Problem with database on iOS device

Hi, I need some help with titanium.datatabase.install.

I'm having problem with database on iOS device. When I pass de app to device and try to run on, error appear with the next message:

invalid database install path. /var/mobile/Applications/AF3ED534-B983-48EC-926C-84C456200AA7/Ejercicio1.app/UsuariosDB.sql in -[TiDatabaseProxy install:name:] (TiDatabaseProxy.m:145) at app.js (line 1)

Here's my code:

var db = Titanium.Database.install('UsuariosDB.sql','UsuariosDB');

Thanks for helps.
