Sorry to disturb you again Mr.selvan

So,full table scan comes into picture only when you have index created on the table(column) to make comparision.
(That is whether to make use of index or not).
If you do not have any index created on the table(column) and the selection criteria is not using that column,then full table scan will be done with select statements (irrespective of where condition).
Is this what I analyzed is correct Mr.selvan?
