Re: Searching Point Column

Perhaps not the most efficient method is to create a linestring object between your test point and the points in the table (till we get a distance function)

select glength(geomfromtext(concat('linestring(0 0, ', x(node), ' ', y(node), ')')))
from table

Where 0 0 is your test point.

Bit ugly but works ;-)
