Regarding Index Usage
AB312062Mar 26 2013 — edited Mar 27 2013Hi
I have some doubts regarding Indexes:
1. What is the difference between the below 2 index usage scenarios:
/*+ index(a index_name) parallel(a,4)*/
/*+ parallel_index(a,index_name,4)*/
Are both these same?
2. What is full index scan and fast full index scan?
3. I have a table created in database and it has a few indexes on some columns. How can I check whether the index is Bitmap or B-Tree ?
Thanks
