sorry for the first select (bad copy of a string 'lastname'):
mysql> select concat(firstname,' ',lastname) from names where concat(firstname,'
',lastname) like 'Jean Dupond%';
+--------------------------------+
| concat(firstname,' ',lastname) |
+--------------------------------+
| Jean Dupond                    |
+--------------------------------+
1 row in set (0.00 sec)
