Hi all,

A general Interview question,
What is the way of getting fast access to fetch a row from a table?

I answered in the following way -
Creation of indexes on tables will provide fast access to rows in a table.

But he told - No Indexes are there.
Without indexing, Suggest your answer to fetch rows fastly from a table?

Hi Sipra,

Just he confused you a little bit to test you dear..!

Without Indexing means, it is only possible to use a ROWID function there.

ROWID - It is a Pseudo column attached to each row of a table.
It is 18 character long, blockno are the components of ROWID.
