}示例3: COUNT
<p>Note: the code below generates <a href="http://docs.hp.com/en/36216-90103/ch03s02.html">
correlated (dependent) subqueries</a>. These are frequently not the
fastest way to run queries against your SQL engine. If there is an
opportunity to rewrite your subquery using simple joins, do it - this
will improve the performance of your applications dramatically.</p>
<p>In general, it's a good idea to use EXPLAIN statements to determine
the query execution plan of the SQL statement that QQuery generates
to determine what the SQL engine will actually do to run your queries.
This is one of the best ways to improve the performance of your
database-driven application.</p>
