Je ne suis pas sûr de ce que vous demandez - s'il vous plaît clarifier la question. –

désolé difficile à expliquer, espérons que cela aide .. – opHASnoNAME

Désolé difficile de répondre :-). Sérieusement, essayez à nouveau de formuler une phrase qui se termine par un point d'interrogation. Et veuillez inclure une instruction create table et insert avec des exemples de données et la sortie attendue. –

Vous ne pouvez pas. Vous pouvez créer un seul sous-ensemble à partir des deux en utilisant une jointure et déplacer le nouveau sous-élément composite de la partie SELECT vers la partie FROM de la requête principale.

Voici une façon d'utiliser start_date et date_fin dans plus d'un endroit

with (select to_date('06/01/2010','MM/DD/YYYY') as start_date, 
      to_date('06/02/2010','MM/DD/YYYY') as end_date 
     from dual) as q1 
select project.id, 
     project_state.state, 
     q1.start_date, 
     q1.end_date, 
     (SELECT SUM((q1.END_DATE - q1.START_DATE + 1) * (WORKLOAD/100)) 
     FROM WORKITEM WHERE PROJECT = PROJECT.ID) AS P_A 
from project 
join project_state on project_state.id = project.state 
join q1 on 1=1
