JDBCJoin

java.lang.Object

public class JDBCJoin extends Object implements Serializable

Represents a join between two tables. The join is constructed with two <TABLE>.<COLUMN> strings. For example, if a BOOK table is joined to a AUTHOR table, this object might be constructed as:

JDBCJoin join = new JDBCJoin("BOOK.AUTHOR", "AUTHOR.AUTHOR_ID");

The result is a join that looks like:

BOOK.AUTHOR = AUTHOR.AUTHOR_ID
