New description:

When trying to save a multipolygon shapefile to Spatialite using the "save as" dialog the operation fails. Actually the fail is by ogr2ogr. When using ogr2ogr from the command line it is enough to add

-nlt MULITPOLYGON

option, but in the "save as" dialog is not clear if such option can be added in the "custom options" of the same dialog.

The real issue seems that QGIS is not consistent, in fact importing into a Spatialite DB works fine for multigeometry input layers both using the Drag and Drop from the QGIS browser and using the import function of DB manager.

It also works ok using the "convert format" tool (based on ogr2ogr) of the processing toolbox (without needed to add manually any parameter).

It is not clear to me how that step made into the documentation as the very same issue affects QGIS down to 1.8 included (maybe in an earlier release it was ok).

Old Description:

On page 7 of the QGIS Training Manual, users are instructed to save the landuse layer as SpatialLite. In so doing, the following error was encountered, using the dataset as described in the training manual.

Export to vector file failed.
Error: Feature write errors:
Feature creation error (OGR error: sqlite3_step() failed:
landuse.GEOMETRY violates Geometry constraint [geom-type or SRID not allowed] (19))
Only 52 of 53 features written.

A file is created in the directory, but nothing is added to the map
