public final Class OrderSiblingsByClause

extends AbstractOrderByClause
Class Inheritance
In a hierarchical query, if the rows of siblings of the same parent need to be ordered, then the ORDER SIBLINGS BY clause should be used. Either ORDER BY or GROUP BY should not be used, as they will destroy the hierarchical order of the CONNECT BY results.
BNF: order_sibling_by_clause ::= ORDER SIBLINGS BY orderby_item {, orderby_item}*
