perform query on GRASS vector layer?

[Wolfgang Qual]

Good morning, list.
I am desperately looking for a possibility to perform a query on my 
grass vector data. Attributes are stored in a sqlite3-database; the 
grass layer is integrated in the map via OGR.
Until now, I used shapefiles for displaying my vector data (and the 
query function is really necessary for me).
Really would appreciate any comments on this.

Best regards,

Wolfgang
