Reporting on Data Dictionary Views

We are in the process of documenting our database, and it seems like there should be an easy way of doing so, given all the information provided in the data dictionary views. I haven't used Oracle Reports yet, and I was wondering if it will create reports based on these tables/views. I tried Crystal, and it does not see these views. I assume I could write a SQL statement with formatting to create a text report, but I would rather use the Reports tool. Will this work? Is there another tool/better way to document the relationships, constraints, etc., etc., of the database?

Oracle Designer - This is the best tool to use for your requirements. impact analysis reports, db design, reverse engineering and uml modelling etc... all in one tool.

Can we determine path of my INIT.ORA file from data dictionary views.

Hello Guru’s
I am new to oracle, My question is for the sake of my knowledge: I work on oracle 10G.
Is there any data dictionary view from where I can get the path of my INIT.ORA file.

AFAIK , its no. You can check the path from the show parameter command like following,

Result_cache and data dictionary views

Hi,
Are there any special considerations when caching the results of a function which uses data dictionary views to determine it's results?
This question has popped because I have a such a result_cached function for which the result_cache objects are not getting invalidated even when the underlying data dictionary views have changed and the function gives 'stale' values in it's output. Adding the relies_on clause has not helped either.
Here is what I am trying to do:
The function accepts table name as its input and tries to determine all the child tables using the sys.dba_constraints view. The results are returned in a pl/sql table and are cached so that the subsequent calls to this function use the result_cache.
Everything works fine for the parent/child tables which have been created before the creation of this function. All the results are correct.
The problem starts when a new child table is added to an existing parent table.
The v$result_cache_objects view shows the result of this function as 'Published' and the output of the function does not show the newly created child table.
Same is the case when an existing child table is deleted; the function continues to return it in the output as it is pulled from the result_cache.
Oracle version:
Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production
PL/SQL Release 11.2.0.1.0 - Production
CORE 11.2.0.1.0 Production
TNS for Linux: Version 11.2.0.1.0 - Production
NLSRTL Version 11.2.0.1.0 - Production

>
Restrictions on Result-Cached Functions*
To be result-cached, a function must meet all of these criteria:
* It is not defined in a module that has invoker's rights or in an anonymous block.
* It is not a pipelined table function.
* It does not reference dictionary tables, temporary tables, sequences, or nondeterministic SQL functions.
For more information, see Oracle Database Performance Tuning Guide.
* It has no OUT or IN OUT parameters.
* No IN parameter has one of these types:
o BLOB
o CLOB
o NCLOB
o REF CURSOR
o Collection
o Object
o Record
* The return type is none of these:
o BLOB
o CLOB
o NCLOB
o REF CURSOR
o Object
o Record or PL/SQL collection that contains an unsupported return type
It is recommended that a result-cached function also meet these criteria:
* It has no side effects.
For information about side effects, see "Subprogram Side Effects".
* It does not depend on session-specific settings.
For more information, see "Making Result-Cached Functions Handle Session-Specific Settings".
* It does not depend on session-specific application contexts.

Data Dictionary View for Procedure Text

Hi,
Is there a data-dictionary where I can see the body of procedures. In fact, I received a request from a collegue to give him the procedure name which access a table "table_1".
So, my idea is to write a query as follows:
SELECT <procedure_name> FROM <data_dictionary> WHERE <text> LIKE '%table_1%'.
Thanks in advance.

You can try with DBA_SOURCE or USER_SOURCE.
i.e.
SELECT NAME FROM DBA_SOURCE
WHERE OWNER='<OWNER NAME>'
AND TYPE='PROCEDURE'
AND TEXT LIKE '%table_1%';

Can not select from data dictionary view from a procedure

Hi,
I wonder, which privilege is missing here:
my schema has this roles and privs:
GRANT CONNECT, RESOURCE TO cb ;
GRANT CREATE SESSION TO cb ;
GRANT SELECT_CATALOG_ROLE TO cb ;
GRANT CREATE SYNONYM TO CB;
GRANT CREATE VIEW TO CB;
I create a procedure:
create or replace procedure dd_test as
begin
     dbms_output.enable(2000000);
     for r in (select table_name from sys.dba_tab_partitions     where owner = 'CB') loop
               dbms_output.put_line(r.table_name);
     end loop;
end;
sho err
4/38 PL/SQL: ORA-00942: table or view does not exist
When I run the core statement form sql prompt, it works !
so what privilege is missing here ???
thanks for any hint, Lao De

Hi,
thanks for that reply, after doing that I can not select this DD-view from sql-prompt anymore (which I don't wonder ;-). Can you tell me, what idea you had behind that test ?
I found another instance, where the procedure works and I will compare those privileges, but it's hard to sort out that complex structure of nested roles and sys_privs.
How ever, I will update here, when I found the missing privilege.

Query to obtain tables in SH schema using data-dictionary views/tables.

Hi,
I have just installed Oracle 10g Database. Logged on to SQL Plus by scott (changed the password as prompted).
I want to see the tables in SH schema (which comes by default with Oracle 10g database).
The problem, I am facing is:
I can see the schema name: SH in the result of the below query:
SELECT * FROM ALL_USERS
but, nothing is returned in the result of the below query:
SQL> SELECT OWNER FROM ALL_TABLES WHERE OWNER='SH';
Result: no rows selected.
Why is this happening?
What will be the correct query to obtain tables present in SH schema ?
Thanks in Advance & Regards,
Deeba

conn /as sysdba
SQL> select table_name from dba_tables where owner='SH';
I think the user SCOTT have no privilege to see SH schema tables through all_tables view.
Thanks

How to do outer join in data model view?

