These are not working because MySQL is interpreting the database names as expressions. Look closely at the db names: 3208e+1 208e+1 08e+1 8e+1 > mysql> create database e1c6aa32; > Query OK, 1 row affected (0.01 sec) This works fine. Suggestion: Don't use database names starting with integers unless you use back ticks. This will work for you: mysql> create database `3208e1c6aa32`; Though I would recommend not using such names. Some poor guy working on your application six months down the line is going to wonder why his queries are failing, spend a day trying to figure out and will post the same question again to this list :-) Cheers!
