TO_DATE()
and PgSQL extension FROM_CHAR().
TO_CHAR() routine allow formating text output with a datetime values:
SELECT TO_CHAR('now'::datetime, '"Now is: "HH24:MI:SS');
to_char
----------------
Now is: 21:04:10
FROM_CHAR() routine allow convert text to a datetime:
SELECT FROM_CHAR('September 1999 10:20:30', 'FMMonth YYYY
HH:MI:SS');
from_char
-----------------------------
Wed Sep 01 10:20:30 1999 CEST
TO_DATE() is equal with FROM_CHAR(), but output a Date only:
SELECT TO_DATE('September 1999 10:20:30', 'FMMonth YYYY
HH:MI:SS');
to_date
----------
09-01-1999
In attache is compressed dir for the contrib. All is prepared, but I'am
not
sure if Makefile is good (probably yes).
