# Project Name - SALESFORCE 'TYPEOF' USAGE FOR MULTI-REFERENCE FIEL

# Recipe URL - https://app.lingk.io/a/10932/tf/18147

# Description - # This recipe shows how to use the 'typeOf' SOQL statement in Salesforce.  
                # TYPEOF is an optional clause that can be used in a SELECT statement of a SOQL query when you’re querying data that contains polymorphic relationships. 
                # A TYPEOF expression specifies a set of fields to select that depend on the runtime type of the polymorphic reference.
