Thank you for your thoughts but I already tried this with no different results than before. And according to http://www.sqlite.org/optoverview.html#between_opt this is exactly what happens behind the curtains when SQLite processes BETWEEN statements. What I'm actually looking for is a way to make SQLite create and consider histogram data for rowid lookup the same way as for regular indexes. regards gerd _______________________________________________ sqlite-users mailing list sqlite-users@sqlite.org http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-users
