Fwd: ADQL-2.1 Working Draft available on the repo

[Marco Molinaro]

Dear Ger,
I forward your enquiry to the DAL mailing list, being this of interest
to the full community.

I have, personally, not a strong opinion on this.

The reserved ABS keyword, together with other ones referring to
functions in ADQL, comes from the initial ADQL specification, now
under revision.
So the answer can be as simple as the second paragraph in $2.1.2 of
the spec (refer to either 2.0 or 2.1 version): special meaning and
escaping solution in place.

I let the other ADQL experts comment deeper on the topic.

Cheers,
    Marco

Hi Marco,


I'm a bit surprised to see that function names like ABS are reserved
ADQL keywords. A parser does not need it to distinguish between
function names and identifiers. So why is that?


Cheers,

Ger van Diepen
