sql查询使用pivot动态添加会计月份

Question

ALTER PROCEDURE [dbo].[_sp_GetDMActivityTrackerReport]

@Month INT,
@FiscalYear INT
AS 
BEGIN    

INSERT @FiscalMonth (ID,Month,NbHolidays,MonthDate,TotalDays)

pivot 
(
sum(Days)
for Month in (April, May, June, July, August, September, October,November, December, January, February, March)
)
piv 

@Fiscalmonth returns:
Id, Month, NbHolidays, MonthDate
1   April     1 4/1/2012
2   May   2 5/1/2012 
3   June      3 6/1/2012
4   July      4 7/1/2012
5   August    5 8/1/2012
6   September 6 9/1/2012
7   October   7 10/1/2012
8   November  8 11/1/2012
9   December  9 12/1/2012
10  January   10    1/1/2013
11  February  11    2/1/2013
12  March     12    3/1/2013

我有一个存储过程,根据会计年度生成报告.这里的财政年度和财政月来自数据库现在我面临着动态生成此报告的问题,因为你可以看到我已经修复了月份这不是一个好的做法我希望它在某种程度上如果我改变了财政月份数据库然后我的报告相应地反映.

您将需要使用动态SQL来执行此操作.该粗糙代码将是类似这样的:

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 +@FiscalMonth)
            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 +@FiscalMonth)
            FOR XML PATH(''), TYPE).value('.', 'NVARCHAR(MAX)') ,1,1,'')

select @colsSum = STUFF((SELECT distinct '+ IsNull(' + QUOTENAME(DateName(Month,nft.MonthPeriodStart))+', 0)'
                    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 +@FiscalMonth)
            FOR XML PATH(''), TYPE).value('.', 'NVARCHAR(MAX)') ,1,1,'')+' as [Total Field TIME] '

set @query = 'SELECT PreparationID,CoachId,UserID, MemberID,
                    [Rep Name], ' + @colsNull + ', '+ @colsSum+' 
             from 
             (
                SELECT up.PreparationID,
                    tt.UserId [CoachId],
                    up.UserID, utm.MemberID, 
                    (ui.FirstName + '' '' + ui.LastName) AS [Rep Name],
                    DateName(Month,nft.MonthPeriodStart) [Month], 
                    sum(nft.Quantity) [Days]
                FROM TransferedTime tt
                INNER JOIN UPreparation up 
                    ON tt.PreparationID = up.PreparationID 
                RIGHT JOIN UTeamMembers utm 
                    ON tt.UserId = utm.CoachID AND utm.MemberID = up.UserID
                INNER JOIN UserInfo ui 
                    ON utm.MemberID = ui.UserID
                LEFT JOIN NonFieldTime nft 
                    ON nft.UserId = tt.UserId 
                    AND tt.MonthPeriodFrom = nft.MonthPeriodStart
                    AND datename(Month,nft.MonthPeriodStart) + ''-''+ substring(datename(Year,nft.MonthPeriodStart),3,2) IN 
                        (SELECT Month +''-'' +substring(datename(Year,MonthDate),3,2) [Months] 
                         FROM +@FiscalMonth)
                WHERE utm.MemberID IN (SELECT MemberID 
                                        FROM UTeamMembers 
                                        WHERE CoachID = '+@CoachId+')
                GROUP BY up.PreparationID,tt.UserId,up.UserID, utm.MemberID,
                (ui.FirstName + '' '' + ui.LastName),DateName(Month,nft.MonthPeriodStart)
            ) x
            pivot 
            (
                sum(Days)
                for Month in (' + @cols + ')
            ) p '

execute(@query)

我的建议而不是使用临时表@FiscalMonth是为了创建一个永久的表.使用动态sql时,查询perm表而不是临时表会更简单.临时表可能超出动态查询的范围.
