Changing schema names

Is there a way of changing the name of a schema?? I know in dba studio you can only change the password. Thanks.
TP

The only way to change the schema name is to export then import.
Basically, the steps are
1. Export old_user schema
2. Drop old_user cascade
3. Create new_user
4. Import fromuser=old_user touser=new_user
null

How to programatically change schema name for an application ? JDev10g

I am using JDeveloper 10g 10.1.3.4
What I am trying to do is: while connecting to the database instace with login/passwd credentials for a specific schema, being able to take in
schema as a separate paramter and connect to that schema.
Connecting to a database instace ORCL to the hr schema say with hr/hr
supply a paramter schema_name: scott. and connect to the scott schema as the hr schema user.
In SQL Plus* all you do is
connect as hr/hr
and then
alter session set current_schema = scott.
While developing an application that autheticates against database username/pwd credentials I was using the methodology
as described on http://www.oracle.com/technology/products/jdev/howtos/10g/dynamicjdbchowto.html
and http://radio.weblogs.com/0118231/stories/2004/09/23/notYetDocumentedAdfSampleApplications.htmlexample 14.*[Dynamic JDBC Credentials for Model 1 and Model 2|http://otn.oracle.com/products/jdev/tips/muench/dynamiccredentials/DynamicCredentials1013.zip]* [10.1.3.3] 2006, Upd: 17-MAY-2007 by Steve Muench
In the DynamicJDBCBindingFilter that in the doFilter() method, I was trying to find a way to be able to specify the schema name
as in sessoion.setAttribute(Configuration.<SomeProperty>, schema);
is there any property/parameter that can be set to change the schema within the context of the application?
because in all the code that i see there are attributes of 'Configuration' that are being set.
So I don't think there is way for me to just write straight up jdbc code to
create a connection and run the statement "alter session set current_schema = scott"
and be able to pass the login credentials
and connect to the schema I want to.
Any help would be appreciated.

Hi,
I am not sure if JDBC really supports this. I found
JDBC alter session set ...
but this never got a success/failure statement.
If you want to use a singe connection but different schema for users then you may want to have a look at proxy user authentication, which is exatly doing what you want - use a single user to get into the database and then have him mapped to his own schema to work in

Change schema name without doing export and import

Is there a way of changing the name of a database schema without having to create a new user and exportng objects from the old schema into the new schema?
Are there any system tables that can be changed to modify schema name without creating a new schema?

4.1 EA2 Migration from SQLServer: can't change schema name?

I try to convert a SQL Server database to Oracle.
As I wanted to insert into an existing schema (with not the same name as on SQL Server) I followed this guideline:
A SQL Developer ... @dermotoneill: Migrate to Existing Oracle Users
I first captured the source and then tried to Convert the naming.
but the tab does not exist:
(you can see it really is showing pre-captured data as I can select the "Show only data types used in source model" checkbox)
Is there a new way now how to map the schema?
thank you,
Martin

Hi Martin,
That object naming page has been removed from the migration wizard.
The functionality is now available in the object migration report.
Its easier to work with the report as you can filter and order the objects based on your requirements.
In this case you can just show the OBJECT_TYPE='SCHEMA'.
So the steps are.
1) Capture and Convert you source database
2) Open the Object report (left click on the "Converted Database Objects" node) and change the SCHEMA objects TARGET_OBJECT_NAME to your desired target name. Commit changes.
3) Translate and Generate the Oracle database (right click on the "Converted Database Objects" node)

Change schema runtime in procedure

Hello friends,
I have one query in procedure. I have same table with same structure and name in more than 10 schema. I want to access these table records dynamically using procedure.
I want to change schema name in procedure.
Please check below PL/SQL code i have wrote.
declare
     cursor c1 IS
     select deptno,dname,loc from &schema..dept;
begin
     for rec in c1
     loop
          dbms_output.put_line(rec.deptno || ' ' || rec.dname || ' ' || rec.loc);
     end loop;
end;
I want same functionality using procedure. Please check procedure code below:
create or replace procedure diff_schema (schema_name IN varchar2)
Declare
     cursor c1 IS
     select deptno,dname,loc from schema_name.dept;
AS
begin
     for rec in c1
     loop
          dbms_output.put_line(rec.deptno || ' ' || rec.dname || ' ' || rec.loc);
     end loop;
end;
but it returns error.
Please help me to solve this issue.

