Hi Ankit, can you please kindly help the below requirement.
create table #temp ( DepartmentId int, Name varchar(255),Hiredate date,Sal float,Ruleid int)
Insert into #temp (DepartmentId,Name,Hiredate,Sal) values ( 10,'Sai','2021-10-23',5500)
Insert into #temp (DepartmentId,Name,Hiredate,Sal) values ( 10,'Sairam','1999-10-23',6000)
Insert into #temp (DepartmentId,Name,Hiredate,Sal) values ( 10,'Saikrishna','2002-10-23',3000)
Insert into #temp (DepartmentId,Name,Hiredate,Sal) values ( 10,'Sair','2021-10-23',5000)
Insert into #temp (DepartmentId,Name,Hiredate,Sal) values ( 10,'Raj','2015-10-23',8000)
Insert into #temp (DepartmentId,Name,Hiredate,Sal) values ( 10,'SRK','2021-10-23',5000)
Create table #Rules (Departmentid int,Ruleid int, Condition Varchar(2000))
Insert into #Rules values ( 10,1,'Name like ''Sai%''')
Insert into #Rules values ( 10,2,'Hiredate >= ''2000-01-01''')
Insert into #Rules values ( 10,3,'sal >= 5000')
output
Departmentid Name Hiredate sal ruleid
10 Sai 10/23/2021 5500 2,10,30
10 Sairam 10/23/1999 6000 2,30
10 Saikrishna 10/23/2002 3000 2,10
10 Sair 10/23/2021 5000 2,10,30
10 Raj 10/23/2015 8000 10,30
10 SRK 10/23/2021 5000 10,30
DepartmentId is used to join #temp and #Rules.
check each condition dynamically from #Rules against the corresponding rows in #temp.
If a condition is satisfied, concatenate the Ruleid value from #Rules to the existing Ruleid in #temp

yaaaaaay!!
Hi Ankit, You have made this video at the correct time, I was looking for something like this. Could you also make a project on end to end problems while loading data in CSV to MySQL. I recently had a issue where I was not able to fully load all the data , only partially even though I did null treatment. Please make a video on it and also post it in your LinkedIn once you have done it so i may get notified about it
Sure
Hello Ankit Sir, am a fresher and am looking forward to start my career in data analytics or data engineering field. This video is awesome and very helpful for me. Thank you so much for making the End ot End videos like this. And the way you explaining each and everything is very nice and clear. Keep it up Sir
Keep it up 👍
Thank you so much
You're most welcome
First of all, thank you very much for the project. But there’re couple of concerns which you may have overlooked -
1. In every query where we’re doing analysis based on sales, I guess it’s better to consider sale_price*quantity as sales rather than sale_price only
2. In the last problem, profit should have been taken into consideration rather than sale_price
But again I’m repeating that, above are some modification we can make to get the best business answers, otherwise in the video you’ve shown the approach how to handle an end to end project - from that pov it’s absolutely fine. We students can make necessary changes.
Thanks for the feedback. Appreciate it 🙂
Sir please upload more SQL projects with datasets from kaggle.. Thank you for this..
how do you document your findings. please make a video on how you put everything together for a portfolio showcasing your skills in python and sql
Thank you ankit it's really helpfull.
Can you make a practical video on A/B Testing plzz
Sure
Hi Ankit, Wonderful Explanation. Can I have those DDL statement in SqL Server. Not able to find in Github
Can't add the ODBC Sql Server even after having the MySQL that was installed for working on your SQL Course. I am getting an error message saying TEST FAILED. Can you please share any link that can help us to get that server name present in the list of servers available to connect or better a follow up video showing how to do it on your system.

