我对这段代码有错误，我不知道为什么。

我的代码由两个文件组成：

  1. systemprop.cs
  2. System.hbm.xml

但我有以下错误：

Erreur de syntaxe près de '[propertyID] as column1_19_, systemprop0_.[value] as column2_19_, systemprop0_.[' à la ligne 1"

这意味着我'[propertyID] as column1_19_, systemprop0_.[value] as column2_19_, systemprop0_.['在第 1 行附近有一个语法错误。

这是我的代码：

类Systemprop： 

using System;
using System.Collections.Generic;
using System.Text;
using NHibernate;
using DATA;

namespace DATA
{
    public partial class Systemprop
    {
        private string PropertyID  { set; get; }
        private string Value        { set; get; }
        private string Description   { set; get; }
        private int LastUpdateTime     { set; get; }
        private int CreationTime    { set; get; }
        // public Systemprop() { }

        public static ISessionFactory SessionFactory;
        public static ISession OpenSession()
        {
            if (SessionFactory == null)
            {
                Configuration config = new Configuration();
                config.SetProperty(NHibernate.Cfg.Environment.ConnectionProvider, "NHibernate.Connection.DriverConnectionProvider");
                config.SetProperty(NHibernate.Cfg.Environment.Dialect, "NHibernate.Dialect.MySQLDialect");
                config.SetProperty(NHibernate.Cfg.Environment.ConnectionDriver, "NHibernate.Driver.MySqlDataDriver");

                config.SetProperty(NHibernate.Cfg.Environment.ConnectionString, "Server=localhost;Database=opengts;Uid=root;Pwd=;");
                config.AddAssembly("DATA");

                SessionFactory = config.BuildSessionFactory();
            }
            return SessionFactory.OpenSession();
        }
        public static IList<Systemprop> GetSystemprop()
        {
            using (ISession session = OpenSession())
            {
                if (session != null)
                {
                    IQuery query = session.CreateQuery("FROM Systemprop");
                    IList<Systemprop> pets = query.List<Systemprop>();
                    return pets;
                }
            }

            return null;    
        }
    }
}

Systemprop.hbm.xml：

<?xml version="1.0" encoding="utf-8" ?>
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" namespace="DATA" assembly="DATA">
    <class name="Systemprop" table="[dbo].[systemprops]" >
        <id name="PropertyID" column="[propertyID]" type="String" length="32" >
            <generator class="assigned" />
        </id>
        <property name="Value" column="[value]" type="String" not-null="false" length="16" /> 
        <property name="Description" column="[description]" type="String" not-null="false" length="128" /> 
        <property name="LastUpdateTime" column="[lastUpdateTime]" type="Int32" not-null="false" /> 
        <property name="CreationTime" column="[creationTime]" type="Int32" not-null="false" /> 
    </class>
</hibernate-mapping>

但我有这个错误：

dbo从映射文档中取出所有括号和。只需使用表名和列名，就像在数据库中输入它们一样。然后试一试。
