Executes an SQL statement, returning a result set as a PDOStatement object
( string statement )
PDO::query() 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 query that you need to issue multiple times, you will realize better
performance if you prepare a PDOStatement object using
PDO::prepare() and issue the statement with multiple
calls to PDOStatement::execute().
If you do not fetch all of the data in a result set before issuing your
next call to PDO::query(), your call may fail. Call
PDOStatement::closeCursor() to release the database
resources associated with the PDOStatement object before issuing your
next call to PDO::query().
