From the black-box UDFs we cannot tell exactly how this traslates
to plain SQL
Is it this:
select count(*)
from Object o1
,Object o2
WHERE o1.ra BETWEEN 90.299197 AND 98.762526
AND o1.decl BETWEEN -66.468216 AND -56.412851
AND o1.decl BETWEEN o2.decl - 0.015 and o2.decl + 0.015
AND o1.ra BETWEEN o2.ra - alpha(o2.decl, 0.015) AND o2.ra + alpha(o2.decl, 0.015)
;
or the one below?
*/
select count(*)
from Object o1
,(select decl - 0.015 as decl_min
,decl + 0.015 as decl_max
,ra - alpha(decl, 0.015) as ra_min
