org.apache.derby.impl.sql.compile.SelectNode
A SelectNode represents the result set for any of the basic DML operations: SELECT, INSERT, UPDATE, and DELETE. (A RowResultSetNode will be used for an INSERT with a VALUES clause.) For INSERT - SELECT, any of the fields in a SelectNode can be used (the SelectNode represents the SELECT statement in the INSERT - SELECT). For UPDATE and DELETE, there will be one table in the fromList, and the groupByList fields will be null. For both INSERT and UPDATE, the resultColumns in the selectList will contain the names of the columns being inserted into or updated. @author Jeff Lichtman
