First we need to understand what is SOQL query afterwards we can take few examples to explain. We use SOQL query to search salesforce data for specific information. It is similar to the 'select' statement which we can widely used in SQL, but this will specially for only salesforce. You can write and execute a SOQL query in Apex code or in the salesforce Developer Console’s Query Editor. Before we start writing and executing queries, we need some data in salesforce org that we need to search. We can add any details which we need to search or that information is already stored into our database.

With SOQL, you can construct simple but powerful query strings in the following environments: -In the query string parameter in the query() call -In apex statements -In visualforce controllers and getter methods -In the schema explorer of the force dot com IDE

Page Reference class in Salesforce?

The PageReference is one of the most commonly used classes in Visualforce programming. an instance of the PageReference class can be used to refer to another web page. This may be another Visualforce page, another standard page, or, it could be a web page outside your Salesforce. A Page Reference is a reference to an instantiation of a page. Among other attributes, Page References consist of a URL and a set of query parameter names and values.

Instance methods for Page Reference

getAnchor()

getContent()

getContentAsPDF()

getCookies()

getHeaders()

getParameters()

getRedirect()

getUrl()

setAnchor(String)

setCookies(Cookie[])

setRedirect(Boolean)

you can define action methods using the <apex:commandButton> and other tags. These action methods allow you to define certain tasks that should be carried out when the corresponding button or link is clicked on a visualforce page. You can define an action method as returning nothing (void), but that is equivalent to returning a NULL PageReference object.

There are multiple ways to instantiate a page reference in Apex. Below are list of all possible ways.

1st method

PageReference pageRef = new PageReference('***partialURL***');

PageReference pageRef = new PageReference('***FullURL***');

Eg:

PageReference pageRef = new PageReference('/apex/CustomPage1?id=xxxxxx');

PageReference pageRef = new PageReference('/a04');

PageReference pageRef = new PageReference('http://www.google.com');

2nd Method

PageReference pageRef = Page.<<VF Page Name>>;

Eg:

PageReference pageRef = Page.CustomPage;

Standard Controllers:

A Visualforce controller is an arrangement of directions that indicate what happens when a client cooperates with the parts determined in related Visualforce page markup, for example, when a client clicks a catch or connection. Controllers likewise give access to the information that thought to be shown in a page, and can alter segment conduct.

Custom controllers

It is an Apex class which can implement all the logic for a page without leveraging standard controller. We can use custom controllers when we want our Visualforce page to run entirely into a system mode.

Standard Controller:

Standard controller in apex, inherits all the standard object properties and standard button functionality directly.

It contain the same functionality and logic that are used for standard Salesforce pages.

It Can be used with standard objects and custom objects.

It can be extended to implement custom functionality using extensions keyword.

It provides a save method to allow you to persist changes.

You’d use this when you have a singe object to manipulate.

Custom Controller:

It is an Apex class that implements all of the logic for a page without leveraging a standard controller.

Custom Controllers are associated with Visualforce pages through the controller attribute.

Custom controller defines its own functionality.

Use custom controllers when you want your Visualforce page to run entirely in system mode, which does not enforce the permissions and field-level security of the current user.

You’d use this when your page isn’t dealing with a main object.

Create & Use Custom Controllers

Prologue to Custom Controllers:

Custom controllers contain custom rationale and information control that can be utilized by a Visualforce page. How Visualforce bolsters the Model– View– Controller (MVC) plan design for building web applications. Controllers regularly recover the information to be shown in a Visualforce page, and contain code that executes in light of page activities, for example, a catch being clicked. When you utilize the standard controller, a lot of, well, standard usefulness is given to you by the stage.

Make a Visualforce Page that Uses a Custom Controller:

By or take a reference the name of the controller class

<apex:page> controller Attribute

At the point when your page utilizes a custom controller, you can't utilize a standard controller.

• Open the Developer Console and snap File | New | Visualforce Page to make another Visualforce page. Enter Contacts List Controller for the page name.

• In the editorial manager, supplant any markup with the accompanying.

<apex:page controller="ContactsListController">

   <apex:form>

       <apex:pageBlock title="Contacts List" id="contacts_list">            

           <!-- Contacts List goes here -->

       </apex:pageBlock>

   </apex:form>

</apex:page>

When you try to save this page, you’ll get an error, because Contacts List Controller doesn’t exist yet.
