring(datename(Year,nft.MonthPeriodStart),3,2) 
                        IN (SELECT Month +'-' +substring(datename(Year,MonthDate),3,2) [Months] 
                            FROM [email protected])
            FOR XML PATH(''), TYPE).value('.', 'NVARCHAR(MAX)') ,1,1,'')

set @query = 'SELECT PreparationID,CoachId,UserID, MemberID,
                    [Rep Name], ' + @colsNull + ', '+ @colsSum+' 
             from 
             (

            pivot 
            (
                sum(Days)

execute(@query)
  

 一時テーブル @FiscalMonth を使用する代わりに私の提案 このために永続的なテーブルを作成することです。動的 SQL を使用する場合は、一時テーブルではなく永続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。一時テーブルが動的クエリの範囲外である可能性があります。
