SQL Window Functions is the number one feature that I could use as well. In R, sqlite can be used for manipulating R data frames via the sqldf package and this sort of functionality would be very useful. (sqldf also handles PostgreSQL which does have windowing functions but PostgreSQL requires more set up than sqlite so its not as accessible to users.) _______________________________________________ sqlite-users mailing list sqlite-users@sqlite.org http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-users
