Very helpful. Thank you
Thank you
all the best to you and everyone you care about :)
After watching dozens of videos in english, portuguese, on youtube and paid classes, trying to understand how row context, filter context and CALCULATE function works, I finally could comprehend that concept by watching this video. It's so simple that I still don't believe it.
Thanks @PragmaticWorks for this video.
DAX cant be explained better, Your DAX and Modelling video is the reason behind the appreciation I get in my office.
Glad we could help! Thanks!
Is that a mere compliment or the true words?
Oh. It's a way to do sql queries inline in PowerBi without having to write SQL queries. Neat.
Yyyyýyyyyy4y6

Mmm
Richard I usually don't comment on videos but you are completely out of this world. Your experience in this is so amazing and looking at you do all this completely shows you have gone a long way with it. The way you teach, make references and use different formulars is just so great. Thank you so much.
Thank you so much 😀
I have been learning DAX by myself for the last few months, and this is the first video that really manages to explain these concepts in enough depth and in a way that is easily understandable. Thanks so much!
Glad you enjoyed!
PW is currently the best learning platform as far as BI is concerned, they have assembled the best Nerds in the field. The most interesting part is the passion with which those guys have for the subject. I have spent a lot on their platform and I can tell you that it is worth every penny. You basically pick up the materials and apply them to your job and you are fine, it is that effective. Mitchel and Manuel are my favorites
I find tutorial videos from Pragmatic Works are simply the best! As someone who recently started working with Power BI regularly, it was good to come back to the basics in order to understand why i made those DAX mistakes I made and how to correct those and prevent them from happening again. I also watched the series from Pragmatic Works on Data Modeling- highly recommend it!
Thank you so much! Happy to help!
The course has been taught at the right pace and the resources provided has given it a perfect hands-on training experience. Thank you so much Mitchell!!! Really appreciate the time you have taken for this. looking forward for your other courses and advanced DAX workshop.
Clear as crystal water !. Excellent communication skills and knowledge!. Thanks!
Thank you for the huge complement! Always glad to help.
So, I have watched many Power BI / DAX tutorials, but yours is the tops! Sam McKay at Enterprise DNA is very good, but the way you describe how and why to do things and how measures works is just the best. I was one of the ones who always created a separate table/group for Key Measures, but your method of creating a folder for each table and putting the measures in the table outside the folder is brilliant and a lot more intuitive, since many times you're also using other fields from that table with the calculated measure. Just a superb course - thank you so much for this!!
This DAX video is a masterpiece! I've learn't so much from this. I like how the course is broken down into segments and you explain what each measure is doing and how it does it. I have been available to comfortably follow the recording, and do the columns and measures myself, without having to pause or rewind to listen again. Please keep these coming! Thank you
Years of experience and passion for Business Intelligence compressed into 3 hours. Incredible speed throughout the entire session but not a single redundant sentence. Wow.
Thanks for this awesome feedback Dave! Glad you enjoyed the video.
This is a masterpice! All core topics of DAX clearly explained!
Mitchel, I am new to DAX, and yet I remained glued to your session for complete 3 hrs. You are simply awesome.
Awesome, thank you!
I saw many Power BI Videos, but your training skills are really awesome.
This is great feedback Rajat, thank you so much. I had a lot of fun and I'm glad you enjoyed the training.
I’m slowly working my way through this, excellent, thank you.
Richard, great job with breaking down the concepts - I've been using Power BI and DAX and took this course as a refresher but I definitely learned SO MUCH MORE, I appreciate how you break down the concepts into manageable chunks and gave great examples as well :)
Thank you for an excellent course. The pace at which you explained things was perfect, without any unnecessary repetitive statements. Examples were excellent, although I am using it for engineering data and not business related, I could relate your exams to my specific type of data.
Amazing, followed the whole 3 hour video! Awesome, right level of difficulty and content for an intro video
this is just amazing, straight to the point, well explained , with examples and real case scenarios. Well done!
The best Dax instructor ever! I've watched a lot of videos about DAX, including videos from DAX gurus and I can affirm this video is the best of all. Hard concepts are made easy to understand with clear examples, very good teaching technique. Kudos to the instructor!
This is incredible feedback, thank you Carlos, I am glad you found the video helpful. -Mitchell
Yes I agree with you that he's the best Dax instructor. Do you know where I can watch more of his videos?
Great tutorial, this was intended for DAX but it is even explaining PowerBI report better than any video I saw on report design.
Wow! This is roughly three hours well spent. Thanks Mitchell and Pragmatic Works for this super awesome video. Really enjoyed every bit of it. Kudos!
I can't be more thankful enough. I have been looking for something to practice what I had learnt from the DAX book and a few courses I have done previously. But it's all too complicated if you don't have examples to practice on. This video does just that, it gives me examples to work with. I know a lot of this stuff but I am never confident when it comes to applying these concepts so this is where this tutorial comes in handy. You need to have initial background but after that, if you have to gain mastery you need practice and this is THE best video I have found for practicing. Kudos! You are doing some really awesome work!💕
Wow this is an amazing training. I am new in Power Bi and have found this the most helpful DAX training
Great session, thanks to the Power BI master!
