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?

  • @AdrianLarson - what if a field does use it? for example a Global Value Set which is used with Custom Settings which does not support picklist

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

SObjectField picklistUsingGlobal = SObjectType.MyObject__c.fields.PicklistUsingGlobal__c.getSObjectField();
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.

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.

  • In Setup, open a Picklist Value Set. There's a Fields Where Used table in the page. Obviously this approach is somewhat fragile, since there's no indication on the field itself that this dependency is being assembled, but you could create a dummy field just for the purpose and mention the controller in its description.
