One to many joins
Unable to export as WKT geometry
I'm trying to perform a one-to-many join between a postcode dataset (shapefile) and a csv txt dataset of addresses. I have multiple addresses per postcode, and need to be able to match all of them together.
I have seen various answers where I should export the Postcode dataset to a csv file and join together in LibreOffice etc. BUT when I try and "save as" there is no option for GEOMETRY AS_WKT ! only AS_XY etc.
