GROUPBY and SUMMARIZE seem similar, but they differ in both performance and functionalities. Choose the right one depending on specific scenarios!

I have found that the mix of groupby and summarise also comes really helpful when performing calculations over measures. For example finding the max result for a measure iterating over different groups of selected columns. This video will help me improve my calcs a lot!! Thank you!

I'd been transferring your example to the Adventure Works model I have, got an error, played a bit more only for your comment at 2:10 LOL. Another great tutorial. Thanks

Brilliant. So many takeaways. I'm going to scan some of my complex models and see if I can improve performance with this knowledge. As always, SQLBI is a diamond.

This video is so helpful! A million thanks! Thank you Roberto, can’t wait to implement what I just learned! (it is especially helpful for me as a sql programmer, familiar with “group by”, but not with “summarize”, so I am really glad to learn the usage of both!) ❤

So at about 7:40 you have brand total and overall total. If I understood correctly, you said not to use that method. So what would be the best way to produce the same result, and how would you add % of total for each brand?

Sorry but I don't see the difference between the "Transaction Size" local column in 10:35 and the local table with "A" and "B" as local columns in 18:41. Both of the cases are columns calculated on-the-fly, however, in the first case SUMMARIZE() works, and in second it doesn't. Is this happening because of the Lineage as you say in 18:48?

At 26:55 SUMX is used whereas we really are performing a SUM of the column [@Sales]; is this done solely because we need to be able to add the CURRENTGROUP() as a table reference? Thanks

Yes

@rajeevmenon1975 9 ай бұрын

Need some guidance. I have a table with 3 columns. Date, ID and amount. Amount contains both positive and negative amount datewise, idwise. If the sum of all id is positive, it is a debtor or else it is a creditor. A measure with IF condition is not going into a slicer to filter debtors apart from creditors. How do I do this ?

@lovlyhearts288 9 ай бұрын

I am having one doubt but not related to this content, Using teatedas Dax I connected date table and fact table. When user want to drill fact table aggregation value it's not filter date table untill I drag & make active relationship in the model, Is any other alternative way there to achieve this ?

Thanks to share, I have a question, whats the difference between local column and model column?

@angelgarciadatablog 9 ай бұрын

I think that I understand the different: Local column is a column that was created by dax, and Model column is a column that belongs to principal table. Please, I apreeciate if you could confirm. Thanks.

Confirmed!
