One problem I've seen with enums is that I end up with a blank ('') field 
if I try to insert a row with a value in the enum column that doesn't fit.

Is there a way to get the insert to fail on "bad input" instead?

For example:

mysql> CREATE TABLE Stats (
     ->   Status enum('good','bad') NOT NULL
     -> );
Query OK, 0 rows affected (0.00 sec)

mysql> INSERT INTO Stats VALUES ('neither');
Query OK, 1 row affected (0.00 sec)

(Can I get this insert to FAIL instead? because...)

mysql> select * FROM Stats;
+--------+
| Status |
+--------+
|        |
+--------+
1 row in set (0.01 sec)

(this isn't always a good thing).
