Hi, thanks a lot for the video. i'm having some issue to calculate the revenue. everytime I try I have this message "Operand data type nvarchar is invalid for multiply operator" . i try to change the data type even if I can see number in the price riders column but then the price column is not regnized. Do you have an idea ? thank you
Thank you for your video. It clarifies what a data analyst will possibly work on the job.
I am glad it was helpful!
Could you have used window function instead of subquery
If you think this is a valid solution please place your query here.
This tutoria was quite grannular. I now have a better understanding of Cohort Analysis. Thank you
Thank you for watching
Awesome as always. I find your shorts informative. In order to pretify or beautify the percentage values we could just nestle or wrapp up the field into format( ) in this way format(sum(sales)/(select sum(sales) from trial_data), "p") ❤
Hi thanks for vedio. I am having trouble in interview to write sql query, any suggestions
Use the playlist on this channel to get familiar with the concepts
This probably.one of my favorites which ive completednand updated and edited and improved on. Kimdly help me though with the meaning of the column 'Son' and 'Pet' and their import to this project. Thanks
Hi Gaelim, I'm Gad. I've successfully completed this project using an addition case for 'Age' thus creating five pie icons instead of 4. Kindly help me with the meaning of the word 'Son' - I don't know what it means it's import and how it relates to every other thing. For the Season Names. I used Transform and new column to change 'Unknown' to 'Select All'. To make become the first among the Tile list on the Slicer Icon. I created a table on Data View, called 'SeasonSortOrder', then created to columns called Season_Names and SortOrder.. Used the Model View to link the Season_Names Columns for both tables together. Then added a new slicer and took out the old one. I still need help to know the meaning of the 'Son' Column and it's purpose I didn't get that in the two videos. Please ........
Another masterpiece, you always deliver great content. Question, should profit margin be revenue - cogs which gives gross profit or profit margin, then divide gross profit by revenue to get profit margin%? Thank you.
I didn't understand how did you calculate the price settings, please clarify
Great explanation 🎉
Hi, thank you for sharing this cool project! I use Mac M1 and have to download Azure data studio instead. Azure couldn't map the dteday column as datetime format and the files couldn't be imported. I had to format that column as string instead and it went through fine. I am wondering if there's any other way to import the file with the dteday properly imported as datetime with Azure?
Great video i love it! One thing if the price is per rider the cost should be per rider as well on the revenue. Minute 22:21. Thank you so much for the video
You solve it a min 44:15 LOL. It was all planned to cover Powerquery? Dude loved your video so much. Thank you!
Great video walkthrough on using SQL and Power BI. I learned so much!
i pray you are muslim and go to heaven.u are so amazing job
I need the link of your giphy animation...
Thank you so much. This video has given me great insight on a real-life project as I transition into data analysis. I appreciate this. 🙌
Great presentation. I have stuck with SUM issue. When I perform Measure = (SUM(Query1[revenue]-SUM(Query1[profit])/SUM(Query1[profit] function, the error pops up "The SUM function only accepts a column reference as an argument." Ive tried different approaches without success. Also, there is a message "cannot find parameter [revenue] Please help.
Is it necessary to remove outliers?
Depends on the business purpose, if these outliers are errors or analysis purposes.

Hello sir, in the weekday column, what days do the numbers 0 to 6 represent?
Thanks!
One tip, you should make a course on Udemy
Thank you! I might just do that!
Hello, during this project I am facing an issue to load data into power bi from sql server. I tried several ways to resolve it but unable to solve. error occurs when I load the data into power bi in the last tab by selecting "Use Current credentials" after this step the error message is " We couldn't authenticate with the credentials provided. Please try again." IF anyone can help me with this it will be very helpful for me.
i hope its rows between current row and 1 following
Im having trouble downloading the csv file from GitHub. I tried ctrl + s but it showed only webpage option from the drop-down list. Could you please walk me through it? Thank you
Can i become a data analyst with a degree in Applied Mathematics?
You can of course. Having a strong foundation in math is a huge advantage
Please keep uploading more Data/Business Analysis Case Study (using SQL or Python)
what is SON?
This is truely awesome. Interesting and challenging query. Step 1. Create two new variables (weekday and period). Extract weekday from the timestamp, Create a new grouping column as period bases on the timestamp using conditional statment case when then. Easy! Step2. From the resulting query in step 1, Count the records based on the weekday and period, and rank them by the total count in descending order. Easy, just like taking breakfast in the morning! Step 3. Select and display the results from the previous step2. Voila.
That could be a good solution if I understand it correctly!
@@absentdata , Sir I was just translating your query using plain english in layman terms. Actually I have replicated your query using food delivery dataset with MySQL. At the end, instead of using he window rank() , just sorted by descendent order. With cte_top_orders as ( -- Step 3 select wk_day, order_periods, count(*) as total_orders from ( -- step 2 Select wk_day, Case When order_place_time in(5, 10) then "breakfast orders" When order_place_time <= 15.5 then "lunch orders" When order_place_time <= 22.5 then "dinner orders" ELSE "late night orders" END as order_periods From ( -- step one SELECT dayname(order_time) as wk_day , time_format(order_time, "%H:%i") as order_place_time FROM food_orders ) as t1 ) as t2 Group by 1,2 order by -3 Limit 2 ) -- step 4- Final Select ROW_NUMBER() over() as Item, order_periods, total_orders From cte_top_orders ;
Can we make the AVG of the avg_price as sub query??
That would not give the average of all the priorities. That would just be an average of all the state average
@@absentdata the first avg make all priorities 8 and think if makes a second avg of the new value of the old avg Wil give us 4 priorities that's mean it's working right?
i love your videos it's so simple

Thank you. I'm glad it was easy to approach
Thank you for this video I love it. but when I try to import data, the columns in the temp and atemp sections don't have dots (.) why? even though the data type is already float. Please reply
