Bring 1 record randomly from each category
The code I posted does exactly that - it returns one randomly selected category row per project row. If this solution doesn't exactly match your requirements, then you must provide a more complete explanation of what it is that you are expecting to see. It would also help if you were to provide some sample data which folks can code against.
Have you checked that the four projects at the top of your output - in the image - have more than one category?
