Hi
I have an expression such as -
select ST_distance(st_centroid(p_id.p_id.the_geom),
st_boundary(p_id.p_id.the_geom))/2 + 15000
from p_id.p_id
where p_id.p_id.process_id = '1012' ;
This works
I can access the number 15000 from a table as a variable.
I want to be able to also access the + (or -) from a table as a variable but
can't figure out how to do this.
Is it possible to store math operators and access them from a table??
Bob
