Обсуждение: Date format
Hi, I have two fields of column type 'date' from which I want to output a formatted date (with PHP). I understand that MySQL would use DATE_FORMAT and appropriate %M, %D commands. I am having trouble finding the equivalent PostgresQL commands. I am using PG 7.3.4. I have found the template patterns for the conversions. I want it to be in this format: Day, DD Month YYYY I do not know the function to format this so. if to_date() converts a string to date, what converts/formats date to string? Thankyou very much. -Dylan Fogarty-MacDonald dylan.fm@gmail.com

These include patches to security flaws and data-loss-incurring bugs. 8.1.4 will most likely perform much better for you as well. > if to_date() converts a string to date, what converts/formats date > to string? I think you'll want to look at TO_CHAR: http://www.postgresql.org/docs/current/interactive/functions- formatting.html I've found it useful to use EXTRACT(EPOCH FROM your_timestamp) to pass the timestamp to PHP, and then use the PHP timestamp formating functions. http://www.postgresql.org/docs/current/interactive/functions- datetime.html#FUNCTIONS-DATETIME-EXTRACT Hope this helps.

If you are using PHP, then as Michael mentioned, you can either use the
Postgres to_char function to return the date formatted in the SQL query, or
use the PHP date() function to format it. Eg:
SQL:
to_char('01-07-2005', Day, DD Month YYYY') AS "Date"
Returns:
Friday , 01 July 2005
PHP:
date('L, d F Y', mktime(0, 0, 0, 07, 01, 2005))
Returns:
Friday, 01 July 2005
Note the extra spaces in the SQL version. They are padded out to the maximum
possible length of that string - ie, Friday is padded out to the number of
characters in 'Wednesday' - That's my understanding anyway; Someone care to
correct me?
Cheers,

Hi,
I have two fields of column type 'date' from which I want to output a
formatted date (with PHP).
I understand that MySQL would use DATE_FORMAT and appropriate %M, %D
commands.
I am having trouble finding the equivalent PostgresQL commands. I am
using PG 7.3.4.
I have found the template patterns for the conversions. I want it to be
in this format:
Day, DD Month YYYY
I do not know the function to format this so.
if to_date() converts a string to date, what converts/formats date to
string?
Thankyou very much.

Thankyou very much.
I tried with PHP date() but I had a few problems.
I ended up using the SQL, and it works as this in the query:
to_char(project_enddate, 'Day, DD Month YYYY') AS enddate,
to_char(project_startdate, 'Day, DD Month YYYY') AS startdate
In regards to upgrading to the latest Pgsql - I would love that but I am
not running the server, I can suggest the upgrade but I do not know if
that will occur.
Luckily I am setting up a couple of servers in my spare time at work, so
eventually I can use them.
Thanks again,
