Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).


TIMESTAMPTZ_CMP_TIMESTAMP compares the value of a timestamp with time zone expression with a timestamp expression. If the timestamp with time zone and timestamp values are identical, the function returns 0. If the timestamp with time zone is greater chronologically, the function returns 1. If the timestamp is greater, the function returns –1.

Return type



The following example compares timestamps with time zones to timestamps and shows the results of the comparison.

SELECT TIMESTAMPTZ_CMP_TIMESTAMP('2008-01-24 06:43:29+00', '2008-01-24 06:43:29'), TIMESTAMPTZ_CMP_TIMESTAMP('2008-01-24 06:43:29+00', '2008-02-18 02:36:48'), TIMESTAMPTZ_CMP_TIMESTAMP('2008-02-18 02:36:48+00', '2008-01-24 06:43:29'); timestamptz_cmp_timestamp | timestamptz_cmp_timestamp | timestamptz_cmp_timestamp ---------------------------+---------------------------+--------------------------- 0 | -1 | 1