It was an outstanding lecture. Explanation was crip and clear. loved the style. Great Job MP
Thank you Mitchell for explaining DAX so intuitively. You helped me get a good grip on DAX functions.
One of the best training videos I have seen regardless of subject!
Glad you enjoyed it!
Richard, I have to say that you are a great teacher, you explain concepts that could be difficult to understand in a clear and understandable way. You are very didactic and I learn a lot from your teachings.
I read "Learn to Write DAX" of Matt Allington, and this video definitely consolidates my takes on the book. The concepts become much easier to understand when you start with Calculated Column and Row Context first.
Thank you very much Mitchel & Pragmatic Works for this amazing course.
-Great examples (real world examples).
-Great explanation.
What a teacher! He shows experience and ability to explain. In the 99th percentile of the best tutorials I've seen on UA-cam.
Coming from a Tableau user, I have to say that this video is GOLD. It's hard to find such a good explanation for a 'Filter Context' and all concepts in Time Inteligence (YTD Measures, Prior YTD Measures, etc). So again, Thank you!
This is great. Finally understanding that the aggregate roll up of data is added to the DIMENSION tables using the navigation functions. I was missing that part. Thank you!
This is the best DAX video i have encountered on this platform. You sir are incredible
Best of the best I'll say. I'm watching it twice. Feels great to listen. Feels great to understand. Many aha moments.
Glad you enjoyed (:
Super trainer! I am a completely beginner of this DAX but you enlightened me. Thank you for sharing these wonderful session.
You are simply great!
I am a super user of PBI, yet I was counting a lot on Excel to prepare the datasets before exporting them to PBI.
Now I can skip off such transitory phase (which needs double efforts and may cause some discrepancies) and make everything inside PBI.
Really appreciated 🎉🎉
God bless you bro I have power bi exam tmr and you helped me lotss
Bravo, the most friendly and usable lecture so far.
This is the first video I've seen that explains DAX concepts this thoroughly and in a way I understand. I hope I find more of these. Thank you!
Great to hear!
This has been the most informative lesson on DAX I have ever had. After this I'm redoing my current reports from scratch lol. Great stuff
Probably the best explanation of filter context I've seen so far. Happy to recommend it to some colleagues who are just starting to learn DAX.
Thanks George!
Wow, very detailed and precise explanation. I'm glad I jumped into this video
This is a excellent training video, thank you!
This was an outstanding presentation. You cleared up a lot of things for me. Thank you!
Probably one of the best DAX videos I have watched on youtube till now.
Excellent training with great topics. Thank you.
A fruit full session on DAX. Thanks
So far the best DAX content ever I have come across. Nicely structured and to the point content.
That's a huge compliment! Thanks Aditya, I had a lot of fun.
Thank you so much for your amazing tutorials.
Every time I am thinking about a question it magically gets answered right away in the very next chapter or through the questions during the live session.
I am very grateful, amazing job
Excellent class! You were so easy to understand, although I have been working in PowerBI for a while now, so I'm sure that helped. But, I know I needed more understanding of DAX and you're helping me get there. Thank you so much!
Thanks for watching!! Glad you enjoyed it.
I just cant hold back my appreciation to you guys. You are just awesome. Thank you for all the effort you put into your tutorials. This was really masterpiece.....:)
Wow, thank you!
It's an amazing session, Thank you so much for publishing this over ..
I think this is the single greatest tutorial video on a subject ever. Mad to see that such content is available for free.
Fantastic bit of work.
Glad it was helpful!
Wow, that's awesome praise lol!! Thank you MrArp - Mitchell Pearson
Great training, excellent presentation!! Thank you Mitchell!
Thanks so much, I had a great time :)
Absolutely amazing 3 hrs. course, as many of you I come from the SQL world so DAX has always be confusing; this course cleared so many questions. Kudos to Mitchel Pearson for an extraordinary compilation of knowledge!
Thank you so much, keep up the excellent work.
Glad it was helpful!
Thank you Mitchell for the wonderful class, i am quite very new to DAX but was still able to follow along the explanations. I will continue to practice and will follow your personal UA-cam page for more awesome contents
Wow, cannot thank you enough for putting this course out there, and for free. Pragmatic is definitely the best when it comes to learning Power BI. THANK YOU!
That is an amazing compliment. Thank you!
Richard, WOW some of the best teaching of a challenging topic I have ever seen. I'll be signing up for the boot camp as I have really enjoyed watching the 3 hours.
amazing lesson! this is very helpful. learned a lot
Wonderful session on Dax...! Those who want to be clear about the basic idea of the Dax with some used case.... please do watch this!

Calculate 00:49:20
Such a great course!! Impressed by how 3 hours went by, received so much information and yet, not feeling overwhelmed because everything was so well explained.
