PreparedStatements are precompiled. When you create a
PreparedStatement you supply a SQL statement. This statement
is passed right along to your database where it is compiled
and cached. The advantage of this is that if you are running
a query multiple times the database will not have to compile
it each time before it is run. This can result in a hefty
performance boost.
