inner join
     
         (Commonly "join", but see also "{outer join}") A
        {relational database} operation which selects rows from two
        {tables} such that the value in one {column} of the first
        table also appears in a certain column of the second table.
     
        An example in {SQL}:
     
        	select * from A, B
        	where A.x = B.y
     
        The column names (x and y in this example) are often, but not
        necessarily, the same.
