NHibernate.Exceptions.GenericADOException：“无法执行批处理命令。[SQL：SQL不可用]”

Question

当我按照官方教程一步一步地运行应用程序时，错误即将到来。

NHibernate.Exceptions.GenericADOException:“could not execute batch command.[SQL: SQL not available]”
SqlException: Conversion failed when converting the nvarchar value '44a0efdef8b648dba4c6a4c67378b7ed' to data type int.

错误区域

ISession session = NHibernateHelper.GetCurrentSession();
        try
        {
            using (ITransaction tx = session.BeginTransaction())
            {
                myTable princess = new myTable();
                princess.Id = "10";
                princess.Name = "test";
                princess.Sex = "man";
                princess.Sal = 1.1f;
                session.Save(princess);
                tx.Commit();//error is here
            }
        }
        finally
        {
            NHibernateHelper.CloseSession();
        }

这是我的映射文件：

<?xml version="1.0" encoding="utf-8" ?>
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2"
namespace="getFromMS" assembly="getFromMS">
<class name="getFromMS.Models.myTable" table="myTable">
<id name="Id">
  <column name="Id" sql-type="int" not-null="true"/>
  <generator class="uuid.hex" />
</id>
<property name="Name">
  <column name="Name" length="50" not-null="true" />
</property>
<property name="Sex">
  <column name="Sex"  length="10" not-null="true" />
</property>
<property name="Sal">
  <column name="Sal" sql-type="float" not-null="true"/>
</property>
</class>
</hibernate-mapping>

出厂配置：

    <configSections>
    <section name="hibernate-configuration" type="NHibernate.Cfg.ConfigurationSectionHandler, NHibernate" />
    </configSections>
    <hibernate-configuration xmlns="urn:nhibernate-configuration-2.2">

    </property>
    <mapping assembly="getFromMS" />
    </session-factory>
    </hibernate-configuration>

班级：

    public class myTable
    {
        public virtual string Id { set; get; }
        public virtual string Name { set; get; }
        public virtual string Sex { set; get; }
        public virtual float Sal { set; get; }
    }
