To revoke the ALTER TABLE permission from a user in Oracle, you need to have the appropriate privileges to revoke permissions. You can revoke specific privileges using the REVOKE statement in Oracle SQL.
The syntax to revoke the ALTER TABLE permission from a user is:
REVOKE ALTER ANY TABLE FROM user_name;
Replace "user_name" with the name of the user from whom you want to revoke the ALTER TABLE permission. After executing this statement, the user will no longer have the privilege to alter any table in the database.
It is important to note that only users with the necessary privileges, such as the system administrator or a user with the GRANT option for ALTER ANY TABLE, can revoke permissions from other users in Oracle.

What is the process for revoking alter table permissions during a database upgrade in Oracle?
- Connect to the Oracle database as a user with the necessary privileges to revoke permissions, such as the DBA user.
- Identify the user or role that currently has alter table permissions that need to be revoked.
- Execute the following SQL statement to revoke the alter table permission:
1
|
REVOKE ALTER ANY TABLE FROM <username or role>;

Replace <username or role> with the actual username or role that needs to have alter table permissions revoked.
- Verify that the alter table permission has been successfully revoked by executing the following SQL query:
1 2 3 |
SELECT GRANTEE, PRIVILEGE FROM DBA_SYS_PRIVS WHERE PRIVILEGE = 'ALTER ANY TABLE'; |
If the user or role still appears in the results of this query, then the permissions have not been successfully revoked.
- Repeat steps 3 and 4 as necessary until all users or roles that need to have alter table permissions revoked have been successfully handled.
- Once all necessary permissions have been revoked, proceed with the database upgrade process.
