For those of you writing your sql query on Postgresql. You can create the same table here in this Postgresql-compatible format: CREATE TABLE int_orders ( order_number integer NOT NULL, order_date date NOT NULL, cust_id integer NOT NULL, salesperson_id integer NOT NULL, amount float NOT NULL ); INSERT INTO int_orders (order_number, order_date, cust_id, salesperson_id, amount) VALUES (30, DATE '1995-07-14', 9, 1, 460); INSERT INTO int_orders (order_number, order_date, cust_id, salesperson_id, amount) VALUES (10, DATE '1996-08-02', 4, 2, 540); INSERT INTO int_orders (order_number, order_date, cust_id, salesperson_id, amount) VALUES (40, DATE '1998-01-29', 7, 2, 2400); INSERT INTO int_orders (order_number, order_date, cust_id, salesperson_id, amount) VALUES (50, DATE '1998-02-03', 6, 7, 600); INSERT INTO int_orders (order_number, order_date, cust_id, salesperson_id, amount) VALUES (60, DATE '1998-03-02', 6, 7, 720); INSERT INTO int_orders (order_number, order_date, cust_id, salesperson_id, amount) VALUES (70, DATE '1998-05-06', 9, 7, 150); INSERT INTO int_orders (order_number, order_date, cust_id, salesperson_id, amount) VALUES (20, DATE '1999-01-30', 4, 8, 1800);

Hello Ankit I have one question. As you said we can use 1 preceding and 1 preceding function which works similar to Lag function. But let's say when there is too much data in the database and if we use the " 1 preceding and 1 preceding " function then how the system will behave in terms of performance. Can we use " 1 preceding and 1 preceding " for query optimisation???

Hello Sir, Can you explain how unbounded preceding and current row is different from just order by order_date. Query would give the same result I believe

Hey Ankit, I am getting syntax error on 'order'. pls help. @7:59 select salesperson_id,order_number,order_date,amount ,sum(amount) over(partition by salesperson_id order by order_date) from int_orders; Incorrect syntax near 'order'.

Great content and clear explanation of aggregate/window functions. With using over (order by order_date), result set will be sorted whereas using over (order by order_date with rows between unbounded preceding and current row) result set will not be sorted in any order. Is that right ?

Hi sir and everyone, I am stuck with a query: suppose we have a transactions table with (timestamp, user_id, sender_id, amount) fields how to pick those transactions that happen within an hour by a particular user (suppose a user starts 1st trans at 8am, 2nd at 8.25am, 3rd at 9.05am, 4th at 9.50am, 5th at 10.45am... so all of these records must be picked starting from 8am to 10.45am) can anyone please suggest an approach to solve this... 🙏

What do you mean by within an hour. You are saying all the transaction should be picked up but they are accross multiple hours

@@ankitbansal6 we have to pick series of transactions uptil time between two consecutive transactions is less than one hour Eg - for a user he makes following transactions in a day 1. 8 am 2. 8.25 am 3. 9.10 am 4. 9.45 am 5. 12.35 pm 6. 3.20 pm 7. 4.45 pm 8. 5.15 pm 9. 5.50 pm 10. 10pm Out of above transactions we should be able to pick trans no 1,2,3,4 since in this series the time diff between consecutive trans is less than an hour, likewise we should also be able to pick trans no 7,8,9 here also diff between consecutive trans is less than an hour... Ps - if you could provide me anyway(discord server, mail, etc) to share the sample dataset and full query requirement for much better understanding ??
