How to select single row based on the max value in multiple rows [duplicate]

Answer 1

You can use a not exists subquery to filter out older records:

select  *
from    YourTable yt
where   not exists
        (
        select  *
        from    YourTable older
        where   yt.name = older.name and 
                (
                    yt.major < older.major or
                    yt.major = older.major and yt.minor < older.minor or
                    yt.major = older.major and yt.minor = older.minor and
                        yt.revision < older.revision
                )
        )

which can also be written in MySQL as:

select  *
from    YourTable yt
where   not exists
        (
        select  *
        from    YourTable older
        where   yt.name = older.name and 
                  (yt.major,    yt.minor,    yt.revision) 
                < (older.major, older.major, older.revision)
        )
