Hi there, i'm new to postgres. I want to create view when adding new row. So what i've got:
CREATE OR REPLACE FUNCTION add_view() RETURNS trigger AS $$ DECLARE someint integer; BEGIN RAISE NOTICE 'dodajesz nowa lige %', NEW.id; someint := NEW.id; RAISE NOTICE 'dodajesz nowa lige %', someint; CREATE VIEW tabelka AS SELECT * FROM t_matches.someint; RETURN NULL; END; $$ language plpgsql;
CREATE TRIGGER league AFTER insert ON t_leagues FOR STATEMENT EXECUTE PROCEDURE add_view();
Then in psql I made an query and got error:
league=# INSERT INTO t_leagues (name) VALUES('3liga'); ERROR: record "new" is not assigned yet DETAIL: The tuple structure of a not-yet-assigned record is indeterminate. CONTEXT: PL/pgSQL function "add_view" line 4 at RAISE
Whats wrong, I supposed that id is not reserverd at the moment, so what can I do?
And here is some infos about table
league=# \d t_leagues Table "public.t_leagues" Column | Type | Modifiers ------------+-----------------------+-------------------------------------------------------- id | integer | not null default nextval('t_leagues_id_seq'::regclass) name | character varying(20) | not null data_start | date | data_end | date | awans | smallint | not null default 0 baraz | smallint | not null default 0 spadek | smallint | not null default 0 Indexes: "t_leagues_pkey" PRIMARY KEY, btree (id) Triggers: league AFTER INSERT ON t_leagues FOR EACH STATEMENT EXECUTE PROCEDURE add_view()
