将存储的数据用于查询 SSIS

Question

我有一个获取数据的查询，因此我将其存储到 OLEDB Connection 中，因为我想将该数据多次用于另一个查询

查询

SELECT * FROM (
SELECT
TT.VOUCHER,
TT.TAXITEMGROUP,
TT.TAXCODE,
TT.SOURCEBASEAMOUNTCUR,
TT.SOURCETAXAMOUNTCUR,
TTGJAERIVA.TAXTRANSRELATIONSHIP,
TTGJAERIVA.GENERALJOURNALACCOUNTENTRY,
TTGJAERIVA.LEDGERDIMENSION,
GJAERIVA.TEXT,
GJAERIVA.LEDGERDIMENSION AS LEDGERDIMENSIONGAE,
GJAERIVA.POSTINGTYPE
FROM TAXTRANS TT 
INNER MERGE JOIN TAXTRANSGENERALJOURNALACCOUNTENTRY TTGJAERIVA ON TTGJAERIVA.TAXTRANS = TT.RECID
INNER MERGE JOIN GENERALJOURNALACCOUNTENTRY GJAERIVA ON TTGJAERIVA.GENERALJOURNALACCOUNTENTRY = GJAERIVA.RECID 
AND GJAERIVA.POSTINGTYPE IN( 14,236,71,41) 
AND TT.TRANSDATE <= '2015-04-30'
WHERE   
(TT.TAXORIGIN <> 11 AND TT.TRANSDATE BETWEEN  '2015-01-01' AND  '2015-04-30') OR (TT.TAXORIGIN = 11 AND TT.TRANSDATE BETWEEN '2015-01-01' AND  '2015-04-30' )) AS T

然后我创建另一个 OLEDB 连接，在那里我有另一个查询，我使用来自第一个查询的数据

第二次查询（仅相关代码）

LEFT MERGE JOIN 
(SELECT TTRIVA.*,TTGJAERIVA.GENERALJOURNALACCOUNTENTRY FROM TAXTRANS TTRIVA 
INNER MERGE JOIN TAXTRANSGENERALJOURNALACCOUNTENTRY TTGJAERIVA ON TTGJAERIVA.TAXTRANS = TTRIVA.RECID
INNER MERGE JOIN GENERALJOURNALACCOUNTENTRY GJAERIVA ON TTGJAERIVA.GENERALJOURNALACCOUNTENTRY = GJAERIVA.RECID 
AND GJAERIVA.POSTINGTYPE IN( 14,236,71) AND TTRIVA.TRANSDATE <=@FECHA) TTRIVA ON TT.VOUCHER = TTRIVA.VOUCHER 
AND TT.SOURCERECID = TTRIVA.SOURCERECID 
AND TT.TAXITEMGROUP = TTRIVA.TAXITEMGROUP 
AND (TTRIVA.TAXCODE LIKE 'RIVA%')
AND TTRIVA.GENERALJOURNALACCOUNTENTRY = TTGJAE.GENERALJOURNALACCOUNTENTRY


--JOIN PARA RETENCIONES DE ISR PAGADAS
LEFT MERGE JOIN 
(SELECT TTRISR.*,TTGJAERIVA.GENERALJOURNALACCOUNTENTRY FROM TAXTRANS TTRISR
INNER MERGE JOIN TAXTRANSGENERALJOURNALACCOUNTENTRY TTGJAERIVA ON TTGJAERIVA.TAXTRANS = TTRISR.RECID
INNER MERGE JOIN GENERALJOURNALACCOUNTENTRY GJAERIVA ON TTGJAERIVA.GENERALJOURNALACCOUNTENTRY = GJAERIVA.RECID 
AND GJAERIVA.POSTINGTYPE IN( 14,236,71) AND TTRISR.TRANSDATE <=@FECHA) TTRISR ON TT.VOUCHER = TTRISR.VOUCHER AND TT.SOURCERECID = TTRISR.SOURCERECID 
AND TT.TAXITEMGROUP = TTRISR.TAXITEMGROUP 
AND (TTRISR.TAXCODE LIKE 'RISR%')
AND TTRISR.GENERALJOURNALACCOUNTENTRY = TTGJAE.GENERALJOURNALACCOUNTENTRY

--JOIN PARA IEPSCUOTA
LEFT MERGE JOIN 
(SELECT TTIEPSCUOTA.*,TTGJAERIVA.GENERALJOURNALACCOUNTENTRY FROM TAXTRANS TTIEPSCUOTA
INNER MERGE JOIN TAXTRANSGENERALJOURNALACCOUNTENTRY TTGJAERIVA ON TTGJAERIVA.TAXTRANS = TTIEPSCUOTA.RECID
INNER MERGE JOIN GENERALJOURNALACCOUNTENTRY GJAERIVA ON TTGJAERIVA.GENERALJOURNALACCOUNTENTRY = GJAERIVA.RECID 
AND GJAERIVA.POSTINGTYPE IN( 14,236,71) AND TTIEPSCUOTA.TRANSDATE <=@FECHA) TTIEPSCUOTA ON TT.VOUCHER = TTIEPSCUOTA.VOUCHER AND TT.SOURCERECID = TTIEPSCUOTA.SOURCERECID 
AND TT.TAXITEMGROUP = TTIEPSCUOTA.TAXITEMGROUP 
AND (TTIEPSCUOTA.TAXCODE LIKE 'IEPSCUOTAP') 
AND TTIEPSCUOTA.GENERALJOURNALACCOUNTENTRY = TTGJAE.GENERALJOURNALACCOUNTENTRY

如您所见，我在每个LEFT JOIN 中都使用了FROM TAXTRANS，但我将TAXTRANS 存储在第一个查询中。如何用第一个查询数据替换第二个查询？

数据流：

Answer 1

如果可以在单个集合中完成查询并合并查询，有什么需要？如果您仍然希望在单独的批处理基础上进行查询，我建议首先将您想要重复使用的查询插入到临时表（#表）中。使用该临时表左连接您的其他查询。将其全部封装在存储过程中，然后获取数据。要进一步提高性能，请检查是否可以合并索引。

带有排序的合并连接是一种非常昂贵的转换，它会影响性能。此外，您正在寻求的是 T-SQL 改进，而 SSIS 转换不能替代它
