The following code exports data from the OGRExportTable in the localhost\\sqlexpress SQL Server instance to an ESRI Shapefile called c: emp\\sqlexport_linestring.shp . ESRI Shapefiles can only contain features of a single geometry type.

Which is the command line tool for ogr2ogr?

ogrinfo – inspects a GIS datasource and spits out summary data or detailed information about the layers, kinds of geometries found in the file. ogr2ogr – this is a command line tool that converts one Ogr defined data source to another Ogr data source.
