hii Arun,

aura:iteration iterates over a collection of items and renders the body of the tag for each item. Data changes in the collection are rerendered automatically on the page. It also supports iterations containing components that are created exclusively on the client-side or components that have server-side dependencies.

Hi Shubham,

enqueueAction(action) adds the server-side controller action to the queue of actions to be executed. All actions that are enqueued will run at the end of the event loop.

Hii Udit,

Renderer service in the lightning component bundle modifies the DOM elements which are created by the framework for a component. We use the custom renderer to change or override the default rendering behavior of the component.

Hii Manish,

init is a predefined event sent to every component. After the component is initialized, the doInit action is called in the component's controller. In this sample, and thecontroller action sets an attribute value, but it could do something more interesting, such as firing an event.

BLOB data type. A BLOB (binary large object) is a varying-length binary string that can be up to 2,147,483,647 characters long. Like other binary types, BLOB strings are not associated with a code page. In addition, BLOB strings do not hold character data.Blob is a collection of Binary data which is stored as Object. This data types converts the attachments into a single object.

Hii Deepak,

$A.enqueueAction(action) sends the request the server. More precisely, it adds the call to the queue of asynchronous server calls. That queue is an optimization feature of Lightning.

Hii Ayush,

Hii Pooja,

apex:inputText: An HTML input element of type text. Use this component to get user input for a controller method that does not correspond to a field on a Salesforce object.

 

apex:inputField: An HTML input element for a value that corresponds to a field on a Salesforce object. The <apex:inputField> component respects the attributes of the associated field, including whether the field is required or unique, and the user interface widget to display to get input from the user. For example, if the specified <apex:inputField> component is a date field, a calendar input widget is displayed. When used in an <apex:pageBlockSection>, <apex:inputField> tags automatically display with their corresponding output label.

Hii Shweta,

Dynamic dashboards are used to display information tailored to a specific user, while a normal dashboard shows data only from a single user's perspective. Use dynamic dashboards when you want to show each user user-specific data, such as their personal quotas and sales, or number of case closures, or leads converted, etc. Use a normal dashboard when you want to show regional or organization-wide data to a set of users, such as a region's sales, or a support team's performance on case closures.

Hello Ratnesh,

SOSL statements evaluate to a list of lists of sObjects, where each list contains the search results for a particular sObject type. The result lists are always returned in the same order as they were specified in the SOSL query. If a SOSL query does not return any records for a specified sObject type, the search results include an empty list for that sObject.

Hello Ratnesh,

(Insert)()------

If we use the DML statement (insert), then in bulk operation if error occurs, the execution will stop. In that case Apex code throws an error and none of the record is inserted to the database.

Database.Insert()-----

If DML database methods (Database.insert) used, then if error occurs the remaining records will be inserted / updated means partial DML operation will be done. The only record throwing an error will not be inserted / updated.

Hi Ayush,

No, Synchronous Web service callouts are not supported from scheduled Apex. To be able to make callouts, make an asynchronous callout by placing the callout in a method annotated with @future(callout=true) and call this method from scheduled Apex. However, if your scheduled Apex executes a batch job, callouts are supported from the batch class.

Hii Ratnesh,

An Apex transaction represents a set of operations that are executed as a single unit. All DML operations in a transaction either complete successfully, or if an error occurs in one operation, the entire transaction is rolled back and no data is committed to the database. The boundary of a transaction can be a trigger, a class method, an anonymous block of code, a Visualforce page, or a custom Web service method.
