Below is the latest Syntax available to retrieve a record in Dynamics 365 Online V9.X using JavaScript,
Syntax:
Xrm.WebApi.retrieveRecord(entityLogicalName, id, options).then(successCallback, errorCallback);
Parameters:
| Name | Type | Required | Description |
| entityLogicalName | String | Yes | The entity logical name of the record you want to retrieve. For example: “account”. |
| id | String | Yes | GUID of the entity record you want to retrieve. |
| options | String | No | OData system query options, $select and $expand, to retrieve your data.
· Use the $select system query option to limit the properties returned by including a comma-separated list of property names. This is an important performance best practice. If properties aren’t specified using $select, all properties will be returned. · Use the $expand system query option to control what data from related entities is returned. If you just include the name of the navigation property, you’ll receive all the properties for related records. You can limit the properties returned for related records using the $select system query option in parentheses after the navigation property name. Use this for both single-valued and collection-valued navigation properties. You specify the query options starting with ?. You can also specify multiple query options by using & to separate the query options. For example: ?$select=name&$expand=primarycontactid($select=contactid,fullname) See examples later in this topic to see how you can define the options parameter for various retrieve scenarios. |
| successCallback | Function | No | A function to call when a record is retrieved. A JSON object with the retrieved properties and values will be passed to the function. |
| errorCallback | Function | No | A function to call when the operation fails. |
Return Value:
On success, returns a promise containing a JSON object with the retrieved attributes and their values.
Example:
Create a new Javascript Webresource (new_Account.js) and copy paste the below code in it and call it on OnLoad of the Account Form.
After that, open an Existing Account Record.
function RetrieveAccountRecord() {
var accountRecordGuid = null, nextLine = "\n";
accountRecordGuid = Xrm.Page.data.entity.getId();
if (accountRecordGuid != null && accountRecordGuid != "") {
// Retrieve Record
Xrm.WebApi.retrieveRecord("account", accountRecordGuid, "?$select=name,creditonhold,description,revenue,industrycode,_primarycontactid_value").then(
function success(result) {
// Perform operations on record retrieval
var sampleValueText = "Retrieved values: ";
// Single Line of Text
if (result.name != null) {
sampleValueText += "Account Name : " + result.name + nextLine;
}
// Two Option Set
if (result.creditonhold != null) {
sampleValueText += "CreditOnHold : " + result.creditonhold + nextLine;
}
// Multiple Lines of Text
if (result.description != null) {
sampleValueText += "Description : " + result.description + nextLine;
}
// Currency Field
if (result.revenue != null) {
sampleValueText += "Revenue : " + result.revenue + nextLine;
sampleValueText += "Revenue (Formatted Text) : " + result['revenue@OData.Community.Display.V1.FormattedValue'] + nextLine;
}
// Option Set
if (result.industrycode != null) {
sampleValueText += "Industry Text : " + result['industrycode@OData.Community.Display.V1.FormattedValue'] + nextLine;
sampleValueText += "Industry Value : " + result.industrycode + nextLine;
}
// Lookup
if (result._primarycontactid_value != null) {
sampleValueText += "Primary Contact GUID: " + result._primarycontactid_value + nextLine;
sampleValueText += "Primary Contact Logical Name: " + result['_primarycontactid_value@Microsoft.Dynamics.CRM.lookuplogicalname'] + nextLine;
sampleValueText += "Primary Contact Text: " + result['_primarycontactid_value@OData.Community.Display.V1.FormattedValue'] + nextLine;
}
Xrm.Utility.alertDialog(sampleValueText, null);
},
function (error) {
// handle error conditions
Xrm.Utility.alertDialog("Error while retrieving the Account Record : " + error.message, null);
}
);
}
}
Output:
Hope you have successfully retrieved Account record using New Syntax.
