Yes we should implement a cheat in QGIS (core) to handle this issue. Other SQLite GUIs do this. Spatialite GUI and SQLite Manager (Firefox plugin).
The basic process: 1. Make a new table the way you actually want it. 2. SQL INSERT records from Old to New (Mapping old columns to new if name changed). 3. Remove old table 4. Rename new table to old name 5. Vacuum to recover extra pages allocated in the shuffle. Nothing else should be needed, since you use the same name, spatial indexes and geometry_column records should stay the same unless the Geometry column is renamed. This method will apply to both GeoPackage (If editing is allowed), Spatialite tables, and any non-spatial sqlite tables. -Alex On 11/12/2015 04:30 AM, Matthias Kuhn wrote: > The main issues with spatialite are IMO: It's based on sqlite so > deleting columns and renaming columns is not supported by design.
