Question

我正在尝试将代码的第一部分放在一起声明。

DECLARE @FYEND date, @YTD date, @PYTD date, @Openmonth date, @Monthtodatefrom date, @Monthtodateto date, @Priormonthdatefrom date, @Priormonthdateto date, @Currentmonth date

SET @FYEND = Dateadd(year,1,DATEADD(year,DATEDIFF(month,'19010701', getdate() ) /12,'19010701'))
SET @YTD = GETDATE()
SET @PYTD = DATEADD(YEAR,-1,@YTD)
SET @Openmonth = dateadd(DAY,1,dateadd(YEAR,-1,EOMONTH(@YTD,-1)))
SET @Monthtodatefrom = EOMONTH(getdate(),-2)
SET @Monthtodateto = Dateadd(DAY,1,eomonth(@ytd,-1))
SET @Priormonthdatefrom= DATEADD(YEAR,-1,@monthtodatefrom)
SET @Priormonthdateto= dateadd(year,-1,Dateadd(DAY,1,eomonth(@ytd,-1)))
SET @Currentmonth=dateadd(DAY,1,EOMONTH(getdate(),-1))


SELECT
b.T3,

FROM

SELECT 
s.T3,
s.DIVISION_NAME as Division_Name,

WHERE gl.Period > CASE WHEN MONTH(@Monthtodatefrom) <= 6 THEN
                    CONCAT(YEAR(@Monthtodatefrom), RIGHT(CONCAT('000', MONTH(@Monthtodatefrom) + 6), 3))
                    ELSE CONCAT(YEAR(@Monthtodatefrom) + 1, RIGHT(CONCAT('000', MONTH(@Monthtodatefrom) - 6), 3))
                    END and gl.Period < CASE WHEN MONTH(@Monthtodateto) <= 6 THEN
                    CONCAT(YEAR(@Monthtodateto), RIGHT(CONCAT('000', MONTH(@Monthtodateto) + 6), 3))
                    ELSE CONCAT(YEAR(@Monthtodateto) + 1, RIGHT(CONCAT('000', MONTH(@Monthtodateto) - 6), 3))
                    END


GROUP BY
a.T3,
a.Country_name,
a.Division_Name,
a.SHOP_NAME,
a.Shop_Type
)b

但是当我想加入第二条语句时它不返回值，如果没有加入，我要求第二条语句为 0。

代码的第二部分在这里，我在查询 b 下设置

Inner join Finance_PRD.ANZ.ConsolidatedAUD as gl
on b.T3 = gl.T3

Inner JOIN Finance_PRD.dbo.ChartOfAccounts coa
on gl.AccountCode = coa.Code

WHERE gl.Period > CASE WHEN MONTH(@Priormonthdatefrom) <= 6 THEN
                    CONCAT(YEAR(@Priormonthdatefrom), RIGHT(CONCAT('000', MONTH(@Priormonthdatefrom) + 6), 3))
                    ELSE CONCAT(YEAR(@Priormonthdatefrom) + 1, RIGHT(CONCAT('000', MONTH(@Priormonthdatefrom) - 6), 3))
                    END and gl.Period < CASE WHEN MONTH(@Priormonthdateto) <= 6 THEN
                    CONCAT(YEAR(@Priormonthdateto), RIGHT(CONCAT('000', MONTH(@Priormonthdateto) + 6), 3))
                    ELSE CONCAT(YEAR(@Priormonthdateto) + 1, RIGHT(CONCAT('000', MONTH(@Priormonthdateto) - 6), 3))
                    END

我尝试了解所有不同的连接，甚至尝试使用 is null、if 和 coalesce 均无济于事。
