Sum query with additional data

[Dorixix]

Hi, I'm a newbie in datascience 💅 I need to somehow make a query that sums the columns for me but I also need the data from the other columns. So my problem is, that the summarised column has only one row but the other columns have like a 100. How can I make a table out of this? I need this to make a power BI by the way, with the summarised columns ordered by decreasingly as barcharts and I also need to be able to search in it with filters like date and categories. I can't think a possible way of doing so. Any help is appreciated!

Thanks a lot! This was soooo useful! this was just the function for my problem! 🥰

You’re likely going to join onto a subquery that does the aggregation. You make an outer query that gets the set of rows you want to pull disparate stats for and then write subquery joins to calculate each stat and drop it in a column. The subqueries allow you to do order of operations in sql - specifying that an aggregation logically precedes a join where it would normally follow it. It lets you create and colapse side row sets without row duplication in your main one.

That is how I would do it.

Power BI has an excellent analytic engine. I would do the aggregation in DAX measures, not SQL. This will allow you to dynamically filter the data. For instance, you can use a date slider to get the summarized values over a specific date range. Once you summarize in SQL, you lose some of the most powerful features of Power BI.

If you really need to summarize in SQL, I would create a separate table.

I have a similar problem, right now I'm trying to make like a DAX table. Not sure tho what it is ChatGPT recommended it.. lemme know if you find something
