Thank you for that statement.

so what have you done yet and what do you mean by frequently?

Have you ever heard about Google?

yep but i can't find relevant info.

i just need to display an information when a new row was inserted by user A to alert User B without clicking a button to refresh so that he/she can see what new data was inserted, those users are from different place and use the same database on a server.

Listen to Original Griff... "frequent" queries from all clients is very bad scaling and not a performant solution - Forget about it.

Why on earth would you want to do that?
Use an SqlDependancy[^] and let the DB tell you!

This should help: http://blogs.microsoft.co.il/blogs/oshvartz/archive/2008/06/07/query-notification-dependency-sqldependency-class.aspx[^]
