EXCEPT en SQL permet d’extraire les diff\u00e9rences entre 2 tables.

Exemple : 2 tables article avec des contenus diff\u00e9rents<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n


1) Extraire les lignes de ARTICLE qui ne sont pas dans ARTICLE2 :
SELECT<\/strong> * FROM<\/strong> article
EXCEPT<\/strong>
SELECT<\/strong> * FROM<\/strong> article2<\/code>
R\u00e9sultat :<\/mark> Casquette jaune<\/strong><\/mark><\/p>\n\n\n\n

2) Extraire les lignes de ARTICLE2 qui ne sont pas dans ARTICLE :
SELECT<\/strong> * FROM<\/strong> article2
EXCEPT<\/strong>
SELECT<\/strong> * FROM<\/strong> article<\/code>
R\u00e9sultat :<\/mark> Beret noir<\/strong><\/mark><\/p>\n\n\n\n

3) Il est possible de comparer sur une ou plusieurs colonnes choisies.
Par exemple, extraire les couleurs de ARTICLE2 qui ne sont pas dans ARTICLE :
SELECT<\/strong> couleur FROM<\/strong> article2
EXCEPT<\/strong>
SELECT<\/strong> couleur FROM<\/strong> article<\/code>
R\u00e9sultat :<\/mark> noir<\/strong><\/mark><\/p>\n\n\n\n

<\/p>\n\n\n\n

A noter, il est possible de comparer 2 fichiers source avec EXCEPT :
1- OVRDBF FILE(SOURCE1) TOFILE(BIB1\/QRPGSRC) MBR(PGM1)
2- OVRDBF FILE(SOURCE2) TOFILE(BIB2\/QRPGSRC) MBR(PGM2)
3- SELECT * FROM<\/strong> source1 EXCEPT<\/mark><\/strong> SELECT * FROM<\/strong> source2<\/p>\n\n\n\n
