@FiscalYear INT
AS 
BEGIN    

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

@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，可以根据会计年度生成报告. 这里的会计年度和会计月份来自数据库，现在我面临着动态生成此报告的问题，因为您可以看到我已经修正了月份年份，这不是一个好习惯，我希望它以某种方式在我更改了会计年度的情况下生效数据库，然后我的报告将相应地反映出来.

I have a stored procedure which generate report according to the fiscal year. here fiscal year and fiscal month comes from the database now I am facing problem in generating this report dynamically as you can see i had fixed the months year which is not a good practice i want it to some way that if i changed the fiscal month in the database then my report reflect accordingly.

推荐答案

您将需要使用动态SQL来执行此操作. rough 代码将与此类似:

You will need to use dynamic SQL to do this. The rough code is going to be similar to this:

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)

            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,

                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

                    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+')

                (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，而是为此创建一个永久表.使用动态sql时，对一个烫发表而不是临时表进行查询会容易得多.临时表可能超出了动态查询的范围.

My suggestion instead of using the temp table @FiscalMonth is to create a table that is permanent for this. It will be much simpler to query against a perm table rather than the temp table when using dynamic sql. The temp table might be out of scope for the dynamic query.
