I have a grouped table that looks like this: |End_of_Month_Date|VersionId| |-----------------|---------| |2024-06-30 |1 | |2024-06-30 |2 | |2024-07-31 |1 | |2024-07-31 |2 | |2024-07-31 |3 | |2024-07-31 |5 | For each month end, I want to pull in the Max(VersionId) so that in the end I have a unique End_of_Month_Date and max(VersionId). |End_of_Month_Date|VersionId| |-----------------|---------| |2024-06-30 |2 | |2024-07-31 |5 | I've tried writing the code, but it's not working correctly:
select distinct c.END_OF_MONTH_DATE, c.VERSION_ID, 'Assets'
    from dbo.Contracts_Version_Details c
    	inner join(
    		select distinct max(c1.Version_Id) as MaxVersionId, c1.END_OF_MONTH_DATE
    		from dbo.Contracts_Version_Details c1
    		group by c1.End_of_month_date) mv
    		on c.VERSION_ID = mv.MaxVersionId
    	inner join(
    				select distinct max(c2.END_OF_MONTH_DATE) as MaxDate, c2.VERSION_ID
    				from dbo.Contracts_Version_Details c2
    				group by c2.VERSION_ID
    			) as md
    			on c.END_OF_MONTH_DATE = md.MaxDate
