Re: [Qgis-user] Spatial Query with buffer?
What's your data source? If it's PostGIS a query could do that in a mostly straightforward way.

Re: [Qgis-user] Spatial Query with buffer?
Ah! Good point! I forgot that spatialite can handle complex queries. For reference, Jorish, spatialite is a sqlite database with geospatial support. Sqlite is a (really super cool) library that supports single file databases that can be queried via SQL.

If you don't have an easy way to set up PostGIS, you could use QGIS to save your data in a SpatiaLite database, and then write a spatial query against that.
