sqlite in-memory databases

[Viktoras Didziulis]

Hi, 
 
does anyone know if after I create an in-RAM database using 
sqlite3 memory 
and then do for any stored database file: 
ATTACH db_file AS db_ram 
 
does it also load the attached database into RAM or continues to query the
attached database as it is (e.g. disk file) ? Any experiences with this?
 
Best wishes
