Tutorial :Is it possible to access a profile without updating LastActivityDate?



Question:

In asp.net (using MVC, but this happens in regular too)

Profile.GetProfile(username);  

will update the LastActivityDate for that user. This is not intended when someone else is viewing that user's profile.

In the membership class you can specify whether to update this date with a second param, like so:

Membership.GetUser(username, false); // doesn't update LastActivityDate  Membership.GetUser(username, true); // updates LastActivityDate  

Is there anyway to do something similar in the Profile provider without writing my own provider?


Solution:1

You might use one ugly workaround which includes changing aspnet_Profile_GetProperties stored procedure. This one is responsible for getting the properties while accessing user profile.

Open this procedure and you will find following code at the bottom:

IF (@@ROWCOUNT > 0)  BEGIN      UPDATE dbo.aspnet_Users      SET    LastActivityDate=@CurrentTimeUtc      WHERE  UserId = @UserId  END  

Remove it in order to stop updating the LastActivityDate. You will still get LastActivityDate updated when calling Membership.GetUser(username, true);.


Solution:2

You might look at using a provider that someone else has written, rather than write your own.

This one on Scott Guthrie's blog includes stored procedures which could be called directly by your own code to get the information:

This page has an msi download which installs a sample application for working with custom Profile data. The table based profile performs a lot better than the default on, where all of the profile data is contained in a single database field. The table based one is also a lot easier to query directly, which will help you with your question. The stored procedure from the sample schema is called getCustomProfileData

Otherwise, just query the database directly.
