SELECT DISTINCT ON expressions must match initial ORDER BY expressions

開發說pg中執行sql報錯，發來消息讓幫看看：

SELECT DISTINCT ON expressions must match initial ORDER BY expressions

　　

詳細語句如下：

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

　　

失敗的原因看看官方文檔就知道了：
