DBA VIEWS CONSTRAINTS

Hi Folks
In which DBA view I found the reference between tables, example:
I have three tables (emp,dept,sal) the emp has a primary key that is referenced by the tables dept and salary, but I only know the primary key name where I want to know the tables that reference the emp table?
Thanks and regards,
Wilson

ALL_CONS_COLUMNS, DBA_CONS_COLUMNS, USER_CONS_COLUMNS
and also for more details -
USER_CONS_OBJ_COLUMNS
ALL_CONS_OBJ_COLUMNS
DBA_CONS_OBJ_COLUMNS
DBA_CONSTRAINTS, ALL_CONSTRAINTS.
Hope this helps

Trigger info in DBA views

In Oracle 8i (and prior), database triggers were not included in DBA_OBJECTS and DBA_SOURCE. As of Oracle 9i, I see that triggers are now included in those views. I thought this was great news, until I had trouble making sense of a particular query. I discovered that most of my triggers, while present in DBA_OBJECTS, were missing from DBA_SOURCE.
Are these views documented in detail somewhere? Is there some legitimate reason that some but not all triggers would be found in DBA_SOURCE?
Thanks in advance for any info you can provide.

How to accesss dba objects (dba views) to find all last ddl times in Apex

Hi,
I want to access all the dba_objects.. all dba_views to find out last ddl's. I installated oracle application express and had created users ADMIN, DEV, both are under XXAPPS schema. How can I find out last ddl's on all db objects. I was not able to pull out objects list from alll schemas's. All schemas are not accesable

I'm not sure why you are trying to do this unless you are intending to build some sort of database monitoring tool, but if you grant the SELECT_CATALOG_ROLE role to the parsing schema, you should be able to see all the DBA_ catalogue views.

Andre

The developer responsible for those views had the following response: "Snapshots is the old name for materialized views introduced in 8i. For materialized view information, please look at the DBA_MVIEWS view. I checked the Oracle doc and verified that DBA_SNAPSHOTS and DBA_SNAPSHOT_LOGS views were documented in Oracle 8, 8i, 9i and removed in 9.2."
Then would it not make sense to put an entry to that effect in the docs:
=========================================================
DBA_SNAPSHOTS
DBA_SNAPSHOTS is the old name for materialized views introduced in 8i. The view is still in the database but has been superseded by DBA_MVIEWS. See also DBA_MVIEWS
=========================================================
I understand that this could (and probably is) now considered an undocumented feature (or undocumented artifact?). It just seems odd that I stumbled across this view and could find no explanation at all. Given that it is a public synonym, I didn't even have to be 'digging' to come across it.
Just out of curiosity, if it has been superseded, is it still maintained for backward compatibility? When would something like that be finally removed from the database, vs. just removing any mention of it from the docs?

Dba views regarding directory and their grant

Hi all,
I want to see users having read, write grant on directories in my database. I am using 10gR2 database. I tried many views but I am not getting the proper view to see the grants(for users) given on directories. how to see this of object privilege? Please suggest...
I have another query. I have few customized roles in my Database. Among them when I am trying to see what roles are granted to that customized role. I used role_role_privs to see the granted role to customized role. It is showing no rows selected. But when I see through TOAD it is showing me two roles are granted to that customized role. Can anybody suggest why is this happening?
Thank you,..

Ora-2270 Error while adding foreign key constraint on top a view

While adding a constraint, referencing a foreign key column from a view raises error. However, it works fine over a table.

create view tempvw as select sample_id,text from t_temp;

thank you

luis,
I don't understand why your mv failed, but I tried it in a way I would do it, using an empty MV rather than one with a single rwos with 0 in it. i.e.:
create materialized view prd_type_val_prd_class
refresh fast on commit
as
select pt.product_type_id
      ,pc.product_type_id pc_bc_product_type_id
      ,pc.product_class_id
      ,pc.rowid pc_row_id
      ,pt.rowid pt_row_id
from product_type pt
   , product_class pc
where pt.bc_product_type_id = pc.bc_product_type_id
AND pt.move_inv = 'N' and pc.inv_negative = 'Y';and changed the constraint to keep it empty:
alter table prd_type_val_prd_class add constraint rows_in_prd_type_val_prd_class check(1=0);Is it seemed to pass all your tests
