HI Ankit great video. where I can find DDL for this exercise?

[@shashankdhandharia4175]

Great explanation Instead of coalesce function can we use IFNULL function?

[@ankitbansal6]

If it's there in your database you can use. Moreover ifnull will take only 2 arguments while coalesce can have many..

I have imported the superstore dataset from the drive link posted in description and removed duplicates using the below query. Is the query right? with CTE_remove_dup as (SELECT r.*, ROW_NUMBER() OVER ( PARTITION BY order_id ORDER BY order_id desc) AS RN FROM [dbo].[returns] r ) DELETE from CTE_remove_dup WHERE RN > 1 with CTE_remove_dup as (SELECT s.*, ROW_NUMBER() OVER ( PARTITION BY order_id ORDER BY row_id desc) AS RN FROM [dbo].[superstore_orders] s ) DELETE from CTE_remove_dup WHERE RN > 1

Looks good 🙂

[@adityaanand1591]

it's really a good explanation with example..Is there any complete tutorial of yours on SQL.

[@ankitbansal6]

Thanks Aditya. I am planning to create a playlist zero to hero. Stay tuned.

[@adityaanand1591]

@@ankitbansal6 Thanks, I am curious for that playlist. The way you have explained the JOINS through a case study is really very helpful. So, also try to make your playlist with such type of case study for complete course.

[@abhimanyutiwari100]

Thanks, can you tell what is the dateype to store "mm/dd/yyyy" as mentioned in your video. I am using DATE data type to create ship_date column.

[@ankitbansal6]

You can store mm/dd/yyyy in a date data type column..

[@jyotsanapandey978]

I have downloaded the dataset from the description by it still shows the all rows and columns (9994) the given dataset do have duplicate values. What should i do now???

[@sunnysharma5402]

do remove duplicate only on Order_ID columns in Superstore_Orders . It will be 5009 Orders. This will fix your problem
