Is it necessary to specify the cascade constraints option while revoking the granted privileges ?
If suppose there is a table t1 in user's schema A.
User A creates user B. User B creates a table t2 in his schema and making a referential integrity constraint on one of the columns in table t1 of User A.
User B also creates user C. Similarily user C creates a table t3 and makes a referential integrity constraint on one of the columns in table t1 of User A.
Where does the cascade constraint come into picture here while giving a revoke statement only to the user B to deny what it refers on t1 in user A's schema ?
