Question

Ok This is my situation, I am trying to bind a ListView with data(my user’s username) calling from my SProc, so each user photo of the ListView has a link to a profile page with query-string of their username attached. I realised that I may be able to do a join with the dbo.aspnet_Users to get their username, but is this advisable?

I understand we should use the membership API but I can’t think of a way not to get data from the aspnetdb database. Is there a more appropriate way of doing this? Thanks.

Yes, there is no harm in querying aspnet_Users or any other Microsoft Membership database table under normal circumstances.

But if you are dealing with fairly large number of records, it will effect the query performance. The reason behind it is that, INDEXING applied on Microsoft Membership tables is not very ideal. Most of the tables have ApplicationId as clustered index, which no one uses even rarely.

UserId is indexed, and LoweredUserName field is indexed in aspnet_membership and aspnet_users tables. So use them in your where clauses to boost up performance for large databases.

I hope this answers your question, if yes then mark it as “answered”.
