    Unanswered: inner join and outer joins

    I have seen code where the inner join is explicitly used, i also have seen code where the usage is just join.

    select * from a
    inner join b on


    select * from a
    join b on

    Can anyone explain what are the differences between these two joins?
    Thank you.

    the keyword INNER is optional

    however, it is always a good idea to write it anyway

    same with LEFT JOIN -- the keyword OUTER is optional but i always write it | @rudydotca
