Date in mmm yyyy format in postgresql

I have a table with a column of type timestamp without time zone.

I want to select that column with the mmm yyyy format – for example, “Mar 2011”. How to format it that way? I tried:

select cast(now() as date)

but it is giving me the incorrect开发者_JAVA百科 format.

SELECT TO_CHAR(NOW(), 'Mon YYYY');

DateAndTime Reformat:

SELECT *, to_char( last_update, 'DD-MON-YYYY') as re_format from actor;

DEMO:

I think in Postgres you can play with formats for example if you want dd/mm/yyyy

TO_CHAR(submit_time, 'DD/MM/YYYY') as submit_date

You need to use a date formatting function for example to_char http://www.postgresql.org/docs/current/static/functions-formatting.html

You can write your select query as,

select * from table_name where to_char(date_time_column, 'YYYY-MM')  = '2011-03';
