Tableau externe - Supprimer le fichier non généré comme prévu

Question

J'ai une table externe avec la définition ci-dessous.

create table app_doctor (
     doc_no    number(9), 
     age    number(3), 
     eor    char(3 char) 
) 
organization external 
( type oracle_loader 
     default directory "DOC" 
     access parameters 
     ( 
     records delimited by newline 
     **load when (eor = "EOR")** 
     string sizes are in characters 
     logfile 'doc.log' 
     badfile 'doc.bad' 
     discardfile 'doc.dsc' 
     fields 
     ( 
      doc_no position  (1:9) integer external(9), 
      age position  (10:12) integer external(3), 
      eor position  (13:15) char(3) 
     ) 
    ) 
     location('HOSP_DOC.txt') 
) 
reject limit unlimited 
parallel 5; 

I nourrir 100 dossiers, dont 50 sont valides, 20 ne sont pas valides, et 30 ne satisfait pas à la condition WHEN, mais je ne vois que 4 ou 5 dossiers dans mon dossier de défausse.

Utilisation de la définition de la table externe suivante:

create table app_doctor (
     doc_no    number(9), 
     age    number(3), 
     eor    char(3 char) 
) 
organization external 
( type oracle_loader 
     default directory "DOC" 
     access parameters 
     ( 
     records delimited by newline 
     **load when (eor = "EOR")** 
     string sizes are in characters 
     logfile 'doc.log' 
     badfile 'doc.bad' 
     discardfile 'doc.dsc' 
     fields 
     ( 
      doc_no position  (1:9) integer external(9), 
      age position  (10:12) integer external(3), 
      eor position  (13:15) char(3) 
     ) 
    ) 
     location('HOSP_DOC.txt') 
) 
reject limit unlimited 
parallel 5; 

Et le fichier de données de test suivant:

 
123456789021EOR 
123456789021EOR 
123456789021EOR 
123456789021EOR 
123456789021FER 
123456789021FER 
123456789021FER 
asdfasfa9021ABC 
asdfasfa9021ABC 
asdfasfa9021ABCasdfasdas 
123456789021ABC 
123456789021FER 
123456789021EOR 
123456789021EOR 
123456789021EOR 
123456789021ABC 
123456789021ABC 
123456789021ABC 

Je reçois 7 enregistrements valides retournés lors de l'exécution

select * from app_doctor; 

Mon fichier défausse contient tous les 11 enregistrements incorrects et le fichier journal doc.log contient le correct inf ormation ce qui est arrivé lors de l'exécution:
