    Yes, you can join more than 2 tables. Take this for example:

    select

    *

    from table1 a

    inner join table2 b

    on a.id = b.t1_id

    inner join table3 c

    on a.id = c.t1_id;

    Not a problem, and you are correct. I do recommend getting a beginner's book on SQL Server, as there are a lot of introductory topics that are required to be learned in order to advance your knowledge.

    RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
    First step towards the paradigm shift of writing Set Based code:
    ________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

    Change is inevitable... Change for the better is not.
