I have a complex workflow prepared in the processing modeler, but I'm missing one step to link all the model.
As said, I need to dissolve a polyline vector in a single line vector that has as attribute the SUM of a specified attribute of the polyline vector.I can do it via plugin (dissolve with stats) but just outside the modeler, I tried to find a way to link the "dissolve" tool and the "basic statistics for numeric field" tool but I still can't figure out how to put the html output inside the vector layer.
I saw some comments about an sql query that looks easy, but I don't know if I can use it outside spatialite or sql, inside the modeller.
