Table Programming Model

Example Table Definition [Data. Service. Key("Partition. Key", "Row. Key")] public class Customer { // Partition key – Customer Last name public string Partition. Key { get; set; } // Row Key – Customer First name public string Row. Key { get; set; } // User defined properties here public Date. Time Customer. Since { get; set; } public double Rating { get; set; } } public string Occupation { get; set; }

Create and Insert Entity Customer cust = new Customer( “Lee”, // Partition Key = Last Name “Geddy”, // Row Key = First Name Date. Time. Utc. Now, // Customer Since 2. 0, // Rating “Engineer” // Occupation); // Service Uri is “http: //<Account>. table. core. windows. net/” Data. Service. Context context = new Data. Service. Context(service. Uri); context. Add. Object(“Customer”, cust); Data. Service. Response response = context. Save. Changes();

Query a Table Data. Service. Context context = new Data. Service. Context(“http: //myaccount. table. core. windows. net”); var customers = from o in context. Create. Query<Customer>(“Customer”) where o. Partition. Key == “Lee” select o; foreach (Customer customer in customers) { } GET http: //myaccount. table. core. windows. net/Customer? $filter= Partition. Key eq ‘Lee’
