Hi,

You can use Batchable class:

public class ContactBatchable implements Database.Batchable<sObject>, Database.Stateful {
Integer total = 0;

public Database.QueryLocator start(Database.BatchableContext BC){
return Database.getQueryLocator('select Id from Contact');
}

public void execute(
Database.BatchableContext BC,
List<sObject> scope){
total += scope.size();
}

public void finish(Database.BatchableContext BC){
System.debug('total: ' + total);
}
}

And then execute the following statement in developer console:

Database.executeBatch(new ContactBatchable(), 2000);

Thanks.

Hi Shubham,

As Ajit and Nitish replied we can add page layout components and all. But if you are using Mozilla firefox, then you have to tell Firefox to accept third party cookies, because most of the page comes from the salesforce.com domain, and the iframe containing the VF page comes from force.com. Failing to allow third party cookies messes with the redirection.

Thanks.!!

Hello,

Try this once.. This has mine problem:

var prvsURL = document.referrer;

var getLoc = getParameterByName('loc',prvsURL);

function getParameterByName(name, url) {

name = name.replace(/[\[\]]/g, "\\$&");

var regex = new RegExp("[?&]" + name + "(=([^&#]*)|&|#|$)"),

results = regex.exec(url);

if (!results) return null;

if (!results[2]) return '';

return decodeURIComponent(results[2].replace(/\+/g, " "));

}

Hope this helps.

Hello Himanshu,

The major difference is when you return null the constructors defined in the controller class don't execute.

While if you return whole page the page gets refreshed and constructors get executed only if you have made setRedirect flag set to true.Hence we have an option either to flushout the viewstate or not using this approach.Returning ApexPages.currentPage() will provide us ability to choose set redirect as true or false depending on the business need for the page.

If you are using reRender tags for ajax actions then we prefer null as to avoid whole refresh of page .

Thanks.!

Hi there,

In RecursiveTriggerHandler class, we need to have a static variable which is need to set to true by default.

public class RecursiveTriggerHandler{

public static Boolean isFirstTime = true;
}

Find the sample trigger here:

trigger AccountTrigger on Account(after update){

Set<String> setOfAccId = new Set<String>();

if(RecursiveTriggerHandler.isFirstTime){
RecursiveTriggerHandler.isFirstTime = false;

for(Account accObj : Trigger.New){
if(accObj .name != ‘Test Name’){
setOfAccId .add(accObj .accountId);
}
}

// Use setOfAccId  in your logic
}
}

Once this trigger fired the static variable value will set to false and trigger will not fire again.

Hope this helps!

Hi Avanish,

If the record contains a roll-up summary field or is part of a cross-object workflow, performs calculations and updates the roll-up summary field in the parent record. Parent record goes through save procedure. So, updating the child inputs to a roll-up summary field can cause a trigger on an object to fire.

Consider the following example with a Master detail between Child and Parent and the following:

• Number field on Child called Num Field
• Roll-up summary on Parent that sums Num Field

Write the following trigger on Parent__c:

trigger ParentTrigger on Parent__c (before update) {
for (Parent__c p : Trigger.New) {
p.addError('Not going to save');
}
}

Now go into the new or edit page for your Child object and fill in a value for Num Field and save the record and see what happens. You get:

Error: Invalid Data.

Review all error messages below to correct your data.

Not going to save

Next, blank out the Num Field and save and see what happens. No error is generated and the Childsaves.

So when the child record is saved and the field feeds into the roll-up summary the parent trigger is executed.

Thanks

Hi

Community Cloud is a Salesforce platform that gives companies the tools to create branded online communities. These communities can be created for connecting with customers, external partners and employees.

Customer communities can be used for support and feedback. For companies with B2B business, partner communities can be used for qualifying leads, tracking revenue and providing product information and training. And internal employee communities can be resources for HR and IT information, as well as a place for discussion and collaboration.

 

Thanks.

Hi,

I think the scope for a Static variable in Apex is the entire transaction. Any static variables will maintain their value across that one transaction.

Hi

Salesforce introduced Lightning Data Service in Winter 17 as a pilot program. Use Lightning Data Service to load, create, edit, or delete a record in your component without requiring Apex code. Lightning Data Service handles sharing rules and field-level security for you.

It’s built on highly efficient local storage that’s shared across all components that use it. Records loaded in Lightning Data Service are cached and shared across components. Components accessing the same record see significant performance improvements, because a record is loaded only once, no matter how many components are using it. Shared records also improve user interface consistency. When one component updates a record, the other components using it are notified, and in most cases, refresh automatically.

Advantages of Lightning Data Service

• No need to write any Apex class
• No need to write SOQL
• Field level security and record sharing is inbuilt
• CRUD operation supported
• Shared cache is used by all standard and custom components
• Auto notification to all components
• Supports offline in Salesforce 1

THanks.

Hi

Undefined means a variable has been declared but has not yet been assigned a value, such as:

var TestVar;
alert(TestVar); //shows undefined
alert(typeof TestVar); //shows undefined

null is an assignment value. It can be assigned to a variable as a representation of no value:

var TestVar = null;
alert(TestVar); //shows null
alert(typeof TestVar); //shows object

 

THanks

Hi Anjali,

 

Lightning Data Service component, significantly reducing the complexity of your apps and pages. This reduced complexity means that you don’t have to spend as much time on performance and quality testing.

If there are many components on record detail page, then for each component there was SOQL to fetch data which affects the performance of the entire page. But if we use LDS it’s performance will improve as time lag to fetch data from server side will be saved.

 

Hope this will help you!

Formula Field is a field that updated everytime you load the page, it's not writable and you can't fire a trigger or a workflow based on the change of a formula field, can't answer that since I don't know what are you trying to achieve.

Pros: can update a field to another field, can update more field types than available for formula fields.  In general more robust then formula fields.

cons: subject to validation rules so could error out.  Can't update a formula field

vs. a Formula Field?

Pros; automatically calculate a value based on different rules/criteria.

​cons: Read-only, formula is static Can't use on certain fields like Rich Text Fields

Hi

Extension Controller is an Apex class that extends the functionality of a standard or custom controller.
It helps us to leverage the built-in functionality of a standard controller but override one or more actions, such as edit, view, save, or delete.
We can create new actions.
If used with standard controller it respects user permissions. I.e. if used with standard controller, the logic from the controller extension does not execute in system mode. Instead, it executes in user mode, in which permissions, field-level security, and sharing rules of the current user apply

Example:

Extension controller name : StdConExtensionCon

 

Thanks.

Custom setting like as Custom object where you can store your data .

major difference  is :

1  – Do not need to Query to access Data We can directly access them using methods

2 –
List custom setting :  Every User can Access
hierarchy custom setting : restrict data by user by Using ( User Id) .

3 – No owner is assigned when a custom setting is created

 

 

Thanks

Application Lifecycle is the process of managing an app’s development, from design to final release, and establishing a framework for managing changes. The typical application lifecycle starts with the design of a new app or feature. The app is planned based on requirements analysis and specifications. Next, the app is implemented per the specifications and then tested. The new app is staged for final testing before it gets deployed to production. This cycle repeats for every new app or feature. It’s also used for app maintenance, such as when features are enhanced or bugs are fixed.

Hi

You can query records for long text type field but you can’t get these fields in WHERE clause because the fields to be used in where clause if their length is greater than 255 which give incorrect result.
