(scott a les droits sur la table)
create view vscott as select * from emp

ERROR at line 1:

…le droit sur la table sert pour accéder …a la table
connect blake

…Le droit sur la vue suffit

—KING accede a une vue de BLAKE sur une table de SCOTT

connect SYSTEM

SQL> grant select on blake.vblake to king;
Autorisation de privilèges (GRANT) acceptée.
connect KING
select * from blake.vblake
*
ERROR at line 1:
ORA-01031: insufficient privileges

Si on avait tenté de donner les droits en tant que BLAKE
cela aurait été plus clair :
connect blake
grant select on blake.vblake to king
*
ERROR at line 1:
ORA-01720: grant option does not exist for ‘SCOTT.EMP’

LA SOLUTION
connect SCOTT (ou SYSTEM)
grant select on scott.emp to blake WITH GRANT OPTION
