c# - 执行多条件时出错，未知列 - Mono + NHibernate + MySQL

Question

在apache + mod_mono + mysql下运行ASP.NET MVC应用程序 我收到此错误:

MySql.Data.MySqlClient.MySqlException
Unknown column 'this_.date_created' in 'field list'

异常(exception):

NHibernate.HibernateException: Error executing multi criteria : [SELECT count(*) as y0_ FROM tag this_;
SELECT this_.id as id4_0_, this_.name as name4_0_, this_.description as descript3_4_0_, this_.date_created as date4_4_0_, this_.total_peruns as total5_4_0_, this_.user_id as user6_4_0_ FROM tag this_ ORDER BY this_.total_peruns desc limit ?p0;

    ...

该表中存在 date_created 列。

相同的应用程序可以在我的带有 Windows 版本 mysql 的 Windows 开发机器上运行。

MySQL Linux: 5.5.34

MySQL Windows: 5.6.12

nHibernate version: 3.1.0.4000

生成的 SQL 在数据库中正确执行 (?p0 = 10):

SELECT this_.id as id4_0_, this_.name as name4_0_, this_.description as descript3_4_0_, this_.date_created as date4_4_0_, this_.total_peruns as total5_4_0_, this_.user_id as user6_4_0_ FROM tag this_ ORDER BY this_.total_peruns desc limit ?p0;

什么可能导致此问题？

Answer 1

这种事每个人都会遇到。环境、库或 MySQL 都没有问题。 我的连接字符串指向旧版本的数据库。 Web.config

  <connectionStrings>
   <add name="localhost" connectionString="Server=name;Database=old_database_version;User id=user;Password=pass;"/>   
  </connectionStrings>

感谢大家的努力和时间。