Hi,
I have 2 queries are needed to be joined in Oracle Report 6i Data Model View. What I want to do is below:
where table1.receipt_no(+)=table2.receipt_no
How do I use the 'Data Link' to do this in Data Model view?
Thanks.

Hi
You need to use data links. Refer data link section in BUilding Reports manual at http://otn.oracle.com/products/reports/htdocs/getstart/docs/B10310_01/orbr_concepts1.htm#1013156.

Data Dictionary.. Help Please

I have to create this query for my college course. I need help. I have half of the query, I think. Need another join clause in the from statement for the views, not sure what to do. Any help will be appreciated! Thank you!
Create and execute a single query of the Oracle data dictionary to display all foreign key constraints in the HR schema. Note that foreign key constraints are constraint type 'R'. For each constraint list the constraint type, constraint name, the referencing table name, the referencing column position(s), the referencing column name(s), the referenced constraint name (i.e. the other table's primary key constraint name), the referenced table, and the referenced column(s). Sort your results by constraint name, table_name, and position.
HINTS: You will need two different data dictionary views for this query. One of the views will need to be mentioned twice in the FROM clause, and therefore you will need two different aliases. With this arrangement you will also need two join conditions.
This is what i have so far...
SELECT uc.constraint_type, uc.constraint_name, uc.table_name, r_constraint_name,
ucc.table_name, ucc.position, ucc.column_name, ucc.constraint_name
FROM user_constraints uc JOIN user_cons_columns ucc
ON uc.table_name= ucc.table_name
AND uc.constraint_name= ucc.constraint_name
WHERE constraint_type= 'R'
AND r_constraint_name IN
(SELECT constraint_name
FROM all_constraints
WHERE constraint_type
IN ('P','U')
AND table_name= 'hr')
ORDER BY uc.constraint_name, ucc.table_name,ucc.position;

Ok, you have the correct two dictionary views (assuming you are logged in as HR), now you need to figure out which one is needed twice. As a hint, you have the required join columns for the doubled dictionary view in the single use dictionary view.
A couple of comments on the code you have posted so far.
The predicate:
r_constraint_name IN (SELECT constraint_name
                      FROM all_constraints
                      WHERE constraint_type IN ('P','U') AND
                            table_name= 'hr')is unnecessary since by definition, if the constraint type is R, then the r_constraint_column will point to a P (primary key) or U (unique key) constraint.
By default, all objects in Oracle are stored in the dictionary views in upper case, so when you query a value you need to use upper case for the literal.
Again, assuming that you are logged in as HR, then the user_xxx views will only show objects that belong to the HR schema, so there is no need to qualify anything with an owner.
When you are posting code on this site type {noformat}{noformat} before and after your code sample, this will preserve the formatting of your code so it will be more readable. If you want to see an example of this, click reply to this post and then click the quote button in the reply pane and you will see how I kept the formatting in the snippet above.

Role for system data dictionary read-only access

[NOTE: this is for 9i]
What grants must a role have to have read-only access to
the system data dictionary tables (e.g.: ALL_SOURCE,
ALL_OBJECTS, ...)?
Or, is there somewhere in the docs that talks about this
kind of role?
Thanks in advance,
Robert

Well, the answer to your explicit question would be that it would need SELECT on each of the data dictionary views that do not have SELECT granted to PUBLIC. To find out what those are, you could do:
SELECT table_name, privilege
FROM dba_tab_privs
WHERE grantee = 'SELECT_CATALOG_ROLE'however, it would probably be easier just to grant it SELECT_CATALOG_ROLE :-)

Table or view does not exist - Data Dictionary Import Wizard(Data Modeler)

Hi All,
In Data Modeler, Data Dictionary Import Wizard, I'm able to connect to database.But while going to the second stage (Select Schema/Database), I'm getting an error "ORA-00942: table or view does not exist".
I am able to select the table with select * from all_tables and I can open many tables as well.
Could anyone tell me, whether I'm missing any privilege, that causing this error.
Thanks in advance for you support.
Thanks.

New To SQL Developer Data Modeler - Data Dictionary Report

I am new to Data Modeler and I am currently learning what I can do and can't with it. Is there a way to generate a "Data Dictionary" report? We would like a report we can distribute that describes all tables and columns with descriptions and comments. We used to use an old version of Power Designer and we could do this from the data model we created. Is it possible to do something like this from SQL Developer Datas Modeler?

Hi,
Saxon is just an option, you don't need it by default.
Could be permissions problem. What are you working on i.e. OS? What java version do you use?
Even though you have specified directory for the reports do you have permissions to write there?
Report generation directories priority is:
1. Custom directory if specified in Settings->Data Modeler->Default Reports Directory
2. /datamodeler/reports/
3. User home directory
You must have permissions somewhere on these directories. On the other hand you are saying that report_data.xml is generated so you have permissions.
Okay. Now I saw a bug in 710. When you click "Generate report" there are progress dialogs and result dialog, but if you meanwhile click somewhere or change focus, these dialogs are hiding below main "Reports" dialog i.e. you are not seeing them. If you use Alt+Tab the result dialog will popup. This bug is fixed in the next release.
So you must see either result dialog or error dialog at the end of report generation. If not check with Alt+Tab if it is not hidden somewhere below and if there is no such dialog close the DataModeler and check the log file for some error.
There is SQL Developer Data Modeler 3.3 Early Adopter Available.
http://www.oracle.com/technetwork/developer-tools/datamodeler/downloads/datamodeler-33-ea-1869055.html
Above issue is fixed there and report is opening automatically.
