Hi,

i have a stored procedure (a function) in which i must generate a date/time
stamp.
for that i use "select * from now();" and store the result into a column
table.

is there a easier way to do that ? i tried to store directly now(); result
but without success.

thx.

Can you show us the full SQL statement?

You could also use CURRENT_TIMESTAMP - look at the following:

http://www.postgresql.org/docs/8.3/s...TETIME-CURRENT

HTH,

Hi Ray,

yes for sure. Here it is:

If you want the timestamp on INSERT add DEFAULT now() to column.
In a pl/pgsql function I do;

new.ts_update:=now()

where ts_update is the column I am updating.
Be aware now() records the time at the beginning of the transaction. An
alternate is clock_timestamp() which records the current time.

That should be

INSERT INTO cust_portal.tmp_newsletterreg VALUES
(
nextval( 'tmp_newsletterreg_nlreg_id_seq' ),
email,
session,
CURRENT_TIMESTAMP
)

There is no SELECT and no semicolon inside the INSERT

Hi Alain,

That won't work; you just need

... values (.... email, session, CURRENT_TIMESTAMP)

CURRENT_TIMESTAMP is a function, so it's return value will be used where
it appears.

What procedural language are you using? If it's pl/pgsql then the curly
brackets aren't needed, nor are the parentheses in the return statement.
Also, there's a semi-colon missing after the INSERT statement, which may
or may not cause problems.

Ray.

So thanks a lot to everybody... so here is the result.

1. the semicolon was missing after the INSERT as wrote Raymond.
2. CURRENT_TIMESTAMP works great
3. i use pl/pgsql as language

thanks again.
Alain

Do you mean something like this:

CREATE OR REPLACE FUNCTION "public"."test"()
RETURNS timestamp AS
$BODY$
DECLARE
mydate_var timestamp;

BEGIN
--store the current timestamp in a variable
mydate_var = now();

RETURN mydate_var;


END;
$BODY$
LANGUAGE 'plpgsql' VOLATILE;
