在SQL Server中安排作业

Question

I have a Leave_info table in that there are 4 columns:

empid, Cl, SL, LOP

The default value at the beginning of every year for CL,SL,LOP is

12, 6, 0.

This update has to be done automatically by the server on every year Jan 1st 12am. How to do this?

Answer 1

If your server has SQL Server Agent installed, you can create a job and schedule it to run at 12:00am on the 1st of each year.

Here's a quick how-to on creating a job : http://technet.microsoft.com/en-us/library/ms190268.aspx

If you do not have SQL Server Agent installed then you can write an application, compile it, and then set a Windows Scheduled Task on the server to run your application based on your needed yearly schedule.

( Or cron job in Linux environment if not MS SQL Server )
