Hi,

I am writing a program that parses through rss feeds in craigslist and displays the date, title, link and description and writes it to sql database.

I have 2 taks that I need help with.

1. Prevent the program from entering duplicate data. For example, somoene might repost their ad more than once within a few minutes.

2. Set up a timer that automatically uploads the data every, say 10 minutes.

Thank you,

推荐答案

您坚持做什么?防止输入重复数据非常简单.一个计时器?您可以从外部引导该应用开始运行x分钟，如果它不需要持续/始终运行，这不是一个坏选择.

What are you stuck on? Preventing duplicate data from being entered is quite simple. A timer? You can steer the app from the outside to kick off ever x minutes, it''s not a bad option if it need not be persistent/always running.
