I have two layer (lineshapes from OSM) with the same attributenames. But one of the layer includes more datasets. Now I want to create a query that compares both attributetables and put out/ select only the unequal datasets. So i want to get a atributetable with all the datesets, which not included in both shapes.
But i don't know how to do it, because the atributename in both layer are the same.
for example: the first atributetable includes 110000 datasets. the second atributetable includes 130000 datasets.
So i want two compare the atribute "osm_id" in both layer. the result should be all osm_id's which just include in one of the layer.
