It's bad solution:
sqlite> CREATE TABLE T1 (N INTEGER CHECK(+N >= 0));
sqlite> INSERT INTO T1 VALUES('-5');
sqlite> INSERT INTO T1 VALUES('q');
sqlite> select N, typeof(N) from T1;
-5|integer
q|text-- Best regards, Alexey Pechnikov. http://pechnikov.tel/ _______________________________________________ sqlite-users mailing list sqlite-users@sqlite.org http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-users
