14. Database Creation: Example

15. Queries: Examples // Create the database form data context, using a connection string DataContext db = new WineDataContext("isostore:/wineDB.sdf"); // Find all wines currently at home, ordered by date acquired var q = from w in db.Wines where w.Varietal.Name == “Shiraz” && w.IsAtHome == true orderby w.DateAcquired select w;

17. Inserts/Updates/Deletes Wine newWine = new Wine { WineID = “1768", Name = “Windows Phone Syrah", Description = “Bold and spicy" }; db.Wines.InsertOnSubmit(newWine); db.SubmitChanges(); Wine wine = (from w in db.Wines where w.WineID == “1768" select w).First(); wine.Description = “Hints of plum and melon"; db.SubmitChanges(); Insert Update

18. Inserts/Updates/Deletes Delete var vineyardsToDelete = from Vineyards v in db.Vineyards where v.Country == “Australia” select v; db.Vineyards.DeleteAllOnSubmit (vineyardsToDelete); db.SubmitChanges(); Foreign key constraint will cause exception here if Wines associated with the Vineyards are not deleted first

19. Inserts/Updates/Deletes var vineyardsToDelete = from Vineyards v in db.Vineyards where v.Country == “Australia" select v; foreach (Vineyards v in vineyardsToDelete) { db.Wines.DeleteAllOnSubmit(v.Wines); } db.Vineyards.DeleteAllOnSubmit(vineyardsToDelete); db.SubmitChanges();

21. Database Schema Upgrades WineDataContext wineDC = new WineDataContext(App.WineDBConnectionString); DatabaseSchemaUpdater dsu = wineDC.CreateDatabaseSchemaUpdater(); if (dsu.DatabaseSchemaVersion == 1) { dsu.AddColumn ("BottleType"); dsu.DatabaseSchemaVersion = 2; dsu.Execute(); }

31. Contacts: Hello, World! Contacts contacts = new Contacts(); contacts.SearchCompleted += new EventHandler ((sender, e) => {... = e.Results; }); // E.g. search for all contacts contacts.SearchAsync(string.Empty, FilterKind.None, null); filter expression (not a regex) Filter kind: name, email, phone or pinned to start) state // E.g. search for all contacts with display name matching "ja" contacts.SearchAsync("ja", FilterKind.DisplayName, null);

32. Appointments: Hello, World! Appointments appointments = new Appointments(); appointments.SearchCompleted += new EventHandler ((sender, e) => {... = e.Results; }); // E.g. get next appointment (up to 1 week away) appointments.SearchAsync(DateTime.Now, DateTime.Now + TimeSpan.FromDays(7), 1, null); start date and time Maximum items to return state end date and time
