weblogic.jdbc.rowset.JoinRowSetImpl
public class JoinRowSetImpl
JoinRowSetImpl is an implementation of the JDBC JoinRowSet API (javax.sql.JoinRowSet). The JoinRowSet interface describes a mechanism by which a meaningful relationship can be drawn between any standard RowSet implementations. Any number of disconnected RowSet objects can be added to an instance of JoinRowSet provided the RowSet objects can be related in a SQL JOIN By definition, the SQL JOIN statement is used to combine the data contained in two relational database tables based upon a common attribute. By establishing and then enforcing column matches, a JoinRowSet object establishes relationships between RowSet instances without the need for database access. This permits greater flexibility, particularly for disconnected applications.
