In addition to the other replies:

Let’s see the first one: How can i change the query so that. I got exactly same question on index full scan and index fast full scan in the real application. As it exists on the disk. In this plan we have a simple clustered index scan. Index fast full scan is otherwise called as fast full index scan also. Index fast full scan can. This index read is unsorted. > select /*+ index(g) */. How to avoid fast full scan of index?

I got exactly same question on index full scan and index fast full scan in the real application. > recollect when i was not able. As it exists on the disk. In this plan we have a simple clustered index scan. Ensure that indexes exist on the key value and that the index has been. Maybe you could use index compression. This access path usage multiblock io to perform the index scan. An index fast full scan reads the entire index as it is i.e. Select * from bigproduct where name like '%ll road rear%'. An index with so much repeated values should be an attractive target for compression.
