All_dependencies

If I want to know mytable is used in a select or insert everywhere across the database,
I do not have access to dba_dependencies, Is the below correct ?
I just need to know the dependent objects for mytable
select name||'-->'||owner||'-->'||type||'-->'||REFERENCED_NAME||'-->'||REFERENCED_TYPE||
'-->'||REFERENCED_OWNER
from all_dependencies
where lower(NAME) like LOWER('%mytable%')
and owner not in ('SYS','SYSTEM')
order by name

Add a predicate 'and type = 'TABLE' if you only care about a table.
And I suggest you start by just querying the view itself until you know you are getting the data you want. Then you can start concatenating everything together if you need to.
Your query produces such a jumbled set of data it's hard to tell if it has the info you need. Start with
select * from all_dependencies
where lower(NAME) like LOWER('%employees%')
and owner not in ('SYS','SYSTEM')
and type = 'TABLE'
order by name

How to get the List of Database Objects (Table/View) for a given APEX Page.

Hi,
I have an application and that consist of pages like page1,2,3,.....
*1.* I want a report which can give me the list of all the Pages1,2,3,....
I am using the following query to acheive this.... THIS IS FINE..
select a.workspace, a.owner, a.application_name, b.page_id, b.page_name
from apex_applications a,
apex_application_pages b
where a.workspace = b.workspace
and a.application_id = b.application_id*2. Now, I want for each individual page*, the list all the database objects (tables/views), which that page is using.
I am using ALL_DEPENDENCIES , but I am not getting the result.
So, want to know if there any view/table, where I can get the Application Pages & there database object list...
Thanks,
Deepak

Hari,
Thanks for the response.
The view APEX_APPLICATION_PAGE_DB_ITEMS will only give me the table name related to any Page Items defined to that page..It will not give me all the database objects..
suppose we have a Page, having a report based on multiple tables and there is no Page items defined on that page, we will not have any value in this ....DB_ITEMS table. same thing if we have define some PL|SQL(using some table/view) in a Process, that will not be populated in .....DB_ITEMS table. I want some thing like all the database objects (table/views/function/procedure/.....) for a particular Page ID.
Thanks,
Deepak

Question on Synonyms and Implicit Cursor

Hi,
I've two doubts.
Question1:
Why Oracle is allowing me to create a synonym even base object does not exist in database.
For example in below example user ABC and object def doesnt exist in my database. Why I didnt get any error while creating a synonym.
Connected to Oracle Database 11g Express Edition Release 11.2.0.2.0
Connected as hr
SQL> CREATE SYNONYM test_syn FOR ABC.def;
Synonym created
SQL> Question2:
In PL/SQL after closing the cursor if we use any cursor attribute it will throw exception like invalid cursor. Why it is not happening in case of implicit cursor.
Or
Does Oracle close implicit cursor(SQL) ?
declare
begin
UPDATE emp
SET ename = 'SURI';
COMMIT;
dbms_output.put_line(SQL%rowcount);
end;Many thanks for all your help.

For example in below example user ABC and object def doesnt exist in my database. Why I didnt get any error while creating a synonym.If you look in the all_dependencies view you will see that it's created as "NON-EXISTENT", so oracle knows it's non existent, it just doesn't treat it as an error.
As it says in the documentation:
http://docs.oracle.com/cd/E11882_01/server.112/e26088/statements_7001.htm#SQLRF01401
A dependency is created and if the target object is changed or dropped etc. the synonym becomes invalid... but that doesn't mean it cannot exist.
Question2:
In PL/SQL after closing the cursor if we use any cursor attribute it will throw exception like invalid cursor. Why it is not happening in case of implicit cursor.Would you care to demonstrate what you mean with some code.

I don't want to be flippant or rude, but if people want to be professionals in ANY field, the first knowledge they need to acquire is how to locate AND USE+ the fundamental reference materials for that profession. And the most important trait, the one for which they are really hired, is the ability to do independent research, and having a modicum of curiosity that would drive one to do that research. We don't mind helping newbies, and even the most experienced person on this board will run into something they are not familiar with, or occasionally just require a second set of eyes to look at something. But a professional+ needs, above all, a willingness and capability to check the docs. A professional isn't necessarily someone who has all the answers at their fingertips or has a full understanding about every arcane subject in their field. It certainly isn't someone who has an encyclopedia full of memorized answers but little understanding of how it all fits together. It's someone who knows where to find the answers when needed, how to recognize them when he sees them. It's less about knowing than it is about attitude. Everything you asked can be answered in the Oracle Concepts Manual at tahiti.oracle.com. You should bookmark that site. You were told the name of the view that has the information you seek. It is not an unreasonable assumption that anyone who comes to this forum knows how to write simple SQL. It is also NOT unreasonable to expect a a professional to be able to take a clue like that and use it. A professional does NOT expect to be spoon-fed everything.
=================================================
Learning how to look things up in the documentation is time well spent investing in your career. To that end, you should drop everything else you are doing and do the following:
Go to tahiti.oracle.com.
Drill down to your product and version.
BOOKMARK THAT LOCATION

