I have two columns, date
and time
, both strings. I can concatenate them to get a column timestamp
.
I need to use the timezone_minute()
function † . I have tried various formats for the parameter, but have repeatedly faced the error
Query 1 ERROR: ERROR: function timezone_minute(timestamp without time zone) does not exist
LINE 1: select timezone_minute('2023-01-25T05:36:48Z'::date AT TIME ...
^
HINT: No function matches the given name and argument types. You might need to add explicit type casts.
For example
-- function timezone_minute(timestamp without time zone) does not exist
select timezone_minute('2023-01-25T05:36:48Z'::date AT TIME ZONE 'UTC');
-- function timezone_minute(timestamp with time zone) does not exist
select timezone_minute('2023-01-25T05:36:48Z'::date AT TIME ZONE 'UTC');
select timezone_minute('2023-01-25T05:36:48Z'::timestamptz);
select timezone_minute(cast('2023-01-25T05:36:48Z' as TIMESTAMP));
-- etc
How do I correctly utilise timezone_minute - the documentation is severely lacking for this particular function, unfortunately.
† I don't fully control the final query, hence the need to use this function. The generated query utilises timezone_minute(), I can essentially set the argument.
the documentation is severely lacking for this particular function, unfortunately.
Yes, because it's not a function.
It is an argument to the extract()
function :
select extract(timezone_minute from '2023-01-25T05:36:48Z'::timestamptz);
