ASP.NET C# periodically updating website value from SQL

Hi

I have a website which is displaying data from an SQL database. The data in the database is updated about once every second. At the moment I am using a timer on the website to execute a stored procedure which gets the new value from the database, and then updates the value on the site using an UpdatePanel. The timer "ticks" every 0,8 seconds.

I want the value on the website to be as close to "real-time" as possible, and I was wondering if this is the most effective way of doing this?

Is it possible of "push" the value from the SQL database directly to the website when a new value is inserted into the table using a database trigger?

As far as I know, you can't do that. Note that the value you're showing into your website is taken from SQL Server, so when you show the value it's the right, exact value stored in the database in that moment.

Why do you want to do "fine tuning" in this? Is the way you're using to get the value time-expensive? Is there a heavy delay from the moment in which the value is stored in SQL to the moment in which is shown in your website?

Hi Luis

Using the timer works as it should. I was just wondering if there was a way to do this with having to run a stored procedure ever 0,8 second.

I know you can trigger events in the SQL database using triggers, and I was just wondering if it was possible to update a website value from SQL.
