What is the difference between list custom setting and hierarchy custom setting?

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

Hi Surbhi,

There are separate methods for Hierarchy custom settings and list custom settings.

For example, I have used one method getorgdefaults() in code. So basically what happens in this case is, the code fetches the field details from that custom setting and gets used. In my case, it was a batch class.

So you can follow this URL to get somewhat idea regarding this:

https://developer.salesforce.com/docs/atlas.en-us.apexcode.meta/apexcode/apex_methods_system_custom_settings.htm

And when you go to custom settings you can see what type is it(hierarchy/list)...

Hi,

Hierarchical Custom Settings

Use this for your most of your VF/Apex config settings for stand alone apps
Don’t put in settings which are environment dependent (e.g. if you have separate test server URLs that should be used in Sandbox vs. Production)
Definitely, if you are storing User Preferences, Hierarchical is the way to go.
List Custom Settings

Use this if you creating config for a common piece of code that appears in different areas of Salesforce
Use this when there are environmental differences such as Test server URLs vs. Production server URLs
Also can be used as a simple table for frequently used data

Hope this helps.
