Difference between rows in direct query

[Kolumam]

Hi All,

I wanted to calculate the difference between the rows. Is it possible in direct query using power query or calculated column or measure? Please help. See below pic.

I have the same problem and haven't found a solution yet. There's a bunch of solutions for import, but what about directquery?

Edit: I'm reading from a postgresql database, and decided to do what I needed with sql before bringing the data to power bi.

Hi Koluman

Basically you can create 2 index columns and then self-join the columns to get the "previous row" value

then you just subtect them

here's a detailed post about ti

Hello,

Your solution doesn't work in direct query. It will work in import mode. Is there any other method? @dearwatson
