You can nest select queries like this

SELECT A.Column, B.Column
FROM
    (SELECT Column FROM table1 ...) A
    INNER JOIN
    (SELECT Column FROM table2 ...) B
    ON A.id = B.id

This combines the rows of one data source (table or sub query) with the rows of the other one. If you query from several data sources, you will usually have to join them in some way. If you do not, you will get a Cartesian product, which combines each row of one source with each row of the other source.
