I'm using Case object and it has a look up of Service_Technician__c. Now i want to get the Service technician name which is related to a Case. How can i retrieve a service technician name using SOQL? I tried like below:

sforce.connection.query("SELECT Id, CaseNumber, Reason, Status, (SELECT Id, Name FROM Service_Technician__c WHERE id= '"+account.Assigned_To__c+"'),Service_Date__c FROM Case WHERE Status='New'",{
    onSuccess : layoutResults,
    onFailure : queryFailed,
    source : {
        output : document.getElementById("output"),
        startTime : new Date().getTime()

Assigned_To__c is a look up name in Case Object

    You could just put a formula field on the case to pull in the tech name

What you are doing right now (i.e. using a sub-query) would work for querying child-relations. But in this case you're following a lookup and not querying a child-relation at all.

In the case of querying a lookup field, you can simply use the __r version of the fieldname to query fields from that relation. So in this case use Assigned_To__r.Name to query the Name of the Technician.

SELECT Id, Assigned_To__r.Name FROM Case WHERE Status='New'

See the documentation for more information.

  • I am getting the following error.. SELECT Service_Technician__r.Name FROM ^ ERROR at Row:1:Column:8 Didn't understand relationship 'Service_Technician__r' in field path. If you are attempting to use a custom relationship, be sure to append the '__r' after the custom relationship name. Please reference your WSDL or the describe call for the appropriate names.

  • Then Service_Technician__c is not a lookup field. You said it is, right? May 19, 2017 at 13:40
  • Assigned_To__c is a field in Case object, it is a look up of Service_Technician__c May 22, 2017 at 6:02
  • Got it. It should be Assigned_To__r.Name May 22, 2017 at 6:36
  • Ah ok, so the lookup field is Assigned_To__c and it references the Service_Technician__c object. I've updated my answer to reflect that! If it worked, please accept this answer or if it didn't: write your own and accept that one :-) May 22, 2017 at 8:15
