Generated Keys

Generated Keys

When you add an output group, the Developer tool relates the output group to another output group with a generated key. The Developer tool adds a bigint key to the parent group and to the child group. At run time, the Data Integration Service creates the key values for the generated keys.

Example

The SOAP hierarchy has the following nodes: 
Departments
   Dept_Key
   Dept_Num
   Dept_Name
 
   Employees
      Dept_FK
      Employee_Num
      Employee_Name
When you create an output group of ports for Departments, you map the Departments node to an empty field in the Ports area. The Developer tool creates the following output group: 
Departments
   Dept_Num
   Dept_Name
When you map the Employees node to an empty field in the Ports area, the Developer tool prompts you to relate the Employees group to the Departments group. You can relate the Employees group to more than one group. The Developer tool adds a key to the each group.
The Developer tool creates the following groups and generated keys: 
Departments
   Key_Departments
   Dept_Num
   Dept_Name
 
   Employees
      Key_Departments
      Employee_Num
      Employee_Name
You do not have to map nodes to the generated keys. The Data Integration Service creates the key values at run time.
The Developer tool can create generated keys to multiple levels in one output group. The Employees group might contain the following ports: 
Employees
   Key_Employees
   Key_Departments
   Key_Managers
   Employee_Num
   Employee_Name
Key_Departments and Key_Managers are the generated keys that point to parent groups. Key_ Employees is a generated key for the Employees group. Key_Employees appears when you relate a child group to the Employees group.
