1 2 3 | REVOKE ALL PRIVILEGES ON ALL TABLES IN SCHEMA public FROM username; REVOKE ALL PRIVILEGES ON ALL SEQUENCES IN SCHEMA public FROM username; REVOKE ALL PRIVILEGES ON ALL FUNCTIONS IN SCHEMA public FROM username; |
In the example below, we use the following commands to revoke f_user’s all the permissions in table sequences and functions.
1 2 3 | REVOKE ALL PRIVILEGES ON ALL TABLES IN SCHEMA Personel_tablosu FROM f_user; REVOKE ALL PRIVILEGES ON ALL SEQUENCES IN SCHEMA publicsemasi FROM f_user; REVOKE ALL PRIVILEGES ON ALL FUNCTIONS IN SCHEMA publicsemasi FROM f_user; |
We can use the command below to revoke create permission on the schema.
1 | REVOKE CREATE ON SCHEMA public FROM PUBLIC; |
With the help of the command below, we will revoke the select, insert, update, delete permission on the products table from f_user.
Revoke Select Permission from user:
1 | REVOKE SELECT ON products TO f_user; |
Revoke Insert Permission from user:
1 | REVOKE INSERT ON products TO f_user; |
Revoke Update Permission from user:
1 | REVOKE UPDATE ON products TO f_user; |
Revoke Delete Permission from user:
1 | REVOKE DELETE ON products TO f_user; |
To revoke the permissions such as select and insert in the same script, you can edit and run the command by seperating permissions with a comma as follows.
