C# BLToolKit生成错误的SQL

我使用BLToolKit作为ORM映射器

我的问题是，它生成了错误的SQL

我有一个疑问：

var qry = from i in s.Query<ChannelDTO>() 
            join o in s.Query<StorageShelfDTO>() on i.Id equals o.ChannelID into p1
            select new {i.Id, n = p1.Count()};

        var qry2 = qry;
        qry2 = qry2.Where(x => x.n == 0);
        Debug.Print("Entrys: " + qry2.ToList().ToString());

缺少外部选择中的计数字段

但当我取消条件时：

 qry2 = qry2.Where(x => x.n == 0);

然后生成正确的SQL。

生成的查询是正确的

您有您的初始linq声明：

var qry = from i in s.Query<ChannelDTO>() 
            join o in s.Query<StorageShelfDTO>() on i.Id equals o.ChannelID into p1
            select new {i.Id, n = p1.Count()};

现在，当您将第二部分添加到查询（qry2）中时，这将添加到原始查询中，因为它使用的是延迟执行。因此，最终生成的查询在执行时如下所示：

var finalQuery = (from i in s.Query<ChannelDTO>() 
                 join o in s.Query<StorageShelfDTO>() on i.Id equals o.ChannelID into p1
                 select new {i.Id, n = p1.Count()}).Where(x => x.n == 0)

我知道有德弗德死刑，这也是我想要的！但是外部选择缺少计数，因此结果中没有填充值！当i filter==0时可以，但是当i filter例如>0时，它也不会被填充

SELECT
    (
        SELECT
            Count(*)
        FROM
            [WMS_StorageShelf] [t1]
        WHERE
            [i].[ID] = [t1].[ChannelID]
    ) as [c1],
    [i].[ID] as [Id]
FROM
    [WMS_Channel] [i]

var finalQuery = (from i in s.Query<ChannelDTO>() 
                 join o in s.Query<StorageShelfDTO>() on i.Id equals o.ChannelID into p1
                 select new {i.Id, n = p1.Count()}).Where(x => x.n == 0)

var qry = (from i in s.Query<ChannelDTO>() 
            join o in s.Query<StorageShelfDTO>() on i.Id equals o.ChannelID into p1
            select new {i.Id, n = p1.Count()}).ToList();
