The structure of that index make different structure so it will affect the

It means it take the different total time to query data using that indexes.

Subject: index question
hi gurus,
this is my question.
Will "Changing the column order in the index definition" affect the
result?
E.g.,
Are the following statements same or what?
Create unique index abc on table1(empno, ename)
Create unique index abc on table1(ename, empno)
