Can you show us the full SQL statement?

You could also use CURRENT_TIMESTAMP - look at the following:

Hi Ray,

yes for sure. Here it is:

SELECT count(*) INTO existing_email FROM cust_portal.tmp_newsletterreg;
if (existing_email <>0) then
{
result = false;
}
else
{
result = true;
INSERT INTO cust_portal.tmp_newsletterreg VALUES
(
nextval( 'tmp_newsletterreg_nlreg_id_seq' ),
email,
session,
SELECT CURRENT_TIMESTAMP;
)
}
end if;

RETURN(result);

thx.

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.

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;
