SQL Server Select the most recent record only

Question

I have a table tat looks like this:

Table1

ID Date       TermDate Cancel
1  20140101   99999999 20140102
1  20140101   20130102 20140102

2  20140108         


        

Answer 1

You can use dense_rank function to assign a rank to each row within one ID based on your ordering and get the first one for each ID:

select id, [date], termdate, cancel from
    (select id, [date], termdate, cancel,
        dense_rank() over (partition by id order by [date] desc, cancel desc, termdate desc) rank
    from table1) X
where rank = 1
