Ok I have a query in a program that looks something like this
select
reference_number as foo,
'(10,10)'::point <-> point(x,y) as distance
from imagemap
where
index_number = '2322' and
block_number = '140'
order by distance
limit 1;
I wanted to add a clause in where 'and distance < 30'
but according to the postgres manual it says I cannot do that for WHERE or
HAVING clauses, instead use the real name.
However dropping the 'as distance' from my query gives me a column name of
'?column?' which happens to not be worth a dang thing.
How can it be done?
(I suddenly have a feeling its going to require a subselect)
Ryan
