inner join

(database)   (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.
