Hi, I'm using QGIS 2.0.1 on Windows 7.
I'm trying to join a .dbf which contains no spatial data to a shape file containing spatial data. Ideally I'd like to create an attribute index on the join field in the .dbf before I join it to the shape file. Does anybody know how I can do this? Also in the join menu there are two tick box options: 1. Cache join layer in virtual memory 2. Create attribute index on join field Can anybody tell me what these two options mean? Is the attribute index created during the join if I was to tick this or is it done before the join?
