IBM DB2 SQLCODE -551: Authorization Failure (Missing SELECT Privilege)
What it means: SQLCODE -551 is an authorization error in IBM DB2, indicating that the current user or application lacks the necessary privileges to perform a specified operation on one or more database objects. In your case, “missing select privilege” highlights a lack of SELECT access, meaning the user can’t query (read) the targeted table, view, or database object.
Common causes:
- The user isn’t granted the SELECT privilege on the object (e.g., via
GRANT SELECT ON table_name TO user_name). - Use of a shared connection with restricted roles or insufficient authority.
- Attempts to query system objects or restricted views without proper permissions.
- Issues with implicit privileges (e.g., through roles or groups that don’t include SELECT).
How to diagnose:
- Check the full error message in logs or from
db2 diag/db2 ? SQLCODE -551for specifics on the objected affected. - Verify user privileges using DB2 commands like
db2 "GET AUTHORIZATIONS"or querying syscat tables (e.g., SYSCAT.TABAUTH for table privileges).
Resolution steps:
- Grant privileges: An administrator should run
GRANT SELECT ON object_name TO user_name [WITH GRANT OPTION](replace with actual object and user). - Check roles/groups: Ensure the user is in a group or role with SELECT access.
- Test with elevated access: If using DB2 CLP, connect as a privileged user (e.g., DBADM).
- Review security policies: Consult DB2 security docs (IBM Knowledge Center) for role-based access control (RBAC) configurations.
- If persistent, restart DB2 or audit connection settings.
This error prioritizes security, preventing unauthorized data access. For complex setups, escalate to your DBA. Reference: IBM DB2 SQL Messages and Codes manual.
