Following are the definitions of the tables used in the examples.

Here is the table definition for the sequenced PTI table src_s, which includes a time zero specification of October 15, 2016, DATE '2016-10-15', and time bucket duration of 1 hour, HOURS(1).

CREATE TABLE src_s(
      TD_TIMEBUCKET BIGINT NOT NULL GENERATED SYSTEM TIMECOLUMN,
      TD_TIMECODE TIMESTAMP(1) NOT NULL GENERATED TIMECOLUMN,
      TD_SEQNO INT NOT NULL GENERATED TIMECOLUMN,
      c1 INTEGER,
      c2 INTEGER)
 PRIMARY TIME INDEX (TIMESTAMP(1), DATE '2016-10-15', HOURS(1), COLUMNS(C1), SEQUENCED(500));

Below is the table definition for the sequenced PTI table tgt_s, which includes a time zero specification of October 15, 2016, DATE '2016-10-15', and time bucket duration of 1 hour, HOURS(1).
