Something is wrong with your logic or programming. Having this index should make a huge difference in the speed of lookup. How are you finding the entries in the TABLE called 'data' ? Actually, as Jan posted, instead of the above index do this one: CREATE UNIQUE INDEX dfdv ON data (file_id,data_type, value) Simon. _______________________________________________ sqlite-users mailing list sqlite-users@sqlite.org http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-users
