Changes
After successful Rename of a virtual column all requests on the table
SELECT, MODIFY, RENAME, DROP virtual columns receives a ORA-00904. The
virtual column depends on typed columns:
E.g.:
create table t1_test
(
a tr_test,
b tr_test,
s integer generated always as ( a.x + b.x ) virtual
);
If the column "a" is renamed then the virtual column expression is not
automatically updated and the old reference is used, therefore the ORA-904
error.
