In GDAL 2.1.2 I was able to query from a GeoJSON data source using the following:

ogr2ogr -f geojson -dialect sqlite -sql "select * from OGRGeoJSON where NAME in ('Albania','Algeria')" countries.json world.json 

Whereas in GDAL 2.2.4 this results in the following error:

ERROR 1: In ExecuteSQL(): sqlite3_prepare_v2(select * from OGRGeoJSON where NAME in ('Albania','Algeria')):
  no such table: OGRGeoJSON

What's changed?

According to the GeoJSON documentation for GDAL 2.2:

Starting with GDAL 2.2, the layer name is built with the following logic:

If a "name" member is found at the FeatureCollection level, it is used. Otherwise if the filename is regular (ie not a URL with query parameters), then the filename without extension and path is used as the layer name. Otherwise OGRGeoJSON is used.

From this it seems the new syntax should be:

ogr2ogr -f geojson -dialect sqlite -sql "select * from world where NAME in ('Albania','Algeria')" countries.json world.json 
  • And there is no need to guess the name of the layer because you can check if with ogrinfo world.json. – user30184 May 7 '18 at 19:36
