Re: [despammed] How to get day of week?

I'm sure I'm missing something obvious, but this is the novice list, so
here goes:

Is there a function to return the day-of-week for a given time/datestamp?

What I'm looking for is something like:

select day(current_timestamp);

That would return the current day of the week (e.g. Monday/Tuesday...)

Thanks,

-Lloyd

You search something like this:

select extract(dow from eingang) from a_buch ;
^^^^^^^^^^^^^^^^^^^^^^^^^

See also to_char() in the "Data Type Formatting Functions" section
of the "Functions and Operators" chapter in the documentation.

SELECT to_char(CURRENT_DATE, 'D,Dy,Day');
to_char
-----------------
3,Tue,Tuesday

Note that to_char() and extract() use different numbering for the
day of the week.

The function you're looking for is to_char(), and it has tons of options.
