Question

Since i’m not strong in asp.net, probably my question will sound silly. I’ve got remote sql server db and it has to be updated every month automatically. How can i solve this problem?

Answer 1

You need to break your question down into its constituent parts, which seem to be:

1. I need to delete some data
2. I need to perform a task (deleting data) at a certain time every month

Deleting data

You need to have something that can be used to delete data that fits a given set of criteria. Precisely how it does this will depend on how your application (I’m assuming you’ve got a server somewhere which hosts a website/application and a Sql Server database that contains the data for it). This could be:

• A web page / service
• An executable program
• A batch file

How you delete the data will be dependent on what tool (such as Entity Framework, NHibernate or plain SQL you’ve used to implement your data access, but will ultimately come down to something like:

DELETE
FROM    MyNewsTable
WHERE   NewsItemDate < '2012-01-01 00:00:00.000'
// '2012-01-01 00:00:00.000' will be whatever date you want 
// to delete news items for

Performing a task at a certain time

As you’re using Sql Server you (may) have two choices (three if you count triggering it manually), these are:

• A Sql Server task
• A Windows Scheduled Task

Either of these can be used to trigger a program that you’ve written or, with the help of a 3rd party tool, call a web service / page.
