Table access by rowid

 Hi All,

Today I was asked one quesition, is 'Table access by rowid'  full table scan or index scan?

I was completely confused by this quesion.

In my opinion, this statement always comes along with the index rang (unique) scan in execution plan.

If we look into this statement isolatedly, I think it is the action to locate one rowid with its physical address and it's neither full table scan nor index scan.

What's your opinions on this, please?

Thank you very much,

Leon
