I have created a table called Student and added recorded to them.
Then i created index for student table.

CREATE INDEX firstIndex
ON student(stu_name)

I went to an interview,They said when we making indexes it creating a hash value for colum and it creates a new table and save it in that table.

I'd read a primer on database indexes (ask Google). Some systems offer meta-data tables that contain information about the indexes, but aren't actually the index. For example, in some software creating an index would add a line to a table to show the existence of the index. But this is purely representational.

I am using MySql Server.
