Class InterfaceActionOnGenericClauseSetOrder

java.lang.Object
oracle.odi.interfaces.interactive.support.actions.InterfaceActionOnGenericClauseAbstract
oracle.odi.interfaces.interactive.support.actions.InterfaceActionOnGenericClauseSetOrder

All Implemented Interfaces:

IInterfaceAction

public class InterfaceActionOnGenericClauseSetOrder

extends InterfaceActionOnGenericClauseAbstract

InterfaceActionOnGenericClauseSetOrder is an interface action class used to set the processing order for a generic clause. The order is important for a join when the source technology supports ordered join, because it can help determine the overall order and functionality of the ANSI outer join clause.

For example, suppose there are 2 joins in the interface, Join1 is "A LEFT OUTER JOIN B", and Join2 is "B LEFT OUTER JOIN C". If Join1 has an order value of 10 and Join2 has an order value of 20, then the generated result will be "A LEFT OUTER JOIN B LEFT OUTER JOIN C". But if Join2 has an order value of 20 and Join1 has an order value of 10, then the generated result will be "B LEFT OUTER JOIN C RIGHT OUTER JOIN A". So it will affect the data result. A generic clause can be a Filter, TargetMapping, Join.

11.1.1.3.0