Thank you so much Ankit bro

Your a goat 🐐 in data filed sir
In the last question of sql
Should we calculate growth by profit change or sale change because the question is for profit change
Also in total revenue quantity of each order is not included
Bro can you pls help me ! Download the dataset in vscode when it runs it show an error
We can use power bi

Hello Ankit when I am Importing date from python to SQL and running code in my Jupyter Notebook I am getting below error
AttributeError: 'Connection' object has no attribute 'cursor'
Please let me know
Sir when you solved the first question why didnt you multiplied the quantity column with the sale price?? For total revenue by product I'd?
Yes, I think likewise. Revenue should have been qty*sale_price
Hi Ankit
Can you please also show us
How to add triggers
To update the data every month on database
Thanks
Hi all, i am not able to see my odbc drivers details for sql.can anybody please help me out
Can this be done using VScode?
For first question, Don't we need to multiply sale_price with the quantity for revenue generated for each product?
We can do that. I assumed it was total sales in the sale price.
@@ankitbansal6 ok sir
same question. my answer is
SELECT top 10 product_id, SUM(sale_price * quantity) AS total_revenue
FROM df_order
GROUP BY product_id
ORDER BY total_revenue DESC;
where can i find dataset ankit ?
with t1 as (select month(order_date) as month1,sum(sale_price) as sales1 from orders where year(order_date)=2022 group by 1),
t2 as
(select month(order_date) as month2,sum(sale_price) as sales2 from orders where year(order_date)=2023 group by 1)
select month1 as months,sales1 as 22sales, sales2 as 23sales from t1 inner join t2 on t1.month1=t2.month2 order by 1 asc;
another way for the year on year query
Not able to kaggle API understand
I'm 40 and I am trying to switch career to Data Analytics from a completely different background. I learned PowerBI + SQL. Can I get entry into this field with these two modules? Can I learn Python later have a good career? That is my plan over the next 5 years.
Yes that works. Make sure your SQL is strong .
@@ankitbansal6 Definitely. I was recommended your channel for SQL by a youtuber and actually made a lot of progress in the past two months from your channel. Thanks is very small word for the effort you put into your content. But Thanks anyways 👍😊
Brother I'm 30 and trying to get into data analytics from the Mechanical domain.
Many times I get frustrated and lose hope but your comment restored my faith in the process.
I wish you all the best for your endeavours 👍.

Hello ankit i followed your video its great to learn . I have one scenario where i have two database one is postgrey and second mysql. what i need is there are 25 lakh product in mysql product table which has pricing and inventory which i want to update in postgrey database based on sku column which will be same. I used query and api its taking 4 to 5 hours to update can we do something with database to update pricing and inventory using procedure database to database. Please suggest
Using python you can move data from MySQL to postgres and then run update on postgres
Sir will not we multiply the quantity with sales price to get the overall sales price of particular product and then sum it????
We can do that. I assumed it was total sales in the sale price.
@@ankitbansal6 ok sir🙌
Hi sir
I have a doubt
Top 5 highest selling products should be in terms of quantity right?
sales.
Sir will we have a PowerBI course like tableau ?
Yes After Tableau
Can we expect something related to cloud as well?

i didnt understand why did we use kaggle Api. We could have directly downloaded the dateset from kaggle and read the file using pandas ,right?
Yes but how we will learn to use API 😄

bro can you show us an project where you have done the analysis in python why did you do that and store in s3 bucket and so on .Can you make an vedio on pyspark as well
Sure
hi i am not getting .kaggle folder in my pc why so
You can create it .kaggle
Hey Ankit I'm my PC isn't showing any .kaggle icon in my users - username- file how to get that.. I have installed kaggle pip install kaggle.
Create yourself
Got it
Sir kindly provide the dataset kaggle link
Description box
I am unable to extract zip file 😢
Do it manually and continue
For the query to find each category which month has highest sales, you can do this as well in mysql which looks easier -
with cte as
(select category, sum(sale_price) as sales, date_format(order_date, '%m%Y') as order_month from df_orders group by category,order_month order by sales desc)
select category, order_month, sales from cte c1 where sales = (select max(sales) from cte c2 where c1.category = c2.category);
sir in the last question I am getting a little bit confused it tells about but it is solved on total sales growth can you clarify for me, please
with cte as(SELECT sub_category,year(order_date) as order_year,sum(profit) as total_profit
FROM df_orders
group by sub_category,year(order_date)
),
--order by sub_category,year(order_date)
cte1 as(
select sub_category,
sum(case when order_year=2022 then total_profit else 0 end) as profit_2022 ,
sum(case when order_year=2023 then total_profit else 0 end) as profit_2023
from cte
group by sub_category
--order by sub_category
)
select cte1.sub_category,((profit_2023-profit_2022)*100/profit_2022) as profit_growth
from cte1
order by profit_growth desc
this is my solution. please rectify if I made any mistake.
