In Trailhead we have the query to get the Contacts for the Account named "SFDC Computing", with an inner query.

 SELECT Name, (SELECT LastName FROM Contacts) FROM Account WHERE Name = 'SFDC Computing'

It works fine for my purposes. "Contacts" is the name of the relationship, per Trailhead. So, I went to Object Manager and examined the Account object's "Fields and Relationships". There is nothing named "Contacts"!

In general, how do I get the name of the relationship, for use in similar SOQL queries?

  • I've linked four other questions that demonstrate a number of ways to find the relationship, including Apex Code, workbench, etc, as well.

You look at the relationship lookup field on the child object. Here's an example from Contact, whose lookup field to Account is AccountId:

For custom relationship fields, the relationship name must be postfixed with __r in SOQL, and queries against objects in a different namespace must be prefixed with the relevant namespace, i.e., MyNs__My_Relationship__r.
