hi.
hope u can help me.
i want to workout crossover points on a graph.
the graph has multiple lines.
and the starting information is the points (pnt) values (x,y)
from this i want to create a second table that will hold the line segments. the sql must work out the line segments(Lseg) from the point values.
from this i would need to work out the crossover points, and wich lines are crossing over.
in addition to this i would like the databas eto shoe some robustness, in terms of y/x, when x=0. it should be able to to handle this.
thanx in advance for any help.
