Question : Data Access Security

Does Oracle support data access restriction based on time? For example, is there a way to make certain tables/views read/write accessible to some user accounts only during business hours?

Answer : Data Access Security

check SYSDATE or SYSTIMESTAMP.

for business hours,  I think SYSDATE would be sufficient


your policy function might be something like...  if sysdate between 8am and 5pm then ok

which, in pl/sql might be a predicate something like....

return (SYSDATE >= trunc(sysdate) + 8/24  and SYSDATE <= trunc(sysdate)+ 17/24)
