Performing Insert Update Delete Operation on Entity Using OData in Dynamics CRM 2011

This post describes the way to update the entity for all different type of fields in the entity

As shown in the sample below it creates a new account with different set of types

 var account = {};
account.Name = "Test Account Name";
account.Description = "This account was created by the JQueryRESTDataOperations sample.";
if (primaryContact != null) {

  //Set a lookup value
  account.PrimaryContactId = { Id: primaryContact.ContactId, LogicalName: "contact", Name: primaryContact.FullName };

}

 //Set a picklist value
  account.PreferredContactMethodCode = { Value: 2 }; //E-mail

//Set a money value
  account.Revenue = { Value: "2000000.00" }; //Set Annual Revenue

//Set a Boolean value
  account.DoNotPhone = true; //Do Not Allow

 var jsonEntity = window.JSON.stringify(account);

    var serverUrl = Xrm.Page.context.getServerUrl();
    var ODATA_ENDPOINT = "/XRMServices/2011/OrganizationData.svc/AccountSet";
    var ODataPath = serverUrl + ODATA_ENDPOINT;
    $.ajax({
        type: "POST",
        contentType: "application/json; charset=utf-8",
        datatype: "json",
        url: ODataPath + "(guid'" + accountId + "')",
        data: jsonEntity,
        beforeSend: function (XMLHttpRequest) {
            XMLHttpRequest.setRequestHeader("Accept", "application/json");
            XMLHttpRequest.setRequestHeader("X-HTTP-Method", "MERGE");
        },
        error: function (xmlHttpRequest, textStatus, errorThrown) {
            alert("Status: " + textStatus + "; ErrorThrown: " + errorThrown);
        }
    });


If you observe the about code the following statement defines whether the ODATA call is for update or insert

For Update
            XMLHttpRequest.setRequestHeader("X-HTTP-Method", "MERGE");

For Delete
            XMLHttpRequest.setRequestHeader("X-HTTP-Method", "DELETE");
          
For Insert
           XMLHttpRequest.setRequestHeader("Accept", "application/json");
