I'm not sure why you see a difference of behaviour between the 2 syntax.
Perhaps it is due to the way the primary key has been defined. It might be that
when given by layer name, OGR detects the primary key column, whereas it
doesn't when passed with -sql. Could you paste the schema of the table ?
Otherwise, FID are special columns in OGR. If you want to preserve them with
ogr2ogr, you need to add the -preserve_fid option in the ogr2ogr command line.
