Query com valores null

Question

Olá

Estou com um problema nesta query

SELECT 
COALESCE(id_tempo, 0) AS id_tempos
,`semana_dias`.`dia`
, `req_material_sala`.`sala`
, `req_material_tempo`.`inicio`
FROM sala_ocupacao 
INNER JOIN `semana_dias` ON (`sala_ocupacao`.`id_dia` = `semana_dias`.`id_dia`)
INNER JOIN `req_material_sala` ON (`sala_ocupacao`.`id_sala` = `req_material_sala`.`idsala`)
INNER JOIN `req_material_tempo` ON (`sala_ocupacao`.`id_tempo` = req_material_tempo.`idtempo`)
ORDER BY id_ocup;

Mas só me dá os registos que não tem null por causa desta última parte

INNER JOIN `req_material_tempo` ON (`sala_ocupacao`.`id_tempo` = req_material_tempo.`idtempo`)

Como posso fazer para me dar todos incluindo os null

Obrigado

Onde está

INNER JOIN `req_material_tempo` ON (`sala_ocupacao`.`id_tempo` = req_material_tempo.`idtempo`)
escreva
LEFT JOIN `req_material_tempo` ON (`sala_ocupacao`.`id_tempo` = req_material_tempo.`idtempo`)