That still assumes that the emp table exists in the schema in which the procedure is compiled because you have:
v_all emp%rowtype;Essentially what the OP is asking for indicates that whereve the procedure is defined is going to need to know the structure of the tables it's going to use otherwise everything about it would need to be dynamic.
We have a process on one of our databases that has a similar setup, where there are several schema's all containing the same table structure, but different data, and we need a central setup of code that can process each of those as required.
For us we looked at it from a different perspective. Rather than having the central procedure try and access all the other schemas, for which it would need to know which schemas it has to access etc. and because sometimes some of those schemas should be excluded from the process if they have had an issue with their data being populated (it's a regular job to repopulate them and determine changes on them etc. - a bit of an ETL task really), we leave it up to the individual schemas to determine when the processing is necessary (i.e. when they each know their own data is ready to be processed). The advantage of that is that the central procedure's those schemas use all use the AUTHID CURRENT_USER, so the central schema just has a blank copy of the tables so the code can compile, but when the other schemas call the procedure, they are running the code against their own tables because of the AUTHID setting. It avoids any dynamic coding, or any (mis/ab)use of ref cursors, and it gives the flexibility that each schema is in control of it's own destiny, and other schemas can be added or removed as necessary without having to have some central control mechanism to know which schemas need processing.Thank you Blu,i'm learning lot of things from you...you are a champion

Is it possible to change schema or name of locally built provider in portal

Is it possible to change schema or name of locally built provider in portal 9.0.4?
We have built an application as a pagegroup and locally built provider in Oracle portal. We can deploy the application to different portals using transport sets. However, it is not possible to install the same provider twice to a shared portal because a provider's name and schema cannot be changed. Does anyone know of a way to rename and change the schema of locally built providers? I was once told that substition strings at import would be available in an upcoming release to do that, but I haven't seen anything like that.
Thanks,

Change Logical Schema name of an existing interface

How do we change the logical schema name of an existing interface which is pointing to a different logical schema. Note: Both two different logical schema are pointing to the same database schema.
Thanks in advance for your update.
Kaustuv

I'm not sure it's good to have two different logical schemas pointing to the same physical schema.
Whatever, what do you want to change ?
The logical schema of a source datastore ? Of a target datastore? Of a target temporary interface? Or the staging area ?

I need to change the name of Schema in the Insert command by using variable

Hi
I need to write a code to populate 450 schemas having same table names and also specify the columns needed to be inserted. for that i am trying to make the Schema Name a variable and put the whole statement in a loop to change the name of the Schema. its not working can any one guide me in this..Thae sample of my insert statement is
INSERT INTO A01.tablename
In this the "A" is constant and 01 is being changed to 02...450..

Not sure to completely understand your need, but assuming that column names and values to be inserted are the same for all schemas, here a short example :

How to parameterize the schema name in APEX

Hi,
How to parameterize the schema name in APEX , in order to access different tables from the respective schema.
For example:-
select NAME display_value, CODE return_value
from paramSchema.DESC_LIST WHERE SELECTION_FLG = 'Y'
order by 1
in the above code, paramSchema will be replaced with the actual schema name duing runtime. I tried doing so by some hidden fields on page, but it didn't worked out.
I took the schema name from the respective server as per the IPof the server.
stored in a hidden field named as schema.
And replaced the same in place of schema name. But no luck.
select NAME display_value, CODE return_value
from :schema.DESC_LIST WHERE SELECTION_FLG = 'Y'
order by 1
Please help me in shorting it out.
Thanks,
Anuradha

