What are the types of custom settings in Salesforce?

Hi Manpreet,

Custom settings are similar to custom objects and enable application developers to create custom sets of data, as well as create and associate custom data for an organization, profile, or specific user.

Custom Setting enables efficient access without the cost of repeated queries to the database. This data can then be used by formula fields, validation rules, Apex, and the Web services API. Custom Setting are of 2 types Hierarchy Custom Settings and List Custom Setting.

Hi Manpreet,

Custom settings are similar to custom objects, where we can create custom object where can create custom field, store our data. Custom Settings are essentially custom objects that are exposed in the applications cache and are accessible via their own API.

Custom settings are of two types:

1.      List custom settings

2.      Hierarchy custom settings

List Custom Settings

Here can store our data and display that data without using soql.If we are using soql to fetch or display same record for multiple times it might  hit governing limit ,to avoid that we can use list custom setting.

I have object named student__c where I need to fetch record on frequently basis. I am displaying record using soql.

List<student__c>stu= [select name, phone__c ,email__c, mark__c  from student__c];

Salesforce runs Multi-tenant environment, so there is chances of hitting governor limit in salesforce,

If I store that in custom object I can fetch withoutusing soql.we can fetch data using custom setting methods,

Here customsetting object name is student__c

Public class Studentexample{

Public List<student__c>stuList{set;get;}

Public Studentexample(){

stuList= new list<student __c>();

Map<string,student__c>Mapstu=stu.getAll();

stuList=mapstu.values();

}

}

We can display that record in visualforce page

<apex:pageblocktable value={“!stuList”} var=”s”>

<apex:colum value=”{!s.name}”/>

<apex:colum value=”{!s.phone__c}”/>

<apex:colum value=”{!s.Mark__c}”/>

<apex:colum value=”{!s.Email__c}”/>

</apex:pageblocktable>

Hierarchy Custom Settings

This type of   custom setting that help to customize settings for specific profiles or users. The hierarchy logic checks the organization, profile, and users. We can override profile or user organization per wide. We canby-pass validation to a particular profile or user.

Object name is  Hierarchy Settingsexample__c

Hierarchy Settingsexample__c Hcs=HierarchySettingsexample __c.getInstance();

We can choose user by this method userInfo.getUserId();

We can choose profile by this method userinfo.getprofileid();

HI

Custom settings are similar to custom objects and enable application developers to create custom sets of data, as well as create and associate custom data for an organization, profile, or specific user. All custom settings data is exposed in the application cache, which enables efficient access without the cost of repeated queries to the database. This data can then be used by formula fields, validation rules, Apex, and the SOAP API.

There are two Types of Custom settings
List Custom Settings : A type of custom setting that provides a reusable set of static data that can be accessed across your organization. If you use a particular set of data frequently within your application, putting that data in a list custom setting streamlines access to it.

Hierarchy Custom Settings : Hierarchy settings allow you to personalize your application for different profiles and/or users. A type of custom setting that uses a built-in hierarchical logic that lets you “personalize” settings for specific profiles or users. The hierarchy logic checks the organization, profile, and user settings for the current user and returns the most specific, or “lowest,” value. In the hierarchy, settings for an organization are overridden by profile settings, which, in turn, are overridden by user settings.

Thanks
