Is it possible to retrieve the values of a Global Picklist/GlobalValueSet using Schema class without a SOQL ?

    Can't you just use describes on a field that implements it? – Adrian Larson Nov 2 '16 at 23:48

My strategy here would simply be to describe a picklist field that implements the Global Picklist.

SObjectField picklistUsingGlobal = SObjectType.MyObject__c.fields.PicklistUsingGlobal__c;
List<PicklistEntry> entries = picklistUsingGlobal.getDescribe().getPicklistValues();

    I get Compile failure on line 1, column 14: Illegal assignment from Schema.DescribeFieldResult to Schema.SObjectField using this snippet on Contact.Custom_Field_With_Value_Set__c. Using Hari's snippet all works fine. – Swisher Sweet Mar 1 '19 at 19:48

Schema.DescribeFieldResult F = <Object_API_Name>.<Field_API_Name>.getDescribe();
Schema.sObjectField T = F.getSObjectField();
List<PicklistEntry> entries = T.getDescribe().getPicklistValues();

    But how can you tell if a field is employing a global value set? Where can you access that dependency information? For example, I want to loop around all the fields in my object and preform a task only if that field uses a particular global value set. Use of that GVS groups these fields together by purpose. To pick a field that is 'known' to be using a GVS requires information that should not be necessary. – Flippsie Sep 12 '19 at 16:03
