I joined a sqlite layer with a csv table (each attribute field name starts with a capital letter). When I create a new layer out of them ("save as", e.g. as a new sqlite layer with all data combined), the attribute field names in the new layer are changed to lower case. The entries in the table are not affected, though - only the attribute field names (= column title, to say it differently).
Does anyone have an idea how I can save a join of a spatialite layer and csv table and at the same time keep the original attribute field name that is case-sensitive? I also tried to use a different codification, but this did not help.
