PDO::query() prepares and executes an SQL statement in
a single function call, returning the result set (if any) returned by the
statement as a PDOStatement object.
For a SELECT statement that you need to issue multiple times, prepare
a PDOStatement object with PDO::prepare() and issue
the statement with PDOStatement::execute().
