How to get Value of Collection of Collection?
Let Say I have
Class Carrier Extends %Persistent
Property Employee As Array of Class Employees
Class Employees Extends %SerialObject
Property Name As %String
Property Address As Array of Class AddressDetail
Class AddressDetail Extends %SerialObject
Property Street1 As %String
Property Street2 As %String
I can get value for Employee Name as Employee_Name.
But I want to Get Value of Address Street1 and Street2 of Class AddressDetail using SQL Query
How can I get that?
