使用 session.Delete 获取错误：“无法执行查询”。

当我复制查询并在 SQL Server Management Studio 中运行它时，选择查询运行没有问题。似乎问题出在删除或其他东西上……我使用相同的方法从其他表中删除了记录，并且似乎工作正常。

任何想法是什么原因造成的？

班上：

    public class MultisitePublicBooking
    {
        public virtual int Id { get; set; }
        public virtual int multisiteID { get; set; }
        public virtual DateTime startDate { get; set; }
        public virtual DateTime startTime { get; set; }
    }

    public MultisitePublicBookingMap()
    {
        Table("tblMultisitePublicBooking");

        Id(x => x.Id).Column("PublicBookingID");
        Map(x => x.multisiteID).Column("MultisiteID");
        Map(x => x.startDate).Column("StartDate");
        Map(x => x.startTime).Column("StartTime");

    }

表如下：

CREATE TABLE [dbo].[tblMultisitePublicBooking](
[PublicBookingID] [int] IDENTITY(1,1) NOT NULL,
[MultisiteID] [int] NULL,
[NumAttendees] [int] NULL,
[AttendeeName] [varchar](1024) NULL,

从 TimeSpan 到 SQL“时间”数据类型的映射似乎存在一些问题。

您可以通过像这样设置 startTime-property-mapping 来修复它：

        Map(x => x.startTime).CustomType("TimeAsTimeSpan");

正确设置映射后，您还可以删除指定的记录。

你是对的，问题出在sql server时间列映射中。你可以在这里阅读更多：这里

xml文件中的映射如下所示：

<property name="StartTime" type="TimeAsTimeSpan" />

实体将是：

public class MultisitePublicBooking
{
    public virtual int Id { get; set; }
    public virtual int MultisiteID { get; set; }
    public virtual DateTime StartDate { get; set; }
    public virtual TimeSpan StartTime { get; set; }
}
