comment How to draw a line between two places with via-points?
thanks a lot, but i do not understand your answer. my problem is, that the raw points (via points) are not grouped and that they lie in an other table as the start and arrival points. The table with the stopping points give me the lowest and the highest id of the points, that have to build the line-segments between the stoppng points...
