这是早期的合并报表优化记录，内容不多，保留下来备查。
一.查找源报表是否存在
SELECT 1 WHERE EXISTS (SELECT * FROM T_CSL_CslReport WHERE FSourceRptID = '4583062d-010a-1000-e002-63bbc0a8ef02B712EA2C')
未优化前:

给T_CSL_CslReport的FsourceRptID增加索引后:
执行成本:0.00641
Reads:43
Duration:0
增加索引后提高了50倍
Create Index IX_Csl_Rpt_SrcRpt On T_CSL_CslReport(FSourceRptID);
二.项目取数
SELECT sum(T_CSL_ItemDataEntry003.F670) "ZJ17001"
FROM T_CSL_ItemDataEntry ItemDataBd
INNER JOIN T_CSL_ItemData ItemDataHd ON ItemDataBd.FItemDataID = ItemDataHd.FID
LEFT OUTER JOIN T_Csl_RptReceived Received ON Received.FReportID = ItemDataHd.FReportID
LEFT OUTER JOIN T_CSL_ItemDataEntry003 ON ItemDataBd.FID = T_CSL_ItemDataEntry003.FID
LEFT OUTER JOIN T_ORG_Tree orgbound ON Received.FOrgTreeID = orgbound.FID
LEFT OUTER JOIN T_ORG_BaseUnit company ON ItemDataHd.FCompanyID = company.FID
LEFT OUTER JOIN T_BD_Currency cur ON ItemDataHd.FCurrencyID = cur.FID
LEFT OUTER JOIN T_BD_Currency tgtcur ON ItemDataHd.FTargetCurrencyID = tgtcur.FID
WHERE ((1 = 1 AND (orgbound.FNumber = '005' OR (orgbound.FNumber IS NULL)))
AND (((((company.FNumber IN ('0300100800')
AND tgtcur.FNumber = 'BB01')
AND ItemDataHd.FPeriodType = 1)
AND ItemDataBd.FYear = 2006)
AND ItemDataBd.FPeriod = 94)
AND ((ItemDataHd.FDataSource IN (1, 7)
AND ItemDataBd.FDataElement = 4)
AND ItemDataBd.FValueType = 1)))

给T_Csl_ItemDataEntry的增加索引(FvalueType,Fyear,Fperiod,FDataElement)后:
成本:0.0650
Reads:494

效率提高一倍,提升空间不是太大
Create Index IX_Csl_ItmDE_1 On
T_CSL_ItemDataEntry(FValueType,FYear,FPeriod,FDataElement);
