[GRASS-dev] trying to update column with another text column

I want to update a column with the value of another column. I am using v.db.update. The docs say that I can update a column with the value of another column by specifying that column in the value field. In fact, if I put the names of numeric columns, this works fine (e.g., v.db.update

Hi Pietro, this is an interesting and very useful submission. A numpy matrix interface would be a valuable addition, but as Markus Metz said, we need also direct row access without reading the whole raster or vector map into the memory. Actually with the vtk-grass-bridge there is already an
