当我尝试在属性多对一中插入属性insert = true的新实体时出现问题。 一旦事务提交我就会收到错误（此SqlParameterCollection的索引N无效，Count = N） 与映射文件commandeclient.hbm.xml发生的情况 并且对于Adresselivraisonclient.hbm.xml，即使使用insert = true
也很好问题是我在Adresselivraisonclient.hbm.xml上有复合键，这个表与commandeclient.hbm.xml有关，其中两个表都包含[client]列。
有没有改变名称的任何解决方案？
这里有2个地图文件。

答案 0 :(得分：0)
问题主要发生在列映射到多个属性上。 在这种情况下，我认为问题出在[piece]列中。
您正在使用它作为ID和集合的关键
<id name="Piece" column="[piece]" type="Int32" >
<generator class="assigned" />
</id>
<bag name="LignecommandeclientList" inverse="true" cascade="all-delete-orphan" lazy="true" >
<key>
<column name="[piece]" />
</key>
<one-to-many class="Lignecommandeclient" />
</bag>
在一个包中，默认密钥是实体ID，因此您可以尝试从包中删除密钥节点。
<bag name="LignecommandeclientList" inverse="true" cascade="all-delete-orphan" lazy="true" >
<one-to-many class="Lignecommandeclient" />
</bag>
