how it work can any body give me proper guide line about inline view

If you are asking the definition of an "inline query", I can give you a simple example. Consider the following view:

    create or replace view MyView as

        select 'test' as test from Dual

    /

    select MyView.*

    from MyView

The following is the "inline view" version of the same query:

    select MyInlineView.*

    from (select 'test' as test from Dual) MyInlineView

I hope it helps you...
Best regards.