Do the same with the Utilities manual.
You don't have to read the above in depth. They are reference manuals. Just get familiar with what is there to be referenced. Ninety percent of the questions asked on this forum can be answered in less than 5 minutes by simply searching one of the above manuals.
Then set yourself a plan to dig deeper.
- Read a chapter a day from the Concepts Manual.
- Take a look in your alert log. One of the first things listed at startup is the initialization parms with non-default values. Read up on each one of them (listed in your alert log) in the Reference Manual.
- Take a look at your listener.ora, tnsnames.ora, and sqlnet.ora files. Go to the Network Administrators manual and read up on everything you see in those files.
- When you have finished reading the Concepts Manual, do it again.

How to find out what is populating a table

I have a table in oracle 10g, I checked the dba_source to find out if a procedure or package is population this table, however, I couldn't find it. How can I get the name of a form or other source that can populate the table. Oracle is on window Xp.
Thanks

There is nothing in Oracle that would directly tell you what can populate a particualr table. You can look at the dba|user|all_dependencies views to see if there are stored procedures that have a dependency to the table, but that does not neccessarily mean that they populate the table. Anything external to the database (e.g. an external aplpication with embedded sql statements, a sqlplus session, TOAD, etc.) would not show up anywhere in the database.

Need to get the list of all procedures called in an object

Hi,
I am trying to find the list of all proceudres called in an object. I can get the list of packages and individual procedures/functions using dba_dependencies, all_dependencies or user_dependencies. However this would not give me the list of procedures of a package that are used in my object.
How to find the procedures of a package (and not just the package name) being called in another object?
Thanks in advance
Upendra

You can take the package name from user_depencies and query the USER_SOURCE table for the object name where the package name exists.
Eg code, here PKemp is the package name.
SELECT SUBSTR(TEXT,INSTR(TEXT,'PKEMP'))
FROM USER_SOURCE
WHERE NAME = 'PROCEMP'
AND INSTR(TEXT,'PKEMP') >=1
SUBSTR(TEXT,INSTR(TEXT,'PKEMP'))
PKEMP.SALUP;

Reg: Check View/MView query -

Hi Experts,
I'm trying to search for all references of a Table (in ALL_SOURCE). But not able to check into the query of VIEWs and MVIEWs.
ALL_VIEWS and ALL_MVIEWS have LONG columns called TEXT and QUERY respectively.
Any pointers how can I search into these columns?
Help much appreciated!
Ranit B.

You can use all_dependencies
SELECT *
FROM all_dependencies
WHERE type = 'VIEW'
AND referenced_owner = 'TABLE_OWNER'
AND referenced_name = 'YOUR_TABLE';Or you can have a look at Long to Varchar2 conversion....

Hi,
Not sure if I get it, but you can look for characters using the ascii and chr functions.
You can change them using replace:
A new line:
SQL> select ascii('
2 ') from dual;
ASCII('')
 10(Just press enter between the quotes)
Example how to replace it with a space:
SQL> with t as ( -- generating test string:
2 select 'this string has
3 a new line' str from dual
4 )
5 --
6 -- actual query:
7 --
8 select str
9 , replace(str, chr(10), chr(32))
10 from t;
STR REPLACE(STR,CHR(10),CHR(32
this string has this string has a new line
a new lineIf that isn't clear of when I'm missing the point then please post some narrowes down examples of what you get now and your desired output. Remember to put the tag around any code example you're posting.

In which Oracle version is that possibile?

I've tried to create these procedure that I've found.
CREATE OR REPLACE PROCEDURE genlookup (tab IN VARCHAR2, col IN VARCHAR2)
IS
BEGIN
pl ('CREATE OR REPLACE FUNCTION ' || l_ltab || '_row_for (');
pl (' ' || l_lcol || '_in IN ' || l_ltab || '.' || l_lcol || '%TYPE)');
pl ('/');
END;
but I get a compilation error:
PLS-00201: identifier 'PL' must be declared
In which version is the PL istruction available?
I've got Oracle 8i.
My target is to write a procedure that having in Input N tables is able to autogenerate coding of a "select from where" putting in join the N tables by using ALL_DEPENDENCIES table so as to create queries automatically.
The site where I've found the above create procedure, let see that by giving after comlipation "exec genlookup" you get the CREATE OR REPLACE FUNCTION well formed, but as in my case 'pl' istrucion doesn't work, should I create one row of code a time and put it in a varrray and make dbms_out.put_line reporting the whole select or you have any smart way to do it?
Thanks!

