Check DB Authority - (DB2 Databases)

In a DB2 database environment, users may be granted different authorities to perform specific operations and access different objects in the database. It is important to check the database authorities of users to ensure that they have the appropriate level of permission to perform the actions they need.

Syntax

To check the database authorities of a user in a DB2 database, the following syntax can be used:

SELECT *
FROM SYSIBMADM.DBAUTH
WHERE GRANTEE = 'username';

Here, username is the name of the user whose authorities are being checked. The SYSIBMADM.DBAUTH system view contains information about the authorization levels of users in a database.

Example

SELECT *
FROM SYSIBMADM.DBAUTH
WHERE GRANTEE = 'bob';

In this example, we are checking the database authorities of a user named bob. The query returns information about the authorization levels of bob, including the objects that they can access and the actions they can perform.

Output

The output of the query will depend on the specific user being checked and their level of authority in the database. The output will contain information about the objects the user can access and the actions they can perform.

Explanation

The SYSIBMADM.DBAUTH system view contains information about the database authorities of users in a DB2 database. By querying this view, we can check the level of authorization of a specific user, including the objects they can access and the operations they can perform within the database.

Use

Checking the database authorities of users is an important step in ensuring that they have the appropriate level of permission to perform the actions they need in the database. By using the SYSIBMADM.DBAUTH system view, users can be granted appropriate access and their authority levels can be checked to ensure that database security is maintained.

Important Points

• Users in a DB2 database may be granted different levels of authority to perform specific operations and access different database objects.
• The SYSIBMADM.DBAUTH system view can be used to check the database authorities of users in a DB2 database.
