SELECT DISTINCT ON expressions must match initial ORDER BY expressions

开发说pg中执行sql报错，发来消息让帮看看：

SELECT DISTINCT ON expressions must match initial ORDER BY expressions

　　

详细语句如下：

SELECT DISTINCT ON
	( p_no ) p_no,
	p_name,
	p_manager,
	p_manager_no,
	p_dept
FROM
P
WHERE
	corporation = $1
	AND status = $2
ORDER BY
	create_time DESC

　　

失败的原因看看官方文档就知道了：
