Hi everyone, here is my problem :
I got two tables :
CREATE TABLE "public"."calendar_temp" (
"id" SERIAL,
"dat" DATE,
"heur" TIME WITHOUT TIME ZONE,
CONSTRAINT "calendar_temp_pkey" PRIMARY KEY("id")
) WITHOUT OIDS;
CREATE TABLE "public"."h_part" (
"idh" SERIAL,
"poste_idposte" INTEGER NOT NULL,
"t" NUMERIC(4,1),
"heuremesure" TIME WITHOUT TIME ZONE,
"datmesure" DATE,
CONSTRAINT "h_part_datmesure_key" UNIQUE("datmesure", "heuremesure", "poste_idposte"),
CONSTRAINT "h_part_pkey" PRIMARY KEY("idh"),
CONSTRAINT "h_part_fk" FOREIGN KEY ("poste_idposte")
REFERENCES "public"."poste"("idposte")
ON DELETE NO ACTION
ON UPDATE NO ACTION
NOT DEFERRABLE
) WITHOUT OIDS;
Data in table are like this :

LEFT OUTER JOIN h_part as hp

Hi, Thomas.
I believe it is because of your WHERE clause, which is filtering out the nulls from hp table.
According to
WHERE
hp.poste_idposte = 275
You only want registers that have hp.poste_idposte = 275, not the null ones.

Oliveiros

Try moving the hp.poste_idposte=275 inside the LEFT JOIN condition, somethin like :
SELECT ct.dat,ct.heur,hp.datmesure,hp.heuremesure,hp.t FROM calendar_temp as ct
LEFT OUTER JOIN h_part as hp
ON (ct.dat = hp.datmesure
AND ct.heur = hp.heuremesure
AND hp.poste_idposte = 275)
ORDER BY ct.dat, ct.heur
And drop the WHERE clause.
See if it gives the results you intended.
Best,
Oliveiros

Yes, the WHERE effectively turns the outer into an inner join, thus
removing rows from the right table. By moving the WHERE to the JOIN
condition, you get the result you expected.

you have to consider the where condition. In those lines where you
expect null values, he poste_idposte field would be null as well.
for example, the following query returns the expected result :
SELECT ct.dat,ct.heur,hp.datmesure,hp.heuremesure,hp.t
FROM calendar_temp as ct LEFT OUTER JOIN h_part as hp
ON ct.dat = hp.datmesure
AND ct.heur = hp.heuremesure
WHERE
coalesce(hp.poste_idposte,275) = 275
ORDER BY ct.dat, ct.heur;
