📊 WHAT IS POWER BI?
Power BI is a business analytics tool by Microsoft. It creates a working environment suited for normal users, meaning tasks such as data extraction, cleansing, analysis and storytelling; these are made easily-accessible to citizen-users, and extendable for technical users. At face value it provides visually-stunning, interactive dashboards, but it’s built on top of so much more.

Hi i have 3 tables. The first one is the main fact table, the second one a bridge to connect between the first and third tables as I want to get a column from the third table to the first. Two questions are after i merge the third and second table should i expand the column to then use it in the first table. Second question is the second and third table i wont be using so should i turn off enable load and report refresh for both those tables

Hey Fernan, thanks for another great video! Could you tell more about Query folding in Data Flow and its relationship with the PowerBI desktop? My understanding is if my source is a data flow, I will not have Query folding in the dataset that I’m creating in PowerBI desktop, is this right?

@ayandapeter1681 2 года назад

Thank you Sir, that was a good explanation

Thanks for watching my videos as always Ravi, appreciate it!

@Adil-wq4nd 2 года назад

Great video I have a much better understanding of query folding, as a side question have you come across the terms query collapse/collapsing or is this the same as query folding? Thanks again

@jonathanjacob5453 Год назад

So query folding is just the SQL statement that Power BI builds for you in the background?(in case of a SQL database) And this is important because the a database is optimized to return data more efficiently that you could do the various actions locally on your desktop.

@harryfeng4199 2 года назад

so wouldnt it be better if i just write in SQL instead of query folding

@davidgitau8825 2 года назад

I understand this stuff. Kindly include a bigger font on your video. Sometimes we struggle to see.

@slmn9676 2 года назад

thank you for sharing information .....

Thanks for watching!

@@SolutionsAbroad But in my case, it seems like I have to merge column "Category" first before I can Group By. Because if I Group By first, I will never know sell price of each Category an employee sold. So it means I will lose the query folding early in applied steps, and when I Close and Load it will take longer. In my case, it was inevitable 😔

@Magdoulin Год назад

Ok, I understood what does the folding mean but I didn't get the benefit of it actually, does it make the query faster? Is that the point? And if these steps could be done thru the source? Why wouldn't I include the steps in SQL itself? Another point, does it work for all SQL source queries? I got a SQL query and the Source step doesn't seem yo have native query, what does this mean?
