And while it did the trick, I was wanting, for no particular reason, to also have the total number of objects and the percentage. Again, no particular reason. It might be able to be done with a window function, but that is also something that I have limited familiarity with, so I decided to approach it as a CTE. And it works nicely. The objs CTE gives me a count of each object type while the tots CTE gives me the count of all objects. By giving each CTE a column with the value of 1, it’s easy to join them together then calculate a percentage.
That’s one of the nicest things about SQL as a language: you access metadata the same way you access regular data, so that technique can be used to query other data sets as well.
