Merge Multiple data set rows into one row

akordula — Wed, 08 Jun 2016 13:40:09 GMT

I have data in a database in the below format:

Key	X1	X2	X3	Y1	Y2	Y3	Z1	Z2	Z3
12345	x	x	x
12345				y	y	y
12345							z	z	z

I want to know if there’s a way to combine these three records into one record that would be represented like this:

Key	X1	X2	X3	Y1	Y2	Y3	Z1	Z2	Z3
12345	x	x	x	y	y	y	z	z	z

Something tells me that the didin't look like this originally, and perhaps that there's a better way solve this in an earlier stage.

I don't know what kind of real data this is (or is it real, perhaps just training?), but I would definitely consider to transpose the data, much easier to work with.

You're right in saying the data didn't look like this originally, but there has been a change in how the data is presented to us (not controlled by us).

Unfortunately, there's no way for us to revert back to the "old" way and this is how it will be going forward.

Ok. Then it's transpose time 😆
