How to create clustered index in Oracle ?

I need to Create unique clustered index idx_col1 on table1(col1) in Oracle 9i.
Should I declare it at creation of table as index-organized ? My table is created with the code like Create table table1 as select ..... from ....
Can anybody post an example ?
Thanks

Oracle does not have the concept of a clustered index from SQL Server. You may get something similar if you create your table as an index organized table, i.e.
CREATE TABLE my_iot (
  col1 number primary key,
  col2 number
organization index;or you may get similar benefits by creating a cluster. It really depends on what functionality you're trying to replicate and what problem your trying to solve. Either way, though, you'll have to have separate steps to create the table and then to insert the data.

  • How to create clustered index?

    When working with Relational model I do not see how to make index clustered? All indexes (as well as primary keys) are created non clustered so far...

    In an Oracle Physical Model, you can create a Cluster and create an Index on that ClusterI am designing for SQL Server, not for Oracle. So Oracle specific approaches would not help me.
    Even for the Oracle (which I do not know much but I can guess) I think that this is not what I was asking for. I simply need to create a clustered index, not to include column into some cluster. In other words I need that generated DDL looks like
    create clustered index...
    Now it always looks like
    create nonclustered index...

  • How do I set access 2002 Upsizing Wizard to create clustered-index on SQL 2005

    Here is an extract from the Acc2Sql2.doc  >>
    By default, the Upsizing Wizard
    transfers all indexes as nonclustered indexes. You can modify the Upsizing
    Wizard to transfer the primary key index to a clustered index. To make this
    change, start Microsoft Access and open the upsizing wizard library database.
    For Microsoft Access 95, the filename is Wzcs.mda. For Microsoft Access 97, the
    filename is Wzcs97.mda. When the database is open, click the Modules tab and open the
    UT_ModUserConstants module. Search down to the UT_CLUSTERED constant. Change
    the default value from False to True.
    <<< end quote
    Question: I am using ACCESS 2002 upsize wizard, I searched my computer for *.mda and could not find any wzcs*.mda.  How do I set it so that it creates clustered-index instead of non-clustered-index?

    Hi,
    This question is not related to the forum. This is a question regarding MS-ACCESS.

    how to create a user in oracle level.i know how to create from front end.can any body suggest.how to create oracle user from backend.
    Thanks,
    Dave

    Hi,
    We can use the 'hr_user_acct_internal.create_fnd_user' API to create the users. The sample code is as follows:
    BEGIN
    apps.hr_user_acct_internal.create_fnd_user
    (p_user_name => 'XXX',
    p_password => 'XXX',
    p_employee_id => 1234(This is the person id from per_all_people_f),
    p_user_id => x_user_id,
    p_user_start_date => SYSDATE,
    p_email_address => 'XXX',
    p_description => 'XXX',
    p_password_date => NULL
    COMMIT;
    END;
    and to add the responsibility to the user, we can use the following code.
    BEGIN
    fnd_user_pkg.addresp
    (username => 'XXX',
    resp_app => user_res_rec.application_short_name,
    resp_key => user_res_rec.responsibility_key,
    security_group => 'STANDARD',
    description => 'DESCRIPTION',
    start_date => SYSDATE,
    end_date => NULL
    END

  • How to create a Index for KM documents

    Hi Experts.......
    I have two queries .
    1,How to create a Index for the KM Server documents so that when ever i am in need of particular document,i can be able to retrive the exact document within short time......
    2,What Is TREX? Need of TREX ?
    If any one have documents for the above said queries kindly send it to [email protected]
    Thanks in Advance,
    Jasmine

    Hi Jasmine,
    1.In the EP 6.0 you can create index System Administration -> System Configuration -> Knowledge Management -> Index Administration
    2.TREX is search engine that will proccess the documents that you have specified in the index Data sources when you have created the index.
    The status of TREX you can see in System Administration -> Monitoring -> Knowledge Management -> TREX Monitor or Index Monitor for indexing monitoring.
    If you don't have connected any TREX engine to J2EE, just start the visual administrator and configure the TREX service.
    To install the TREX you can follow the instguides for TREX service.sap.com/instguides SAP Netweaver->Release 04 or 2004s -> Installation -> Cross-NW
    I hope that it helps.
    Bye

  • How to create new database on Oracle 10g

    Hi All,
    Can any one tell me how to create new database on oracle 10g.
    Thanks in Advance for your help.

    again some confusion here.....
    u said u need a new database in your first post and now you saying u need a new schema..
    one database has many schemas(users)..... ex: scott,sys,system are few of them...
    now it depends you need seperate database for test,dev environment - this is in the case u have many schemas under each database and many tables(objects) under each schema.
    OR
    You just need a separate schema (in same db) for test,dev environment...where in you will have multiple tables in each schema...U need to know the dba credentials of the db to create a new schema.
    ideally u need to have different database...You can create one with out sys/system(oracle users) password as these passwords are db dependent.
    what you need is access to the any machine where server is installed(can be the same mc where you have your dev db or a diff machine) and that will be the machine where your db will be installed (can do it through database configuration assistance),ofcourse you will need windows authentication for this.
    so you login to the same machine or access it from your machine using remote login.
    I hope that is clear.Hope i am not listing things that you already know..Just did it coz of confusion between db and schema
