How are you executing the query (ExecuteNonQuery, ExecuteScalar, etc.) ?  Are you expecting a return value or a result set?

Are you sure it's inserting any rows?  You insert clause

"where l.email_address='" + (alternateLogin) + "' and '" + (username) + "' = null"

Would not return any rows since it would be comparing '{username}' = null, which would always be false.
