    When using the
    select first_name from TBL_NC where id=5
    we see table scan and you could not clarify that

      Yup i have addressed as well .as you mentioned the query was returning table scan

      It still uses table scan because it has to go through all the records. However, if we add Fname in where condition, then it uses index-seek because the semi leaf nodes or the middle nodes have Fname
