User Action:
If a reference name was specified for a table name, use this reference name in the SQL statement.
If the <FROM clause> contains the specification of a table which does not belong to the current user, to this user's user class or DBA, and which is not a system table, the <OWNER> must be specified for the table throughout the SQL statement.
