如何获得某个值的最大日期和阶段名称？

Question

I am working on a query to pull the max date that is greater than a given period of time and have it return the value that is in that date. I'm working from a salesforce table and want to pull the max date that an opportunity is in and return the stage name that it is in. The date has to be greater than 5-1-14. So do I have to break this up into multiple queries? Give me the max date then return the stage name that its in. Any help would be appreciated!! Thanks!

SELECT OpportunityID,     

  Max(case when CREATEDDATE < '2014-05-01' THEN STAGENAME END) as Q1_FY15_Stage 

FROM [BVSFWarehouse].[dbo].[sf_OPPORTUNITYHISTORY]

GROUP by OPPORTUNITYID

Answer 1

You can filter your SELECT statement with a WHERE clause to limit the dates. Try:

SELECT
     OpportunityID
    ,STAGENAME
    ,MAX(CREATEDATE)
FROM BVSWarehouse.dbo.sf_OPPORTUNITYHISTORY
WHERE
    CREATEDATE > '2015-05-01'
GROUP BY
     OpportunityID
    ,STAGENAME
