Yes, this is exactly the same issue I encounter. There are 2 rows in the result with Spatialite GUI, but only one with System.Data.Sqlite.

Simplified for plain ol' SQLite as follows: CREATE TABLE L (Lid INTEGER PRIMARY KEY); INSERT INTO L VALUES(1); CREATE TABLE P (Pid INTEGER PRIMARY KEY, Lid INTEGER); INSERT INTO P VALUES(1,1); INSERT INTO P VALUES(2,1); CREATE VIRTUAL TABLE R USING rtree(Pid, xmin, xmax); INSERT INTO R VALUES(1,0,0); INSERT INTO R VALUES(2,0,0); CREATE INDEX idx_P_Lid ON P (Lid); -- fails, result should be two rows: SELECT * FROM P JOIN L USING (Lid) JOIN R USING (Pid) WHERE L.Lid = 1; Regards, Clemens _______________________________________________ sqlite-users mailing list sqlite-users@sqlite.org http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-users _______________________________________________ sqlite-users mailing list sqlite-users@sqlite.org http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-users
