Sitecore Custom User Profile - where is it stored how can it be queried

I have created a custom User profile template and object in the core database in Sitecore (as per the Security API Cookbook).

I can select this programmatically (as per the Security API Cookbook) so that my extranet users have an extended profile, that covers all the usual suspects (Address, phone, email format etc.)

However, where is this data stored? And how do I access it if I want to query the database to return a subset of users based on this profile data.

A typical requirement for an extranet member system is to extract a list of users to contact either in an email or a phone type campaign. Can this be done with the Sitecore membership system?

UPDATE> I'm going to take a guess and say the profile data is stored in aspnet_Profile.PropertyValuesBinary .. which would make it nigh on impossible to query and not suited to my purpose. That is unfortunate. So to extend my question, if that is the case, is it possible to get Sitecore to store those values开发者_如何学JAVA in the text field so they are searchable?

The standard Microsoft implementation of the SqlProfileProvider (which is used in Sitecore by default) stores the user profile information in the aspnet_Profile table. All the properties are serialized into the PropertyNames / PropertyValuesString columns. The PropertyValuesBinary is used to store the binary data (images). You can find more details if you look at the code of System.Web.Profile.SqlProfileProvider, SetPropertyValues method.

Next, all the custom properties you define in the user profile, are serialized to the SerializedData property of the Profile class, and it is again serialized to the PropertyNames / PropertyValuesString columns like any other property.

Also, couple of properties are stored in aspnet_Membership table (for some reason) - Email and Comment.

So, if you are going to query the users by Email, you can use FindUsersByEmail method of MembershipProvider. Otherwise, if you plan to filter by another property value, I suppose, you'll have to get all users and filter the obtained collection.

Hope this helps.

I faced this exact problem last week, didn't come up with a permanent solution, but to solve my particular issue, I wrote a little helper page and added it as a Sitecore application to be accessed from the CMS interface. All it did was query all users, and determine if they had any of like 5-6 profile properties assigned.

var userList = Sitecore.Security.Accounts.UserManager.GetUsers();

That is the relevant line to grab the users, it returns Sitecore.Common.IFilterable

So if you need to do something where you're grabbing profile info from all users, you cn do something like this:

foreach (Sitecore.Security.Accounts.User user in userList)
{
    Sitecore.Security.UserProfile profile = user.Profile;
    string whatever = profile["Whatever"];
    //add whatever to a list or something
}

This worked out very well for my purposes, but I don't know how feasible it will be in your situation.
