To be clear, this one is a lot of work and I am not asking anyone else to do this!

nils-braun commented 3 years ago

That looks definitely super cool! I would be very interested in seeing this happen! As I am not so much used to ADQL: if I see it correctly, what is missing are the "geometry" functions - but the general logic of SELECT statements is similar enough to normal SQL, correct?

beckermr commented 3 years ago

That is my understanding as well, but I am also not a user of ADQL.

I agree that the geometry and other special functions are the main target here.
