Hello Gurus,
I want to create Bit map index on primary key column of a table.Is it possible? and i am getting an error ora-00439.
e.g.
create table empdtls( emp_id number primary key,
emp_name varchar2(200));
create bitmap index b_ind on empdtls(emp_id);
I want to know is the right way to create bitmap index or not.
Regards:
Sunil Madnani

You don't want to do that. A primary key is a VERY poor candidate for a Bitmap index. Think of a different way. (I would also suggest that you read and understand the documentation before attempting to implement a feature that you have little knowledge of).
In addition, a simple and very quick google would have given you:
Quote:ORA-00439: feature not enabled: string
Cause: The specified feature is not enabled.
Action: Do not attempt to use this feature.
I would say that this is pretty obvious.

Once again we have a an error message but not text. I have no desire to look the error up.
Why did you take the time to write a post to us, give us an error number, but then not take the time to give us the text of the message?
One of my peeves! Kevin
