Rapport d'erreur :
Erreur SQL : ORA-01752: cannot delete from view without exactly one key-preserved table
01752. 00000 -  "cannot delete from view without exactly one key-preserved table"
*Cause:    The deleted table either had no key perserved tables,
           had more than one key-preserved table, or the key-preserved
           table was an unmerged view or a table from a read-only view.
*Action:   Redefine the view or delete it from the underlying base tables.
