Example: CASE_N Partitioning Expression Using the END Bound Function - Advanced SQL Engine - Teradata Database

This example creates a table whose primary index is partitioned using a CASE_N expression and END bound functions.

     CREATE TABLE orders (        o_orderkey      INTEGER NOT NULL,        o_custkey       INTEGER,        o_orderperiod   PERIOD(DATE) NOT NULL        o_orderpriority CHARACTER(21),        o_comment       VARCHAR(79))      PRIMARY INDEX (o_orderkey)      PARTITION BY CASE_N (END(o_orderperiod) <= DATE '2010-03-31',/*Q1*/                           END(o_orderperiod) <= DATE '2010-06-30',/*Q2*/                           END(o_orderperiod) <= DATE '2010-09-30',/*Q3*/                           END(o_orderperiod) <= DATE '2010-12-31' /*Q4*/                          );
