Thread: DEFAULT TEXT 'now'
Hi
I´m have a table like bellow:
CREATE TABLE conex (
id int4 PRIMARY KEY DEFAULT NEXTVAL('seq_conex'),
inicio datetime DEFAULT TEXT 'now',
ultimo datetime DEFAULT TEXT
'now',
.
.
.
)
insert into conex (ip) values(´200.200.200.200´)
Will result every time the same data and time for ´inicio´ and ´ultimo´!
I want to insert the current date and time. Is that code correct and the
result a bug???
Is there an way to make the DEFAULT work???
I know I can insert like:
insert into conex (ip, inicio, ultimo) values(´200.200.200.200´, ´now´, ´now´)
but I would like to use DEFAULT.
PostgreSQL 6.4 - Solaris 2.5 sparc
Thank you
Roberto

try:

inicido DATETIME DEFAULT NOW(),
ultimo DATETIME DEFAULT NOW(),

You must type
inicio datetime DEFAULT TEXT now(),
^^^^^
This is the function which calls every time you insert new record. In
your case 'now' is the constant, which calculates once, when you
create the table.

I tried RJLG's example code with 6.4.2, and it worked - I got different times at each insert, so the default 'now' was being calculated at insertion time, not table creation time. Here's what it looks like: test2=> \d conex Table = conex +----------------------------------+----------------------------------+-------+ | Field | Type | Length| +----------------------------------+----------------------------------+-------+ | id | int4 not null default nextval ( | 4 | | inicio | datetime default text 'now' | 8 | | ultimo | datetime default text 'now' | 8 | | ip | inet | var | +----------------------------------+----------------------------------+-------+ Index: conex_pkey test2=> select * from conex; id|inicio |ultimo | ip --+----------------------------+----------------------------+--------------- 1|Tue Mar 23 13:40:24 1999 CST|Tue Mar 23 13:40:24 1999 CST|200.200.200.200 2|Tue Mar 23 13:40:28 1999 CST|Tue Mar 23 13:40:28 1999 CST|200.200.200.202 3|Tue Mar 23 13:40:30 1999 CST|Tue Mar 23 13:40:30 1999 CST|200.200.200.203 4|Tue Mar 23 13:41:06 1999 CST|Tue Mar 23 13:41:06 1999 CST|200.200.200.203 5|Tue Mar 23 13:41:21 1999 CST|Tue Mar 23 13:41:21 1999 CST|200.200.200.205 (5 rows) test2=> ???