PL (Feuerstein) en P (Kyte) procedures are usually wrappers around dbms_output, in order to save you from typing dbms_output.put_line constantly.
See:
http://asktom.oracle.com/pls/asktom/f?p=100:11:0::::P11_QUESTION_ID:1288401763279 for an example of P. Just copy ity and call it PL instead of P

How to find level of dependencies for oracle objects....

Hi,
in oracle if we have to find the dependencies we use "all_dependencies", how ever if
we have to find level of dependencies then how should we go about it,
example as shown below;
master object : tablel1
view 1:            v_test using table1
view 2:            v_test2 using v_test
view 3:            v_test3 using v_test2:
so in this case
the master table1 is having level of dependency 0
v_test is having level of dependency 1
v_test2 is having level of dependency 2
v_test3 is having level of dependency 3
and so on....
i hope i am clear in my question,
plz assist,
regards
uvEdited by: Nicloei W on Oct 7, 2008 7:53 PM

You can use a hierarchical query on the USER_/ ALL_/ DBA_DEPENDENCIES table, i.e.
select level, a.*
from dba_dependencies a
start with referenced_name = 'DEPT'
        and owner = 'SCOTT'
connect by nocycle prior owner = referenced_owner
               and prior name = referenced_name
order siblings by nameJustin

Alternative variant (and maybe more simple) - use dictionary view DBA_DEPENDENCIES (or all_dependencies):
select * from dba_dependencies where owner='MAP_OWNER' and type in ('PACKAGE','PACKAGE_BODY') and name='MAP_NAME'

Confused ... ALL_DEPENDECIES view does not contain indexes?

I try to generate a installation sequence for all my objects, for this I experimented with the all_dependecies view
1st generate a table with all objects:
<pre>
drop table rank_sources;
create table rank_sources as
select rownum as rn, object_name, object_type, owner from all_objects
where owner = 'SYS';
commit;
select * from rank_sources;
</pre>
afterwards fire a pl/sql
<pre>
set serveroutput on
declare
cursor l_cursor is select * from rank_sources for update;
l_found boolean := false;
begin
for src in l_cursor loop
l_found := false;
for dep in (
select level, referenced_name, referenced_type
from DBA_DEPENDENCIES
where owner = src.owner
and referenced_owner = src.owner
start with name = src.object_name and type = src.object_type
connect by name = prior referenced_name and type = prior referenced_type
loop
l_found := true;
update rank_sources
set rn = src.rn - dep.level
where object_name = dep.referenced_name
and object_type = dep.referenced_type;
end loop;
if not l_found then
update rank_sources
set rn = -9999999999 where CURRENT OF l_cursor;
end if;
end loop;
commit;
end;
</pre>
As you can see, there are potentially indexes with a lower rank than their table. When you do a
<pre>select * from all_dependencies where type like '%INDEX%'</pre>
the result is NULL - I am really confused why indexes are not referencing to their tables?? So in case of Index I have to query seperatly all_indexes.
But when you look at the all_dependecies view definition you can see, index as an expected type - is this a bug? I use Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production
<pre>
SET DEFINE OFF;
DROP VIEW SYS.ALL_DEPENDENCIES
/* Formatted on 20.10.2010 12:31:15 (QP5 v5.149.1003.31008) */
CREATE OR REPLACE FORCE VIEW SYS.ALL_DEPENDENCIES
OWNER,
NAME,
TYPE,
REFERENCED_OWNER,
REFERENCED_NAME,
REFERENCED_TYPE,
REFERENCED_LINK_NAME,
DEPENDENCY_TYPE
AS
SELECT u.name,
o.name,
DECODE (o.type#,
0, 'NEXT OBJECT',
1, 'INDEX',
2, 'TABLE',
3, 'CLUSTER',
4, 'VIEW',
</pre>
Thanks

Ok, so what I have done so far - to get a solution for my requirement - I created a sys view like this:
<pre>
create or replace
view REALLY_ALL_DEPENDENCIES as
select *
from ALL_DEPENDENCIES
union
select owner, index_name, 'INDEX', table_owner, table_name, table_type, null, null
from all_indexes
union
select p.owner, p.table_name, 'TABLE', f.owner, f.table_name, 'TABLE', null, null
from all_constraints p
join all_constraints f
on F.R_CONSTRAINT_NAME = P.CONSTRAINT_NAME
and F.CONSTRAINT_TYPE = 'R'
and p.constraint_type='P'
</pre>
Since union is checking for duplicates, it should be harmless to use this view from now on :-) ... ok, performance is not really good, but I do not use the view every minute - maybe once a day.
Thanks and cheers
