Either the data you are inserting into Column2 is different between the two runs (trailing spaces, perhaps?) or you are inserting into different database files. After the database is filled with allegedly duplicate data, what do the following queries return? select count(*) from TestDB; select count(*) from (select 1 from TestDB group by Column2 having count(*) > 1); Igor Tandetnik _______________________________________________ sqlite-users mailing list sqlite-users@sqlite.org http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-users
