> A semi-join between two tables returns rows from the first table where one or
> more matches are found in the second table. The difference between a
> semi-join and a conventional join is that rows in the first table will be
> returned at most once. Even if the second table contains two matches for a
> row in the first table, only one copy of the row will be returned. Semi-joins
> are written using the EXISTS or IN constructs.
> An anti-join is the opposite of a semi-join and is written using the NOT
> EXISTS or NOT IN constructs.
> There's a pretty good write-up [here]
> (http://www.dbspecialists.com/files/presentations/semijoins.html) on
> semi/anti joins.