Hi
In order to do that, you would need to use dynamic SQL by changing the report type to PL/SQL Function Body Returning SQL Query and have code along the lines of
DECLARE
l_sql VARCHAR2(32767);
BEGIN
l_sql := 'select NAME display_value, CODE return_value
from '||:schema||'.DESC_LIST WHERE SELECTION_FLG = 'Y'
order by 1';
RETURN l_sql;
END;However, by doing this, you lose alot of flexibility. The other options would be...
To have seperate report regions that are conditional on the value of the variable.
To use a WITH clause at the tope of the query like...
WITH src_data AS
(SELECT * FROM schema1.my_table
WHERE :schema = 'schema1'
UNION ALL
SELECT * FROM schema2.my_table
WHERE :schema = 'schema2')
SELECT *
FROM src_dataOther than that you could look at using synonyms and doing something similar.
Hope this helps.
Cheers
Ben

Need to know schema name and table name associated with a column-URGENT

Hi folks,
I need to know the schema name and the table name associated with a column. Though jdbc has the api to getTableName and getSchemaName, some database vendor like oracle does return empty upon call of mentioned methods. I found that oracle driver does not support that
Can any one give me the solution? It is urgent. Or do you suggest any third pary jdbc driver which can provide those?
Thanks
Angelina

Angelina,
Your question has been discussed several times previously in this forum. Search this forum's archives for "getTableName". Oracle JDBC driver does not implement this (because "it is not feasible" -- according to Oracle).
First of all, I would suggest that you could probably change your application's logic so that you would not need this functionality (but I guess that is not feasible either, right :-)
Alternatively, you could try querying the Oracle database data dictionary.
Good Luck,
Avi.

Default schema names in multi-tier landscape

Hi folks,
We have an interesting problem due to having different named default schemas in each of our 3 hana systems. For example lets say these are our default schemas in our development, staging, and production HANA systems;
DEV_SCHEMA
QA_SCHEMA
PROD_SCHEMA
Each of these replicating data from their corresponding SAP source systems.
Now, we have a view that is developed on DEV hana box and uses DEV_SCHEMA. When this view content is imported to QA or PROD we handle easily with schema mapping. All is well and good although we are not really a fan of this different naming and us developers did not choose this naming (self defense plea here for us brilliant developers whom never make such mistakes... PS: HI LARS! - Go Germany!)
Now we are setting up a connection from BW into HANA using system connection and inside this is a parameter called 'db user'. Although it's called db user it's actually looking for a SCHEMA name. If BW DEV is querying from HANA DEV this schema name would be DEV_SCHEMA. However if BW_QA is querying from HANA_QA then the name would need to be QA_SCHEMA but in our BW landscape we are locked in QA and PROD and normally can not and/or do not want to edit objects in non-native systems. Ideally what we need is our default schemas in HANA to have the same exact name throughout the HANA landscape.
All this said, I can see that it would be great to re-name our entire HANA landscape however that would be a HUGE monumental undertaking as all systems would need to be re-replicated again (at least I think).
Just curious if anybody else has named their schemas differently on each tier? What are most people doing? Naming the default schemas the same consistently or are you using schema mapping?
Thanks,
-Patrick

Hi Luke,
I am new to the project and there seems to be no original version. At some point a bunch of the destination field names were changed on the admin console and errors resulted from it both due to mismatched joins and the use of two word field names. I have documentation of the names for the set of tables in the function area but am having trouble with how everything matches up in the bottom half.. I'll keep working on it

Schema name in DB Adapter

Hi,
Schema name is hardcoded in the DB adpater even if I am not selecting the schema name while creation.
<jca:operation
SchemaName="APPS"
PackageName="XX_PKG"
ProcedureName="POPULATE_DATA"
InteractionSpec="oracle.tip.adapter.db.DBStoredProcedureInteractionSpec" >
How do I make it generic? Can I remove SchemaName parameter?
My JNDI Url may change dynamically and the target database may have different schemas.
Thanks,
Rishi

The adapter uses the schema name to qualify the stored procedure invocation (e.g. "APPS.XX_PKG.POPULATE_DATA"). Having the schema name means that you can invoke a stored procedure in a schema other than the one associated with your connection. If you remove the schema name then the qualified execution will be "XX_PKG.POPULATE_DATA" and the schema will be your connection schema. So be careful about removing the schema name because the stored procedure qualified by package name alone may not be enough to resolve it for execution. In other words, the package containing your stored procedure may not exist in the schema associated with your connection.
