Exporting views from a schema

Hi Gurus,
We have a problem while creating a replica of a remote DB in local.
We were able to export all DB objects except views.
As they are critical for making the local DB 'complete', we are looking for a solution.
We have tried the below query for getting the definition for a single view on a schema, but the query is taking too much time, even if run on the server.
Select dbms_metadata.get_ddl('VIEW','<VIEW NAME>') from dual
Please suggeest us a solution for the same.
NOTE: Unfortunately we don't have any advanced tools and we are just relying on the Oracle SQL developer, even for developement.
Thanks & Regards
RK Veluvali

What error are you getting when you run datapump expdp? If all you want it views you could run
expdp user/password include=views schema=schema_list ...
Please post the version you are using and the errors.
Thanks

Renaming View from another schema

Hi,
I've 2 schemas namely department , hr
Now department schema is having one table EMP . And a view is created on that table with the name R_EMP
Schema Name : department
Table Name : EMP
View Name : R_EMP
GRANT SELECT ON R_EMP TO HR ;
In HR schema a synonym has been created on view R_EMP with the name R_EMP .
CREATE OR REPLACE SYNONYM hr.R_EMP for department.R_EMP
Schema Name : hr
Synonym Name: R_EMP
Now I want to rename the view name R_EMP to V_EMP from HR schema only
So, I tried the folloiwng syntax in HR schema (All the operations should be done from this schema only )
[code]
RENAME department.R_EMP to department.V_EMP ;
Error:
ORA-01765: specifying table's owner name is not allowed
[/code]
How to change the syntax to make the statement work from HR schema .
Thank You .

How to rename a table in another user's schema
You can alter the session to set your current schema to the name of the schema where you want to rename the view and then do a direct rename.

Error using views from other schema

Hello,
i recently had problems using the execute immediate statement in Object Types.
The SQL statement tried to select from some views which were owned by an other schema.
Although we had public synonyms on these views and the same dynamic sql could be used out of a stored procedure the usage in the object type raised a "table or view does not exist exception".
using the same views in the same schema where the object types belonged to, was ok.
example:
schema: scott
view: my_view
schema: dave
sql: "select from scott.my.view ....."
works well from a stored procedure, but nor if used in an object type
create the view in schema "dave" an then
sql: "select from my.view ....."
works fine.
So is someone aware of this behaviour?
Is this a bug or a feature?
regards
peter

Hello Geoff,
here is the sample code.
If the table my_table belongs to the same
schema runningthe code the code runs with
no exception.
But if the table belongs to an other schema
(lets say SCOTT),
only having global synonyms and the rigths to
select on it, the code will raise an exception "table or view does not exist"
even if we use SCOTT.my_table in the
select.
create type query_o as object(
dummy integer,
static function get_query return
varchar2;
create or replace type body query_o as
static function get_query return varchar2
as
query varchar2(4000) :=
'select ' | |
' f.amount_month ' | |
'into :r1 ' | |
'from ' | |
' my_table f ' | |
'where id=:p1 ';
begin
return query;
end;
end;
create type consumer_o as object(
amount_month number,
member function find(p_id in integer)
return consumer_o
create type body consumer_o as
member function find(p_id in integer)
return consumer_o
as
l_amount number;
begin
execute immediate query_o.get_query()
using out l_amount,
in p_id;
return consumer_o( l_amount );
end;
end;
kind regards

Export data from one schema to another schema through sql

Hello.
I have 2 schemes. One is called MICC_ADMIN and the other one is called MICC_PROD. What I want is to export from MICC_ADMIN to import in MICC_PROD. I tried to do it with the Data Workshop tool, but one of the table has around 19.000 records, so it gets frozen when is trying to export the data. So I'm wondering if is there any way to do it through sql command. Thanks.
Regards, Bernardo.

I am going to assume that you:
1) want to export DB objects from the source schema (MICC_ADMIN) to your target schema (MICC_PROD)
2) awant to export the data held in the aforementioned tables between the two schemas
Firstly, generate the relevant DDL for your DB objects (you can do this in APEX as well - Home>Utilities>Generate DDL then complete the wizard) and run the DDL script in your target schema.
Secondly, grant access to the relevant tables in the source schema to your target schema and compose DML insert statements to transfer the data from one to another (remembering to disable the relevant constraints/triggers during the process).
Thereafter, revoke access to your source schema.
You can, of course execute this in a single script, although better to do so in a test environment first if you can!

