Hi
I am using PG 8.0 on Win32, learning SQL.
I dod create a table with the following SQL:
CREATE TABLE test (
id integer,
nev varchar(25),
datum timestamp
);
A sequence with:
CREATE SEQUENCE "public"."test_azon_seq"
INCREMENT 1 MINVALUE 101
MAXVALUE 9223372036854775807 START 101
CACHE 1
;
A before insert trigger:
CREATE FUNCTION test_verif() RETURNS trigger AS $test_verif$
BEGIN
NEW.id := select nextval('test_azon_seq');
NEW.nev := nev;
NEW.datum := current_timestamp;
RETURN NEW;
END;
$test_verif$ LANGUAGE plpgsql
;
CREATE TRIGGER test_verif BEFORE INSERT ON test
FOR EACH ROW EXECUTE PROCEDURE test_verif()
;
When I issue the
insert into "public"."test" (nev) values ('Graf László');
insert statement, it returns
"ERROR: syntax error at or near "select" at character 9".
Why? What is wrong?

I think you want to remove select here, you're already effectively doing a
select of the right hand side in the assignment.

I think you want to remove this line entirely. What nev were you
expecting on the right hand side? If it's the new one, well, NEW.new is
already that.

László could also remove the entire trigger and use something like
CREATE TABLE test (
id SERIAL NOT NULL,
nev VARCHAR(25),
datum TIMESTAMP NOT NULL DEFAULT current_timestamp,
PRIMARY KEY (id)
);

That's slightly different though. The trigger forces the value whether or
not a value was assigned in the insert, the defaults only apply if the
column does not have a value given to it.
