Unveiling Your Database Toolkit: Exploring Objects Owned by a User in Oracle

In the intricate world of database management, understanding the landscape of objects is crucial for efficient operation. This blog post empowers you to leverage a specific Oracle Database SQL code snippet to list all objects owned by a particular user. This knowledge equips you to navigate user privileges, manage object dependencies, and gain valuable insights into your database's structure.

Sample SQL Command

1col object_name format a40
2select object_name
3,      object_type
4from dba_objects
5where owner = '&user'
6order by object_type, object_name

Sample Oracle Output:

 1Enter value for user: ANDY
 2old   4: where owner = '&user;'
 3new   4: where owner = 'BILL'
 5OBJECT_NAME                              OBJECT_TYPE

2921 rows selected.


This SQL code snippet serves the vital purpose of retrieving a list of all objects belonging to a specific user within the Oracle database. It accesses information from the dba_objects view, a virtual table containing metadata about various database objects.


  • col object_name format a40: This line configures the output column named object_name to display data in a 40-character wide format, enhancing readability.
  • select object_name: This clause selects the object_name column from the query results, displaying the names of the objects.
  • object_type: This column selection retrieves the object_type information, revealing the type of object (e.g., TABLE, VIEW, PROCEDURE).
  • from dba_objects: This clause specifies the dba_objects view as the source of data for the query.
  • where owner = '&user': This line filters the results based on the user name, denoted by the &user parameter. This allows you to specify the target user for whom you want to list the objects.
  • order by object_type, object_name: This clause sorts the results in a user-friendly manner, first by object type (e.g., tables, views, procedures) and then alphabetically by object name.

Key Points and Insights:

  • This code snippet is valuable for various scenarios:
    • Identifying user privileges: By understanding a user's owned objects, you can gauge their potential access and capabilities within the database.
    • Managing object dependencies: Understanding object ownership can assist in identifying potential dependencies between objects, aiding in impact analysis and change management.
    • Gaining insights into database structure: Analyzing the types and names of owned objects provides a foundational understanding of the database's overall organization.
  • Remember: This code requires the necessary system privileges to access the dba_objects view. Consult your database administrator for details.
  • Beyond the code snippet: While this script is a valuable tool, its application extends beyond the results it provides. Consider these additional factors:
    • User roles and permissions: User ownership alone might not fully depict user access. Explore user roles and granted privileges to gain a clearer picture.
    • Object dependencies: Investigate dependencies between objects to understand potential impacts of changes or modifications.
    • Documentation and best practices: Maintain clear object descriptions and adhere to established coding standards for optimal database management.

By effectively utilizing this code snippet and considering the broader context, you can gain valuable insights into user ownership, manage object interactions, and contribute to a well-organized and efficient Oracle database environment.