Can't see DDL of views from other schemas in Developer?

Hi,
I've seen elements of this problem in other threads but this problem of course has it's own twist.
I can see other schema's objects EXCEPT VIEW DDL.
I have given a user every role and priv that I can and they still can't see the view ddl of another schema. They can see procedures, functions etc. just not the view. I've found that if I use the user that created the users I can see the DDL of all subordinate users. Users created under that schema can not see each others views no matter what rights are given. Interestingly enough sometimes when I look to display view DDL it will flash the DDL briefly before blanking the screen. very frustrating. All the Toad fanboys are crowing about how they couldn't possibly use a tool that doesn't allow them to see other view source.
I have also looked for settings in the preferences but could find none.
Is this a bug? It seems like one to me.
Any help is greatly appreciated.
Thanks
Mark

Import from other schemas other than default

Hi,
I defined a source metadata location to an Oracle database. The user used to connect to the DB itself has no objects. I need to import tables and views from other schemas in the source Oracle database. It that possible using the same user that was used in creating the metadata source location? Or, does one need specific one-to-one connection established as separate source metadata locations in order to import tables and views from other schemas?
In other words, is one user/password to a database sufficient to import tables and views from other schemas?
Thanks!

I'm not sure you can import directly into the Android version of Firefox due to security limitation on the device. If you can get your Opera bookmarks into Firefox on the desktop, you can use Firefox Sync to move them to your mobile.

Export views and business areas from dev to prod.

Hi Gurus,
I am using oracle database 10gR2 and Oracle BI Discoverer Administration 10gR2.
I have an End User Layer disadmin1 with 10 business areas. This EUL also have folders for the views in its own schema. I used original import/export utility to export this EUL from Development to Production environment.I exported the schema disadmin1 form development and imported it into production into same shcema disadmin1 (This exported the views too) . It is absolutely working fine.
Now I have to develop 5 more business areas in the same EUL as phase 2 development I am keeping the EUL disadmin1 for bug fixing for initial 10 BAs, and I have another EUL disadmin2 to develop new business areas. For these new business areas, I have to firrst create views and then create folders on these views in disadmin2. I will export the new business areas form discoverer utility 'Selected Business Areas' from disadmin2 and will import them into production in original EUL disadmin1. My problem is how can I export new views from development to production.
Thanks for the help.

With Discoverer, there is not necessarily one right way to do things. There is certainly nothing wrong with the process you are doing. I believe Oracle had a different process in mind with Oracle, but that does not mean your process is wrong. Did you install the seeded (Oracle term) business areas that come with Discoverer, and activated the business views for those Oracle business areas? Put those into Production and your users can develop workbooks on the fly in Production, rather than wait for something to go through a development-test-production process. Which can be good or bad depending on your individual situation. As for creating new views, I suggest talking to your Oracle technical team to see what process they have for approving new views in production and getting those views created. I would suggest getting those approved and created first before relying on using them for Discoverer development (just in case the creation is not approved), but that is just my opinion.

Not able to export web analysis report to excel smart view from workspace

Not able to export web analysis report to excel smart view from workspace.
Error :Web launch operation has been cancelled.
Can anyone help me to resolve this issues

I realized that I can put a block in WebI and then I can pull that in excel alongside of static header, after putting the question.
My interest to know whether it is by design in XI 3.0 or it is an issue. But by the replies it seems to me like it is by design.
@Anis: I can't go for header as part of Body. Because this report is viewed in Web by many other users. I can't have separate report for Live office, it is a restriction for me. If I use the header in body, it wont look good I guess.

I don't know what database system you use, but in the most I know it is done that way:
SELECT
A.COL1,A.COL2.....
FROM
SCHEMA_NAME.TABLENAME A,
SCHEMA_NAME.TABLE_NAME B
WHERE
A.COL1 = B.COL2
...
