    Good quality 'structured' learning material is rarely available for free. I can understand the hard work that goes into it.
    Thanks for all of it!

    The exact SQL that has all of Sumit's data and correct names, salary and ages, and exact column names used in this example:
    CREATE TABLE employee (
    firstname varchar(20),
    lastname varchar(20),
    age int,
    salary int,
    location varchar(20));
    INSERT INTO employee VALUES ('sachin','sharma',28,10000,'bangalore');
    INSERT INTO employee VALUES ('shane','warne',30,20000,'bangalore');
    INSERT INTO employee VALUES ('rohit','sharma',32,30000,'hyderabad');
    INSERT INTO employee VALUES ('shekar','sharma',32,25000,'hyderabad');
    INSERT INTO employee VALUES ('rahul','dravid',31,20000,'bangalore');
    INSERT INTO employee VALUES ('saurabh','ganguly',32,15000,'pune');
    INSERT INTO employee VALUES ('kapil','dev',34,10000,'pune');

    We will also use order by under over clause after partition by because it gives an answer in a sorting manner
