Re: [SQL] Partitionning + Trigger and Execute not working as expected

[Sylvain Mougenot]

It works with the answer suggested by Jasen Betts
EXECUTE 'INSERT INTO '|| currentTableName || ' values ($1.*)' USING NEW;

Thank you all for all the help,
and special thanks to Josh Kupershmidt and Jasen Betts (in the order I
received messages)

The full code is

--------------------------- SQL ----------------------
-- Main table
DROP TABLE IF EXISTS job;
CREATE TABLE job (
  idjob serial NOT NULL,
  idjobclient character varying(64) NOT NULL,
  idclient integer NOT NULL,
  idmode integer,
  datecreation timestamp without time zone NOT NULL
);

-- Inherited table
DROP TABLE IF EXISTS job_2011_11;
CREATE TABLE job_2011_11
(
  CONSTRAINT job_2011_11_check_datecreation CHECK (datecreation >=
'2011-11-01 00:00:00'::timestamp without time zone AND datecreation <
'2011-12-01 00:00:00'::timestamp without time zone)
)
INHERITS (job);

-- Trigger to insert in the good table
CREATE OR REPLACE FUNCTION job_insert_trigger()
RETURNS TRIGGER AS
$BODY$
DECLARE
currentTableName character varying := 'job_'
||to_char(NEW.datecreation,'YYYY_MM');
BEGIN
-- Automate table creation
--IF (NOT check_exist_table(currentTableName)) THEN
-- PERFORM add_table_job_yyyy_mm(currentTableName, NEW.datecreation);
--END IF;

EXECUTE 'INSERT INTO '|| currentTableName || ' values ($1.*)' USING NEW;
RETURN NULL;
END;
$BODY$
 LANGUAGE plpgsql VOLATILE
 COST 100;

CREATE TRIGGER job_insert_trg BEFORE INSERT ON job
 FOR EACH ROW EXECUTE PROCEDURE job_insert_trigger();

-- Try to insert datas
INSERT INTO job (idjob, idjobclient, idclient, datecreation) VALUES (1,
'2', 3, '2011-11-16 00:00:00.0');
