SQL embedded in programs on the application server might use the SQL system date clause.
在应用服务器上程序嵌入的SQL可能使用SQL系统日期子句。
Finally, the return clause returns the new node representing the scheduled termination date so that DB2 will update data in the DOCUMENT column with the modified data.
最后,return子句返回代表预定终止日期的新节点,所以DB 2将用修改后的数据更新document列中的数据。
The order by posted desc clause forces the query to return rows in descending order by the date in the posted column (which is the date that the article was posted on the Web site).
order by posted desc子句强迫此查询按posted列中的日期(即文章发布到Web站点的日期)的降序返回行。
