I'm doing a project called personal manager using ASP.NET 4.5 using C# and SQL Server 2012. As an example I store the details of driving license including it's expiry date.
What I want to do is to check this expiry date and present date and find whether it matches. If it matches I want to send a mail to the person informing the same.
I read about triggers and stored procedure but don't know how to implement this.
