prova questo per generare uno script:
select 'select '||FILE_ID||' FILE_ID,'||
ltrim(sys_connect_by_path('REC_FLD_'||FIELD_NUMBER||' "'||FIELD_NAME||'"',','),',')||
' from RESPONSE_DETAILS where FILE_ID=' ||FILE_ID||';'
from (select t.*,count(*) over (partition by FILE_ID) cnt from RESPONSE_METADATA t)
where cnt=FIELD_NUMBER start with FIELD_NUMBER=1
connect by prior FILE_ID=FILE_ID and prior FIELD_NUMBER=FIELD_NUMBER-1
Aggiunte virgolette doppie perché alcuni nomi di colonna sono riservati "DESC", ad esempio
