There is a course object with a marketing location lookup field. Marketing location object has state and country fields.

     (select State__c,Country__c from Marketing_Location__c) from Course__c")

It’s not work…..

I’m new to salesforce, so any help, thanks.

Answer 1

When queryign parent you use direct notation, not a subquery sicne there can be only one parent

QueryResult qr = binding.query("select CourseName__c, 
     Marketing_Location__r.State__c,
     Marketing_Location__r.Country__c from Course__c")

also, custom object names always use __c suffix (two underscores)
