public class SqlOrderBy
extends SqlCall

Parse tree node that represents an ORDER BY on a query other than a SELECT (e.g. VALUES or UNION).

It is a purely syntactic operator, and is eliminated by SqlValidatorImpl.performUnconditionalRewrites(org.apache.calcite.sql.SqlNode, boolean) and replaced with the ORDER_OPERAND of SqlSelect.
