I want to give permission to user 'arju' only select permission. Under user arju there are 300 tablse. I want to give only select permission to user arju to all these 300 tables. How I can do this
at a time without explicitly giving individual table (select) permission .

request is not clear .. who owns the tables you are talking about.. ? lets say if X owns the table and then you want to give read only access to y .. you create a role and grant select on all tables to that role and then grant that role to y.

If ARJU owns those tables, he can do anything with them - query them, update, insert records into them, even drop them.

If you'd like to have only SELECT privilege, you'll have to create another user and grant SELECT explicitly for every single table, one by one.

Of course, you won't do that by typing all 300 lines in editor, but use a script which will do that for you; something like this:
SELECT 'GRANT SELECT ON ' || table_name || ' TO newly_created_user;' 
FROM user_tables;

Spool the result of the query into a file and run it at the SQL*Plus prompt.

Ok, Thanks. Then I cant do any operation on arju as he owns the table. I would create another user and run opration. Thanks.

select 'grant select on '||owner ||'.'||object_name||' to test;' "Permission"
from dba_objects
where object_type in ('TABLE', 'VIEW')
AND owner in ('ARJU')

and I have to run output of it.

Is there any way to revoke modify and delete permission of user arju who owns these 300 tables?

Write a database trigger on every table which will prevent you (as the owner) and anyone else to mess up with your tables.

I have done it by spooling grant select...... But by creating role how I can do this?


Step1:create role select_privilege
Step2:grant select on (What will be? here)
Step3:grant select_privilege to user_name;

Step 2 would be the same as if you did that with the newly_created_user - you'd grant SELECT on every single table to that role (instead of a user).

This approach is fine when you plan to create more than one user which is to be granted the same privileges - instead of granting them partially, user by user, you'd simply grant a ROLE to a user.
