I want to change the object (table) owner to the system, but I did not get any information about this change by looking it up on Google.
How do I change the object owner?
Oracle database version is 21c Express Edition Release 21.0.0.0.0.
Also, can I not view a table created by a common user unless privileges are granted, even if the 'sys' user?
Best regards, Woogie.
Object ownership cannot be changed in Oracle. The object must be recreated.
sys should be able to see anything within the currently connected database context (CDB or individual PDB). Other users will require either explicit grants on the table, or a system privilege like select any table granted within the CDB or individual PDB where the table is located.
Update: Also note that the system account is only a template DBA/privileged account provided by Oracle. It should never own application objects or code. Always put application objects in dedicated (and relatively unprivileged) application schemas.
