Question

I been trying to get sqlcachedependecy working, but it doesn’t appear to work

I got the proper settings in my web.config and also global.asa, however when I run this query and the changes are made to the database from either with in or outside the web site the cached objects are not updated please someone help? I know its not because this query is querying a view, because I tested this using straight SqlDependecy and the notification works fine.

  public IQueryable<VictoryList> GetVictoryList()    {                 string cacheKey = HttpContext.Current.User.Identity.Name + 'victoryCacheKey';                 IQueryable<VictoryList> cachednews = (IQueryable<VictoryList>)HttpContext.Current.Cache.Get(cacheKey);                  if (cachednews == null)                 {                      var results = from v in _datacontext.ViewVictoryLists                                   orderby _datacontext.GetNewId()                                   select new VictoryList                                   {                                       MemberID = v.MemberID,                                       Username = v.Aspnetusername,                                       Location = v.Location,                                       DaimokuGoal = v.DaimokuGoal,                                       PreviewImageID = v.PreviewImageID,                                       TotalDaimoku = v.TotalDaimoku,                                       TotalDeterminations = v.TotalDeterminations,                                       DeterminationID = v.DeterminationID,                                       DeterminationName = v.DeterminationName                                   };                     results = results.ToList().AsQueryable();                     SqlCacheDependencyAdmin.EnableNotifications(_datacontext.Connection.ConnectionString);                     SqlCacheDependency dependency =                      new SqlCacheDependency(_datacontext.GetCommand(results) as SqlCommand);                        HttpContext.Current.Cache.Insert(cacheKey, results, dependency);                      return results;                 }                 return cachednews;    }

According to the stated Limitations for creating a query for notification, listed at msdn…

The statement must not reference a view.
