GenericADOException: Failed to insert

I am trying to store an order object in a database that is many-to-one related to the pastaIndividual table.

But I get this exception:

Error: NHibernate.Exceptions.GenericADOException: Failed to insert: [FrancosPoS.DBMapping.order] [SQL: INSERT INTO order (price, cash, credit, obs) VALUES (?,?,?,?); SELECT LAST_INSERT_ID ()] ---> MySql.Data.MySqlClient.MySqlException: You have an error in your SQL syntax; check the manual that matches the version of your MySQL server. for the correct syntax to use near order (price, cash, credit, obs) VALUES ('123', 1, 0, 'Nhibernate'); SELECT LAST_ 'on line 1

Here is my order mapping table:

<?xml version="1.0" encoding="utf-8"?>
<hibernate-mapping assembly="FrancosPoS" namespace="FrancosPoS.DBMapping" xmlns="urn:nhibernate-mapping-2.2">

    </id>
    <set name="pastaIndividual" table="pasta_individual" cascade="save-update">
      <key column="idPastaI"/>
      <one-to-many class="pastaIndividual"/>
    </set>
    <!--<many-to-one insert="false" update="false" lazy="false" name="pastaIndividual" class="FrancosPoS.DBMapping.pastaIndividual">

    <property name="obs">
      <column name="obs" sql-type="varchar(150)" not-null="false" />
    </property>
  </class>
</hibernate-mapping>

Here is my past individual display:

<?xml version="1.0" encoding="utf-8"?>