Glad it was helpful!
wow! This is the best video on DAX/PowerBI I have come across. Been working with PowerBI 5 years but this clears up so many concepts in one go. Not sure why this is considered intro :) This really is PowerBI start to finish!
Thanks Ali, glad you found the video helpful!
One thing I know, you can never go wrong with Pragmatic Works. I have been following you guys as a go-to when it comes to BI or now-Cloud BI for last 10 years, everything you guys do to stay ahead of the what's coming next in technology, your free resources, power-packed webinars - are truly marvelous.
Thank you for that kind comment, we appreciate your feedback and your follow!
Microsoft makes things complicated and you make Microsoft simple.
Excellent video, learned a lot and a big plus for explaining everything in simple terms 👍👍
I wanted to take a moment to express my sincere appreciation for your explanation. Your insightful and articulate approach not only made the complex subject matter more accessible but also sparked a newfound understanding and curiosity within me. I wanted to learn DAX since many months and watched many videos but was not satisfied with them. This video made me understand, so well, thank you so much. I sometimes subscribe or like videos, but this is the first time I have commented on a video, what an explanation 👋👌💯
Love this Video very new to PowerBI and DAX coming from a python background so it was hard to wrap my head around how filters did not have to specified in the calc if the measure was made outside of the column and a relationship between tables existed.
I ended up changing a lot of my code to just use a simple Calculate( (total) , filter) expression instead of SUMX, if logic etc
😅
Yep, this was great content with an excellent style of presenting! Many thanks!
A big thank you to you Mitchell. Really enjoyed the class and learnt a lot so far.
Mitchell Pearson! just wonderful!
Thanks Jiulu and thanks for taking time to comment! -Mitchell Pearson
What a great educational presentation! Thank you Mitchell for sharing your knowledge and making it easy to follow and understand . Your presentation was very much appreciated! Recommending it to all Power BI enthusiasts I know.
Thank you Fair, glad you enjoyed it and it was helpful!
This is such an amazing extensive and robust DAX session I've ever watched. Thank you for sharing.👍👍👍
One of the best session on DAX, loved the contents
Thanks for the info on the navigation functions! That in itself helps solve a majority of the learning curve issues I have faced learning DAX.
better explanation than some paid courses.👍
Thank you! Glad to help :)
I watch this every time I need a refresher on DAX.
Another refresher lol
Hi Progmatic Works, I enjoyed every single minute of this video with perfect explanations of the context, best practical examples of senarios that a function can be applied and all technical know hows that mentioned. Thank you very much.
The only thing I'd like to check is the version of DW of this video. I faced a number of issues when doing my own DAX coding, like the slicer for countries does have impact on measures like US sales or Fiscal YTD Sales does not function properly(Date table does not have a Date column but FullAltenateDate colum which is Data not DateTime. I appreciate if you could tell us which versions of Power BI and Adventure DW is being used in the video.
Thank you so much for taking your time to explain these concepts.
I just have to leave a comment! This is the best DAX tutorial I have seen. I didn't expect that I'd be fully understanding of the concepts at the end of the day, and I did!! Thanks so much for the awesome explanation and demonstration.
Wow, thanks!
Really appreciated Michell for the workshop, it's really easy to understand and catch up.
One of the best tutorial I ever watched on DAX.
Thank you so much for this great content! It helped in securing my first powerbi job!
Automagically... love it. This has been a phenomenal training!
Thanks Jamie! Glad you enjoyed the training!
there are a lot of DAX experts online but not everyone can explain/teach clearly, or in a way thats easy for people to follow, amazing , thanks for the video
Glad to help!
Mitchell is the best at explaining with supporting examples very advanced concepts in very simple words.
Thank you very much for this course. I have learned so much. The explanation is very clear and precised. This will help me to understand DAX functions better. Please how can I access the exercise files?
Thanks for sharing a great experience, it cleared a lot of things in this workshop, thanks once again for sharing a real-time example.🙂
Well done Mitchell you did a great job. I've really been struggling with DAX but with this I'm good to go. Thank You!
The explanation of the concepts in DAX is really good. Thank you, Mitchell Pearson! I will definitely enroll in Pragmatic Works ODL in DAX soon!
My pleasure!
Huge thanks to PW and Mitchel for this wonderful tutorial, watching the ads as my way of saying thanks
Your explanation is really awesome and this definitely helps anyone for improve their career on PowerBI
Congrats! Tried other (paid) courses for DAX induction, no result; from your free tutorial I feel I am almost there :)
Very clear and concise explanations. I'm just starting out with Power BI and watching this boosted my understanding significantly. My models and reports are already improving. Thank you!
Great to hear!
It covered simple and complex concepts about DAX in a easy way!! thanks very much!!
Thanks Daniel, glad you enjoyed it!
Thank you, for me this it was the best DAX presentation, I am preparing the DA-100 exam and now I am confidence with DAX part for my Certification of PowerBI
