IS_TIMESTAMP_*ΒΆ
Verifies whether a VARIANT value contains the respective TIMESTAMP value:
IS_TIMESTAMP_LTZ (value with local time zone).
IS_TIMESTAMP_NTZ (value with no time zone).
IS_TIMESTAMP_TZ (value with time zone).
- See also:
SyntaxΒΆ
IS_TIMESTAMP_LTZ( <variant_expr> )
IS_TIMESTAMP_NTZ( <variant_expr> )
IS_TIMESTAMP_TZ( <variant_expr> )
ExamplesΒΆ
Get all timestamp_ltz values in a variable column, output using the timezone specified for the session.
Note
The output format for timestamp_ltz values is set using the TIMESTAMP_LTZ_OUTPUT_FORMAT parameter. If not specified, the default is
to use the TIMESTAMP_OUTPUT_FORMAT parameter setting. The default setting for this parameter is YYYY-MM-DD HH24:MI:SS.FF3 TZHTZM
.
In this example, the local time zone is US Pacific Standard Time (-08:00 relative to GMT/UCT).
Create and load the table:
create or replace table vardttm (v variant);BEGIN WORK; insert into vardttm select to_variant(to_date('2017-02-24')); insert into vardttm select to_variant(to_time('20:57:01.123456789+07:00')); insert into vardttm select to_variant(to_timestamp('2017-02-24 12:00:00.456')); insert into vardttm select to_variant(to_timestamp_ltz('2017-02-24 13:00:00.123 +01:00')); insert into vardttm select to_variant(to_timestamp_ntz('2017-02-24 14:00:00.123 +01:00')); insert into vardttm select to_variant(to_timestamp_tz('2017-02-24 15:00:00.123 +01:00')); COMMIT WORK;
Show the TIMESTAMP
values in the data:
