MySQL error

I am writing a custom module with several database-tables. When writing content to a new table I get this error message for which I cannot detect what is wrong.
The message is:
user warning: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'order (oid, uid, aangetekend, verzekerd, orderdatum, bestelinfo) VALUES (29, 5, ' at line 1 query: INSERT INTO order (oid, uid, aangetekend, verzekerd, orderdatum, bestelinfo) VALUES (29, 5, 0, 0, 1259938004, '') in /var/www/html/includes/database.mysql.inc on line 174.

When I paste: INSERT INTO `order` (`oid`, `uid`, `aangetekend`, `verzekerd`, `orderdatum`, `bestelinfo`) VALUES (29, 5, 0, 0, 1259938004, '')
in the query-SQL-box of MySQL the record is inserted in the database.

What is wrong in my setup/code?

The code is:
db_query("INSERT INTO {order} (oid, uid, aangetekend, verzekerd, orderdatum, bestelinfo) VALUES (%d, %d, %d, %d, %d, '%s')", $ordernr, $user->uid, ($klant['aangetekend_order'] ? 1 : 0), ($edit['verzekerd'] ? 1 : 0), time(), $edit['extra']);

The database dump is:
