Dynamically generate URL from Database in ASP.NET MVC?

You're thinking of this a little backward. Generally, one wouldn't do this by generating it directly from the database. You would generally do this by routing the url batch /somepersonal/ to some personalpage control, which would then consider everything after it, like xyz_abc to be an argument. Personalpage would then use that argument to customize its display, be it from the database or wherever.

So to clarify, your URL would look something like:

http://something.com/personal/vish_soni
http://something.com/personal/colonel_gentleman
http://something.com/personal/general_specific

But all of these are being routed to Personalpage, which then uses vish_soni, colonel_gentleman, and general_specific as arguments to query the database or do whatever else it needs to do.

Microsoft has an overview of this pattern and routing in general here.

You can create a controller class and call an action method. For your case, you just need to send parameter and then lookup customer info to prepare the content.

 public class HomeController : Controller
{

    public ActionResult Me(string id)
    {
        ViewBag.Message = "Welcome to ASP.NET MVC! "+id;
        var contentobj = repository.GetUSerContent(id);
        return View("Index",contentobj);
    }
}
