dependencies on view (how to get invalid)

Hi guys,.

has been read the guide of the notion and came across this

his chapter on pages 157 6-5
under

< data storage considerations >

< i >
Remove indexes on the tables at night to facilitate faster loading data warehouses.
However, all dependent views on the table on which the index is moved becomes invalid.
This means that eventually run no matter what package that reference these abandoned
views will invalidate the package.
Remember that whenever you create a table, index, and display and then delete the index,
all dependent objects on the table are invalidated, including views, packages, package
organs, functions and procedures. This protects the editable join views. < /i >

did a test but does not seem to be what is described above.

Scott@ORCL > create index testidx on dept (dname);
The index is created.

Scott@ORCL > create the display of the view in SELECT * FROM DEPT;
Created view.

Scott@ORCL > DROP INDEX testidx;
The index is deleted.

Scott@ORCL > select the status from useR_objects where object_name = 'VIEW ';

STATUS
-------
VALID

Well, he did not not valid

T1) I missed anything
Q2) which is editable join views. ?

Please advice
Kind regards
Noob

In general, I'd say Yes. But this may be wrong in some particular cases like the package using the session variable and get invalid. See the example Re: block of production database becomes invalid
