Best explanation indeed. I actually fixed a bug in the code at work due to the reason that condition was applied before lag function. Thanks Kiran.
Very well explained 👍🏻
Is there a way to group variable and then use lag function so that one id value does not go to second id.
Once you are done with lag function in which you have lag from from one id to another. All you need to say is . if first.id then newcolumn= .
Nice one , I wonder if we have lag2, lag3,....lagn..?
yes, we do have, but just want to touch base basically on what could go wrong if lag is not used properly
Very well explained.
