G-1060: Avoid storing ROWIDs or UROWIDs in database tables.

Major

Reliability

Reason

It is an extremely dangerous practice to store ROWIDs in a table, except for some very limited scenarios of runtime duration. Any manually explicit or system generated implicit table reorganization will reassign the row's ROWID and break the data consistency.

Instead of using ROWID for later reference to the original row one should use the primary key column(s).

Example (bad)

BEGIN
   INSERT INTO employees_log (employee_id
                             ,last_name
                             ,first_name
                             ,rid)
   SELECT employee_id 
         ,last_name
         ,first_name
         ,ROWID
     FROM employees;
END;

Example (good)

BEGIN
   INSERT INTO employees_log (employee_id
                             ,last_name
                             ,first_name)
   SELECT employee_id 
         ,last_name
         ,first_name
     FROM employees;
END;
