Question

我有一个类似的查询：

-- --JOIN one
LEFT MERGE JOIN 
(SELECT TT.TAXAMOUNT,TT.TAXCODE,TT.TAXITEMGROUP,TT.VOUCHER,TT.TAXORIGIN, TTF.SOURCERECID
FROM TAXTRANS TT
INNER MERGE JOIN TAXTABLE TAX ON TAX.PAYMENTTAXCODE = TT.TAXCODE AND TAX.DATAAREAID = 'vb'
INNER MERGE JOIN TAXTRANS TTF ON TAX.TAXCODE = TTF.TAXCODE AND TTF.SOURCEDOCUMENTLINE = TT.SOURCEDOCUMENTLINE
WHERE TT.TRANSDATE between @FECHA_INI AND @FECHA   
AND TT.TAXORIGIN = 11 AND ("+@Codigo_IEPSCUOTAP_TT+")) TTIEPSCUOTA ON 
C1.TT_VOUCHER = TTIEPSCUOTA.VOUCHER 
AND C1.TT_TAXITEMGROUP = TTIEPSCUOTA.TAXITEMGROUP
AND PRO.TTF_SOURCERECID = TTIEPSCUOTA.SOURCERECID 


 --JOIN two
LEFT MERGE JOIN 
(SELECT TT.TAXAMOUNT,TT.TAXCODE,TT.TAXITEMGROUP,TT.VOUCHER,TT.TAXORIGIN, TTF.SOURCERECID
FROM TAXTRANS TT
INNER MERGE JOIN TAXTABLE TAX ON TAX.PAYMENTTAXCODE = TT.TAXCODE AND TAX.DATAAREAID = 'vb'
INNER MERGE JOIN TAXTRANS TTF ON TAX.TAXCODE = TTF.TAXCODE AND TTF.SOURCEDOCUMENTLINE = TT.SOURCEDOCUMENTLINE
WHERE TT.TRANSDATE between @FECHA_INI AND @FECHA
AND TT.TAXORIGIN = 11 AND ("+@Codigo_IEPS25P_TT+")) TTIEPS25 ON 
C1.TT_VOUCHER = TTIEPS25.VOUCHER 
AND C1.TT_TAXITEMGROUP = TTIEPS25.TAXITEMGROUP 
AND PRO.TTF_SOURCERECID = TTIEPS25.SOURCERECID

正如您所看到的，Join one和Join two是相同的连接，除了最后4行，所以我决定创建一个临时表来调用select一次，如：

IF OBJECT_ID('tempdb..##TTC' ) IS NOT NULL DROP TABLE ##TTC 
GO


SELECT * INTO ##TTC FROM (
SELECT
TT.TAXAMOUNT,
TT.TAXCODE,
TT.TAXITEMGROUP,
TT.VOUCHER,
TT.TAXORIGIN,
TT.SOURCERECID,
FROM TAXTRANS TT 
INNER MERGE JOIN TAXTABLE TAX ON TAX.PAYMENTTAXCODE = TT.TAXCODE AND TAX.DATAAREAID = 'vb'
INNER MERGE JOIN TAXTRANS TTF ON TAX.TAXCODE = TTF.TAXCODE AND TTF.SOURCEDOCUMENTLINE = TT.SOURCEDOCUMENTLINE
WHERE TT.TRANSDATE between @FECHA_INI AND @FECHA   
AND TT.TAXORIGIN = 11
GO

现在我已经全部选择进入我的表，现在我想知道如何用最后4行查询实现我的时态表，有人可以帮忙吗？此致

你可以试试这个。

;WITH TTC AS
(SELECT TT.TAXAMOUNT,TT.TAXCODE,TT.TAXITEMGROUP,TT.VOUCHER,TT.TAXORIGIN, TTF.SOURCERECID
FROM TAXTRANS TT
INNER MERGE JOIN TAXTABLE TAX ON TAX.PAYMENTTAXCODE = TT.TAXCODE AND TAX.DATAAREAID = 'vb'
INNER MERGE JOIN TAXTRANS TTF ON TAX.TAXCODE = TTF.TAXCODE AND TTF.SOURCEDOCUMENTLINE = TT.SOURCEDOCUMENTLINE
WHERE TT.TRANSDATE between @FECHA_INI AND @FECHA   
AND TT.TAXORIGIN = 11 AND ("+@Codigo_IEPSCUOTAP_TT+"))

-- MAIN TABLE
-- --JOIN one
LEFT MERGE JOIN 
TTC TTIEPSCUOTA ON 
C1.TT_VOUCHER = TTIEPSCUOTA.VOUCHER 
AND C1.TT_TAXITEMGROUP = TTIEPSCUOTA.TAXITEMGROUP
AND PRO.TTF_SOURCERECID = TTIEPSCUOTA.SOURCERECID 


 --JOIN two
LEFT MERGE JOIN 
TTC TTIEPS25 ON 
C1.TT_VOUCHER = TTIEPS25.VOUCHER 
AND C1.TT_TAXITEMGROUP = TTIEPS25.TAXITEMGROUP 
AND PRO.TTF_SOURCERECID = TTIEPS25.SOURCERECID

使用时态表重构连接
