Si instruction dans select (Oracle)

Salut, j'ai simplement sélectionner et fonctionne très bien:

select 'CARAT Issue Open' issue_comment, i.issue_id, i.issue_status, i.issue_title, i.ISSUE_summary ,i.issue_description, i.severity,
gcrs.Area_name, gcrs.sector_name,

substr(gcrs.stream_name,1,case when instr(gcrs.stream_name,' (')=0 then 100 else instr(gcrs.stream_name,' (')-1 end) ISSUE_DIVISION,

case when gcrs.STREAM_NAME like 'NON-GT%' THEN 'NON-GT' ELSE gcrs.STREAM_NAME END as ISSUE_DIVISION_2


from table(f_carat_issues_as_of('31/MAR/2013')) i
inner join v_gcrs_with_stream gcrs on i.segment_id = gcrs.segment_id

where UPPER(ISSUE_STATUS) like '%OPEN%'

Maintenant, je veux appeler deux colonnes: ISSUE_DIVISION et ISSUE_DIVISION_2

si elles sont égales dans les nouvelles colonnes, la valeur 1 si non égales, la valeur 0,

comment puis-je le faire ? 

mon code complet:

select 'CARAT Issue Open' issue_comment, i.issue_id, i.issue_status, i.issue_title, i.ISSUE_summary ,i.issue_description, i.severity,
gcrs.Area_name, gcrs.sector_name,

substr(gcrs.stream_name,1,case when instr(gcrs.stream_name,' (')=0 then 100 else instr(gcrs.stream_name,' (')-1 end) ISSUE_DIVISION,

case when gcrs.STREAM_NAME like 'NON-GT%' THEN 'NON-GT' ELSE gcrs.STREAM_NAME END as ISSUE_DIVISION_2


from table(f_carat_issues_as_of('31/MAR/2013')) i
inner join v_gcrs_with_stream gcrs on i.segment_id = gcrs.segment_id

where UPPER(ISSUE_STATUS) like '%OPEN%' and 

CASE WHEN ISSUE_DIVISION = ISSUE_DIVISION_2 THEN 
     CASE WHEN  ISSUE_DIVISION is null then "Null Value found"
     Else 1 End
ELSE 0 END As Issue_Division_Result

mais je reçois une erreur en ligne: ELSE 0 END As Issue_Division_Result

ORA-00920: opérateur relationnel non valide :(

Si simple que vous pouvez utiliser case statement ici.

CASE WHEN ISSUE_DIVISION = ISSUE_DIVISION_2 THEN 
         CASE WHEN  ISSUE_DIVISION is null then "Null Value found" //give your option
         Else 1 End
ELSE 0 END As Issue_Division_Result

si vous utilisez la variable, Oracle ne prend pas en charge SQL dans ce contexte sans INTO. Avec une variable bien nommée, votre code sera de toute façon plus lisible.
