INTERVAL(tmp.start, tmp.end) complains about types being [Column, Column] when in fact they are doubles in a temporary table:

pyvo.dal.exceptions.DALQueryError: IllegalArgumentException: Interval bounds must be double, found: Column,Column

Replacing the start and end columns in the temporary table with an interval column fixes the problem.

there are other issues with interval vs interval queries (specifically multi-interval like the interval.samples used in CAOM) when using an interval column from a temp table... probably doesn't give the correct result. That is the origin of only allowing INTERVAL(double,double) in ADQL.

TBD
