Thanks Evil for this SQL Script.

[@PiyushAtghara]

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!

[@pavanbv25]

For reference I have created sample data,
create table employee(
first_name varchar(20),
last_name varchar(20),
age int,
salary int,
location varchar(20));
insert into employee values('sachin','sharma',28,10000,'Bangalore');
insert into employee values('pavan','sharma',30,10000,'Bangalore');
insert into employee values('rohit','sharma',31,10000,'hydrabad');
insert into employee values('shekar','sharma',32,10000,'Bangalore');
insert into employee values('Rahul','sharma',33,10000,'hydrabad');
insert into employee values('saurabh','sharma',30,10000,'pune');
insert into employee values('kapil','dev',28,10000,'pune');

[@rareflower88]

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');

[@TrustinData]

Thank you so much for such simplified explanation sir

[@LokeshSabale]

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

[@pravinmahindrakar6144]

[@swadhinsonwane4185]

sir before using partition you should have explained it first. so it becomes easy for us to understand the concept behind the query.

[@vishnujatav6329]

Why so small session as you provide only 2 session a week, I request you to provide one session each day if session are like this much small or create 1 hour session (covering whole topic like WINDOW function in today's session) if 2 session in a week. Thank you
