I wanna to DROP a table called EMPLOYEES, but when I execute the DROP TABLE EMPLOYEES, I get a ERROR saying that I cant do it because this table do reference to another table(s).
I tried to use the DBA_CONS_COLUMNS and DBA_CONSTRAINTS data tables, but its not enough to find it.
How can I find these references?
which data dictionary should i choose to see the foreign key and primary key of table
View 2 Replies View RelatedIn my database I found some anomalies like
SQL> select SEGMENT_NAME, SEGMENT_TYPE, BLOCKS, EXTENTS, BYTES/1024
2 from user_segments
3 where SEGMENT_TYPE='TABLE'
4 ORDER BY SEGMENT_NAMe;
[code]....
The countries table is missing in user_segments data dictionary view.But I can queries the countries using select statement.
SQL> SELECT * FROM COUNTRIES;
CO COUNTRY_NAME REGION_ID
-- ---------------------------------------- ----------
AR Argentina 2
AU Australia 3
BE Belgium 1

[code]...
why the country table is missing in user_segments data dictionary table.
Is there any oracle dictionary view which captures the queries being run by users on the database and time taken to execute those queries?We need to find out the OS user not the database user since we have to identify the users who are executing long running queries.We require this basically to monitor the long running queries on the database.

Quote:To check whether an existing procedure is compiled for native execution or not, you can query the following data dictionary views:
[USER | ALL | DBA]_STORED_SETTINGS
[USER | ALL | DBA ]_PLSQL_OBJECTS
However, I when i query the view USER_PLSQL_OBJECTS I get the following error message:
Quote:ORA-00942: table or view does not exist
Question 2) I have read the PLSQL_WARNING can be set to DEFERRED at the system level. However, I am unable to defer it. tell me how to apply defer caluse to following statement:

Some DBA_views are huge with lots of columns ; a DESC command's output becomes less readable ; example DESC command's output of V$SESSION view.
Lets say I want to see only the date columns in a DBA_view or V$view ; How can I do that in a DESC like output or similair ?
In order to improve the performance of our live server, I am trying to do an exhaustive comparison with our test environment which is quite quick in spite of the fact that we port the data from Live every month.
There are no obviously slow queries appearing in the the top SQLs of AWR, we have optimised such things already. Right now it is about general uplift rather than SQL based tuning.
I picked up random SQLs and I noticed a marked differences in the execution time. Typically they are 3 to 4 times and there are cases much more than that.
1. I observed that, while the explain plan of the queries are same, trace of the queries give a different picture. I have observed that the recursive calls, consistent gets and sorts(memory) are quite high on Live.
2. I have no solid reasons to say this but my instincts tell me that the recursive calls is the major contributing factor. It is sometimes 2000+ for an SQL.
3. On googling more on that, it finally made me compare the data dictionary on the AWR report of test and Live.
The dc_objects caught my eyes. In that 4 hour AWR, there were about 10 million get requests and the pct miss was ~10. For similar load, the test server had 5 million gets with 0.08 PCT miss for 4 hours.
I have to create six tables as part of my assignment. I have created 5 tables. I am having trouble with the 6th. How can I reference a foreign key to a composite primary key? I have colored red the areas that I think are giving me trouble which is in the 6th table, the Registration Table.

i have inner query result like

I'm having a problem with grouping sets over dictionary views.
10g output:
SQL> select
2 -- 10g results
3 segment_name,
4 round(sum(bytes/1024/1024),2) mb
5 from dba_segments
[Code]...
ERROR at line 10: ORA-03001: unimplemented feature
Elapsed: 00:00:00.12
The query is fine over a non-dictionary table however (My actual code isnt against dual, but this makes it generic, the error is consistent)
11g output
SQL> select
2 -- 11g results
3 segment_name,
4 round(sum(bytes/1024/1024),2) mb
5 from dba_segments
[Code]....
ERROR at line 8: ORA-00904: : invalid identifier
Different error and that syntax, as far as I can tell, is sound - error message be damned.
An example of a query working on both versions is
select
employee_id,
sum(salary)
from
employees
group by grouping sets ((employee_id),null)
;
Am I missing something? Does grouping sets not work over the dictionary views?
Edit: Added version tags over the code to make it easier to read
