Question

在 apache + mod_mono + mysql 下运行ASP.NET MVC应用程序我收到这个错误：

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

例外：

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;

    ...

该表中的date_created列存在。

相同的应用程序在我的Windows开发机器上使用windows版本的mysql。

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;

可能导致此问题的原因是什么？

这件事发生在每个人身上。环境，库或MySQL没有错。我的连接字符串指向旧版本的数据库。的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。

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