Important

The SingleStore 9.1 release candidate (RC) is available now. It will be promoted to general availability (GA) soon and at that time it will be renamed to SingleStore 10.

In the interim, SingleStore 9.1 RC can be used to preview, evaluate, and provide feedback on the new and upcoming features in SingleStore 10, while SingleStore 9.0 is recommended for production workloads.

TIMESTAMP

On this page

The TIMESTAMP() function converts the input argument to a datetime object.

Syntax

TIMESTAMP(dateobj)

Arguments

  • dateobj: a valid date, datetime, or parsable date string.

Return Type

Datetime object. If dateobj is not a valid date, returns NULL.

Remarks

  • TIMESTAMP is based on UTC timezones.

  • SingleStore converts TIMESTAMP values from the current timezone to UTC for storage.

  • Minimum value: when setting a value for TIMESTAMP, if your UTC timezone is before UTC (set to UTC +<hours>) and you set TIMESTAMP to its minimum value (1970-01-01 00:00:01), the query will insert 0000-00-00 00:00:00.

  • The TIMESTAMP function supports improved segment elimination when used in WHERE clauses. See the following query example:

    SELECT ... FROM table_name WHERE TIMESTAMP(column_name) > '2000-01-01 00:00:00' AND TIMESTAMP(column_name) <= '2015-03-03 00:00:00';

Examples

SELECT TIMESTAMP('2015-03-03');
+-------------------------+
| TIMESTAMP('2015-03-03') |
+-------------------------+
| 2015-03-03 00:00:00     |
+-------------------------+
