任何条件的Nhibernate查询

Question

我有像

这样的表结构

Product {List<Cost> Costs}

Cost{List<Invoice> Invoices, Product product}

Invoice{bool isIncluded}

需要查询才能获得所有包含任何发票费用的产品（isIncluded = false）

我尝试过类似的事情：

Product pro= null;
Product p = null;

        var costQuery = QueryOver.Of<Cost>()
            .JoinAlias(c => c.Product, () => p)
            .Where(() => p.Id == pro.Id)                
            .WhereNot(c=>c.Invoices.Any(i=>i.IsIncluded))
            .Select(c => c.Id);

        var query = CurrentSession.QueryOver<Product>(() => pro)                
                                  .WithSubquery.WhereExists(costQuery);

在查询错误中使用“任何”：

  

无法识别的方法调用：System.Linq.Enumerable：Boolean   任何[发票]（System.Collections.Generic.IEnumerable 1[Trigger.StageGate.Services‌​.BusinessEntities.Invoice], System.Func 2 [Trigger.StageGate.Services.BusinessEntities.Invoice，System.Boolean]）

Answer 1

尝试：

var costQuery = QueryOver.Of<Cost>()
        .JoinAlias(c => c.Product, () => p)
        .Where(() => p.Id == pro.Id)            
        .JoinQueryOver<Invoice>(c => c.Invoices)
        .WhereNot(i => i.IsIncluded)    
        .Select(c => c.Id);
