Question

我在下面有一个示例查询，它使用GETDATE来提取最新的估算值。该表有两个日期列，effectiveDate和toDate。问题？我想提取每周价值，以便我可以得到一系列时间估计值。如果我现在运行查询，我将最终得到截至今天的所有估算，但我也想知道他们上周，前一周的情况等等。

我应该创建一个包含我想要的日期的新表，然后根据查询结果加入它们。这是我被困的地方。谢谢。

select GETDATE() as observeDate
, (select C.companyName from ciqCompany C where C.companyId = EP.companyId) as companyName
, (select EPT.periodTypeName from ciqEstimatePeriodType EPT where EPT.periodTypeId = EP.periodTypeId) as periodTypeName
, EP.fiscalYear
, EB.brokerName as brokerName
, EA.firstName+' '+EA.lastName as AnalystName
, EDND.tradingitemid
, (select DI.dataItemName from ciqdataitem DI where DI.dataitemid = EDND.dataitemid) as dataItemName
, (select EAS.accountingStandardDescription from dbo.ciqEstimateAccountingStd EAS where EAS.accountingStandardId = EDND.accountingStandardId) as AccountingStandard
, (select Cu.ISOCode from ciqCurrency Cu where Cu.currencyid = EDND.currencyid) as ISOCode
, (select EST.estimateScaleName from ciqEstimateScaleType EST where EST.estimateScaleId = EDND.estimateScaleId) as estimateScaleName
,EDND.dataItemValue,EDND.effectiveDate,EDND.isExcluded
from ciqEstimatePeriod EP
--- link estimate period table to detailed numeric data table
----------------------------------------------------------
join ciqEstimateDetailNumericData EDND
on EDND.estimatePeriodId = EP.estimatePeriodId
and GETDATE() between EDND.effectiveDate and EDND.toDate
----------------------------------------------------------
left outer join ciqEstimateBroker EB
on EB.estimateBrokerId = EDND.estimateBrokerId --- left outer join must be used if you receive any of the anonymous estimates packages
left outer join ciqEstimateAnalyst EA
on EA.estimateAnalystId = EDND.estimateAnalystId --- left outer join must be used if you receive any of the anonymous estimates packages
where EP.companyId = 112350 -- IBM
and EP.periodTypeId = 1 -- annual
and EDND.dataItemId = 21634 --- EPS Normalized (Detailed)
and EP.fiscalYear = 2010
order by 4,5,6,10

Answer 1

这个查询足够复杂 - 我不想添加它。我可能会根据需要将其转换为视图或存储过程并从中查询。然后你也可以将日期范围作为输入而不仅仅是GETDATE（）。

SQL - 在日期范围内加入具有观察结果的日期列表
