Question

我使用Fluent NHibernate映射带有复合键的表。我想问一下是否有人知道未保存的DateTime的值应该是多少。我写了＃34; XXXXXXXX＆＃34;在代码示例中应插入默认值。

我现在可以看到您只能设置一次未保存的值。如果为每个键设置它，则在Fluent创建hbm.xml文件时会出现错误。所以我们需要在一个字符串中指定两个键值。

后端是Oracle，我正在映射到Date。

internal class BondRawAccruedDataMap : ClassMap<BondRawAccruedData>
{
    public BondRawAccruedDataMap()
    {
        Schema("fpd");
        Table("bond_accrued_raw_data");

        CompositeId().KeyProperty(x => x.Instrument, "instrument").UnsavedValue("0")
                     .KeyProperty(x => x.RunDate, "run_date").UnsavedValue(DateTime.MinValue.ToString(XXXXXXXXXXXX));
        Map(x => x.SettleDate, "settle_date");
        Map(x => x.AccruedInterest, "accrued_interest");
        Map(x => x.AccruedFactor, "accrued_factor");
        Map(x => x.PrincipalFactor, "principal_factor"); 
        Map(x => x.InterestDaysSinceCoupon, "days_acc");
    }
}

更新了映射

internal class BondRawAccruedDataMap : ClassMap<BondRawAccruedData>
{
    public BondRawAccruedDataMap()
    {
        Schema("fpd");
        Table("bond_accrued_raw_data");

        CompositeId().KeyProperty(x => x.Instrument, "instrument")
                     .KeyProperty(x => x.RunDate, "run_date").UnsavedValue("Unsaved value for instrument and rundate");
        Map(x => x.SettleDate, "settle_date");
        Map(x => x.AccruedInterest, "accrued_interest");
        Map(x => x.AccruedFactor, "accrued_factor");
        Map(x => x.PrincipalFactor, "principal_factor"); 
        Map(x => x.InterestDaysSinceCoupon, "days_acc");
    }
}
