Question

在Nhibernate中导致这个1 = 0的原因

SELECT
        this_.LoanId as LoanId89_0_,
        this_.BranchId as BranchId89_0_, 
    FROM

    dbo.Loan this_ 
WHERE
    this_.LoanId in (
        SELECT
            this_0_.LoanId as y0_ 
        FROM
            dbo.MyEntity this_0_ 
        WHERE
            this_0_.MyEntityId = 795
    ) 
    and 1=0 
ORDER BY
    this_.LoanNumber asc;

我正在尝试检索一些记录，而Nhibernate在AND子句中将其转换为1 = 0

Loan.cs
    public Loan() : base()
        {
            this.Loanid = null; //int32 type
            this.Branchid = null; //int32 type
}

这是小版Loan Class的样子。由于子查询，它执行WHERE。它选择ID因为GetIQueryOverForLoanSearch.It只使用Projections和AliasToBean（SearchResult）选择所有列。我只是无法理解或弄清楚1 = 0的来源？还有一些子查询正在进行中。这只是一个非常小的版本

     var subQuery = QueryOver.Of<MyEntity>().Where(x => x.MyEntityId == entityId).Select(x => x.LoanId);
     var loans = GetIQueryOverForLoanSearch(manager.Session.GetISession(), false).WithSubquery.WhereProperty(x => x.Id).In(subQuery).OrderBy(x => x.LoanNumber).Asc.List<SearchResult>();

   private static IQueryOver<Loan, Loan> GetIQueryOverForLoanSearch(ISession session, bool setMaxSearchResults = true)
        {
            SearchResult lr = null;
            Loan l = null;

            var queryOver = session.QueryOver(() => l).Select(Projections.Property(() => l.Id).WithAlias(() => lr.LoanId)).TransformUsing(Transformers.AliasToBean<SearchResult>());

            return queryOver;
        }

我应该查看DataStructure或标准吗？

那是完整的代码吗？因为当空1 = 0存在时我看到悬空Restrictions.Disjunction，但我在那里看不到任何一个。

Nhibernate转换1 = 0
