1. In which way do Oracle uses different indexes?
2. In which conditon index fullscan,table access full,index fast fullscan used? because sometimes it uses table access full instead of index full or fast full

2. In which condition each of the merge join,hash join,nested loops used.


3. Tell me more about hash join in details

4. Please suggest about better sites for this type of information.

Hi,

All Oracle's manuals are available on-line at http://otn.oracle.com/. You may need to register for an account, but membership is free.
