GenericADOException:无法插入

Question

我试图将我的order对象保存在与表pastaIndividual有多对一关系的数据库中。

但是，我得到了一个例外：

错误: NHibernate.Exceptions.GenericADOException:无法插入: FrancosPoS.DBMapping.order --> MySql.Data.MySqlClient.MySqlException:您的SQL语法有错误；检查与MySQL服务器版本对应的手册，以获得使用接近“order(价格、现金、信用、obs)值”值('123‘、1、0、’Nhibernate‘)的正确语法；在第1行选择LAST_。

这是我的订单映射表：

<?xml version="1.0" encoding="utf-8"?>
<hibernate-mapping assembly="FrancosPoS" namespace="FrancosPoS.DBMapping" xmlns="urn:nhibernate-mapping-2.2">
  <class name="order" table="order" lazy="true" >
    <id name="idOrder">
      <generator class="identity" />
    </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">
      <column name="idPastaI" sql-type="int(11)" not-null="false" />
    </many-to-one>-->
    <many-to-one insert="false" update="false" lazy="false" name="pastaCombo" class="FrancosPoS.DBMapping.pastaCombo">
      <column name="idPastaC" sql-type="int(11)" not-null="false" />
    </many-to-one>
    <many-to-one insert="false" update="false" lazy="false" name="pastaFeast" class="FrancosPoS.DBMapping.pastaFeast">
      <column name="idPastaF" sql-type="int(11)" not-null="false" />
    </many-to-one>
    <many-to-one insert="false" update="false" lazy="false" name="salad" class="FrancosPoS.DBMapping.salad">
      <column name="idSalad" sql-type="int(11)" not-null="false" />
    </many-to-one>
    <many-to-one insert="false" update="false" lazy="false" name="drink" class="FrancosPoS.DBMapping.drink">
      <column name="idDrink" sql-type="int(11)" not-null="false" />
    </many-to-one>
    <property name="price">
      <column name="price" sql-type="decimal(8,4)" not-null="true" />
    </property>
    <property name="cash">
      <column name="cash" sql-type="tinyint(1)" not-null="false" />
    </property>
    <property name="credit">
      <column name="credit" sql-type="tinyint(1)" not-null="false" />
    </property>
    <property name="obs">
      <column name="obs" sql-type="varchar(150)" not-null="false" />
    </property>
  </class>
</hibernate-mapping>

下面是我的pastaIndividual映射：

<?xml version="1.0" encoding="utf-8"?>
<hibernate-mapping assembly="FrancosPoS" namespace="FrancosPoS.DBMapping" xmlns="urn:nhibernate-mapping-2.2">
  <class name="pastaIndividual" table="pasta_individual" lazy="true" >
    <id name="idPastaI">
      <generator class="identity" />
    </id>
    <property name="type">
      <column name="type" sql-type="varchar(25)" not-null="true" />
    </property>
    <property name="price">
      <column name="price" sql-type="decimal(8,4)" not-null="true" />
    </property>
  </class>
</hibernate-mapping>

我尝试过使用order映射来使用<set>或只使用<many-to-one>，但同样的错误也会发生。

也许我失去了一些逆属性？

谢谢。

秩序是一个保留的词。只需在类定义中添加一些回签，NHibernate就会自动为您转义表名。

 <class name="order" table="`order`" lazy="true" >
