Class InterfaceActionAddCrossJoin

java.lang.Object
  oracle.odi.interfaces.interactive.support.actions.InterfaceActionAddCrossJoin

All Implemented Interfaces:

IInterfaceAction

public class InterfaceActionAddCrossJoin
extends java.lang.Object
implements IInterfaceAction

InterfaceActionAddCrossJoin is an interface action class used to create create a join between two sources in an ODI interface data set. A cross join has no join condition and thus creates a cartesian product between the join sources. The two SourceDataStore objects are explicitly specified in the constructor.

The join that is created is owned by the DataSet object that is associated with the first passsed-in SourceDataStore. All sources that are joined must belong to the same data set. To change the properties of the join, for example to set the relationship between two of the join sources to be an outer join, use the InterfaceActionOnJoinSetJoinProperties class.

If the auto-fix manager is set up for the InteractiveInterfaceHelperWithActions helper, it is possible that the execution location of the join may be automatically changed, even if it has been explicitly set in the constructor.

The same join object should be used to join any number columns between 2 sources, using the "AND" SQL keyword to combine the join condition predicates.

11.1.1.3.0
