Обсуждение: extracting date FROM timestamp

Hi;
Please. Could you tell me the more simple way to extract the 'date' part of a
timestamp value.
I guess we could extract the year, month, and day subfields and concatenate
them. But, isn't there a more direct way?

Best regards,

Javier

Javier,

Try casting, like so:
select current_timestamp::date;
(note, pgsql won't be able to use an index for a casted field)

Best regards,

Arjen

Hello

tsearch2=# select extract(day from current_timestamp);
 date_part
-----------
        22

or

tsearch2=# select to_char(timestamp 'now','YY DD MM HH12:MI:SS');
      to_char
-------------------
 03 22 12 12:28:46
