There are times where I find Select TOP Order By [ASC/DESC] does not make sense but BOTTOM. Does SQL Server support the bottom command?

    Hi,@Jonathan Brotto

    Does SQL Server support the bottom command?

    No, SQL Server doesn’t support BOTTOM.
    We always need order by clause when using TOP or BOTTOM(if it is supported).
    If without ORDER BY ,results of SELECT BOTTOM N would be exactly the same as results of SELECT TOP N - undefined.
    The result of SELECT BOTTOM N ... ORDER BY ... ASC is exactly the same as result of SELECT TOP N ... ORDER BY ... DESC.
    So, there is no need to have two key words that do the same thing.

    Actually, TOP is used to limit results to specific number of rows.
    As for another similar function keyword 'OFFSET', it is ANSI standard and it adds pagination.
    Please refer to this document for more details of OFFSET and ORDER BY.

    What I'm curious about is what situation makes you think Select TOP Order By [ASC/DESC] does not make sense
    If you want to retrieve TOP and BOTTOM Rows Together,please refer to this link .

    No, there is no BOTTOM operator.

    Rather than TOP you can do as in this example:

    SELECT *
    FROM   sys.objects
    ORDER BY name
    SELECT TOP 5 *
    FROM  sys.objects
    ORDER BY name

    These two queries return the same result.

    Hi Jon,

    If you want the last 100 rows but still in ascending order, you can use another select statement around the first:


    select * from (select top 100 * from table order by date desc) a order by;  


    select * from (select * from table order by date desc limit 100) a order by;  

    Think of it this way: You are sorting the rows first and then selecting how many from the top of that sorted list.
    That should help it make sense to you.

    The MySQL command is maybe a bit more intuitive in that regard.
