Question

尝试为Order实体执行HQL批量更新时，我遇到以下异常：

   Specified method is not supported.

   at NHibernate.Hql.Ast.ANTLR.PolymorphicQuerySourceDetector.Process(IASTNode tree)

   at ...Repositories.OrderRepository.MarkAsConfirmed(IEnumerable`1 orderIds) in C:\Users\Miroslav\Documents\Projects\...\OrderRepository.cs:line 40
   at ConfirmationUploadTask.Execute()

请注意，订单实体已映射到订单表，因此不应是任何与保留关键字相关的问题。其他基于LINQ 2 NHibernate的查询正常工作。当使用其他映射实体而不是Order时，查询可以正常工作。

我也试过了hbm2ddl.keywords=auto-quote as mentioned by Fabio，但没有运气。

作为参考，这是查询的样子：

var query = GetSession().CreateQuery(
    "update Order set IsConfirmed = :isConfirmed where id in (:ids)");

当使用CreateSQLQuery时，它可以正常工作：

var query = GetSession().CreateSQLQuery(
    "UPDATE Orders SET IsConfirmed = :isConfirmed WHERE OrderId in (:ids)");

有什么想法吗？

我认为这是一个错误;请在http://jira.nhforge.org

作为解决方法，限定Order实体的名称。例如：

update MyProj.Domain.Order set IsConfirmed = :isConfirmed where id in (:ids)

NHibernate HQL批量更新失败，“指定的方法不受支持”异常
