[@dikshachawla2475]

hi mam..can you explain in hindi?

[@bodalarupesh5024]

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

[@anandprakash2478]

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

[@rohitkarnatakapu4760]

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

[@anandprakash2478]

exactly, i was wondering after watching like that
