I am using QGIS 3.16.
I computed an Origin Destination Matrix for my studies using a total of 2478 (x13) routes. I then computed an SQL query in order to match each start point with its nearest end point. But this only computed 2458 routes (when it should have computed 2478).
Does anyone know why this is the case or what may have happened?
My SQL input is below. The algorhitm's ran smoothly and no error messages appeared, so I'm not quite sure why it cut layers out.
