I was playing with indexes, I started checking one my queries with EXPLAIN QUERY PLAN and I got this result: selectid order from detail ---------- ---------- ---------- --------------------------------------------------------------------- 0 0 1 SEARCH TABLE tour AS t2 USING INTEGER PRIMARY KEY (rowid=?) (~1 rows) 0 1 0 SCAN TABLE tour AS t1 (~5000 rows)
Adding an index on the column unsorted_path it becomes: selectid order from detail ---------- ---------- ---------- --------------------------------------------------------------------- 0 0 1 SEARCH TABLE tour AS t2 USING INTEGER PRIMARY KEY (rowid=?) (~1 rows) 0 1 0 SEARCH TABLE tour AS t1 USING INDEX t (unsorted_path=?) (~2 rows) And it seems quite an improvement, alas now I get this error: "cannot open indexed column for writing." What does it mean? _______________________________________________ sqlite-users mailing list sqlite-users@sqlite.org http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-users
