View loses its grants when modifying

Question

Is it normal for an oracle view to loose all its grants when modifying the source SQL? I am using SQL Developer if that has anything to do with it.

Answer 1

First of all, you don't have "grants" - "grant" is an operation. You have "roles" and "privileges".

Second, views have neither roles nor privileges themselves - schemas do have. Basically, a self-descriptive command is: grant select on view_1 to schema_1.

Third, schemas do not lose their privileges if you create or replace your view. Here's a quick sample:

11:03:07 @> conn system/sys@oars_sandbox

However, it is quite possible that SQL developer invokes drop view first instead of create or replace. In this case, your privileges are automatically removed.

11:05:26 SYSTEM@oars_sandbox> drop view test1.view1;                                                                            

View dropped.
