Hi Mark,

Thanks for the prompt reply. But it seems not working in my installation. I am using Jan2014 release. Is this function available in that bundle?

I got this message when I tried executing the above example.

$ ./bin/mclient -d testdb
Welcome to mclient, the MonetDB/SQL interactive terminal (Jan2014)
Database: MonetDB v11.17.9 (Jan2014), 'mapi:monetdb://vijay-1833:50000/crmdb'
Type \q to quit, \? for a list of available commands
auto commit mode: on
sql>SELECT epoch(1456741924);
SELECT: no such unary operator 'epoch(int)'

Please help me with what I'm missing here. Thanks a ton in advance.

Thanks & Regards,

Hey Vijay,

The function sys.epoch converts an epoch value to a timestamp.

sql>SELECT epoch(1456741924);
+----------------------------+
| epoch_single_value |
+============================+
| 2016-02-29 10:32:04.000000 |
+----------------------------+
1 tuple (1.184ms)

Hope that helps,

Mark

Yes, I have come across this solution, Robin.

But my problem involves converting epoch (a bigint value) into Date or Timestamp.

I went through the Temporal functions page and a few questions in the user thread in the past, but am unable to find a solution till now.

Any help much appreciated.
Thanks & Regards,

Hello,

There might be a way of constructing a timestamp in MonetDB from an epoch, but I can not think of one. Regarding the reference that you gave to unix_timestamp (generating date or times from strings): we have something similar in MonetDB, some examples:
SELECT str_to_date('23-09-1987', '%d-%m-%Y') AS "date",
 str_to_time('11:40', '%H:%M') AS "time",
 str_to_timestamp('23-09-1987 11:40', '%d-%m-%Y %H:%M') AS "timestamp";

+------------+----------+----------------------------+
| date       | time     | timestamp                  |
+============+==========+============================+
| 1987-09-23 | 11:40:00 | 1987-09-23 11:40:00.000000 |
+------------+----------+----------------------------+

Hi,

I am looking for an Epoch (bigint) to date/timestamp converter in MonetDB - something similar to unix_timestamp() in MySQL.

I referred this page - https://www.monetdb.org/Documentation/SQLreference/Temporal and tried out a few functions, but it seems to work only with the existing Timestamp columns.
Am I missing something here?

I am using MonetDB Jan2014 release on a Mac OS-X.

Any help much appreciated.
