使用Orchard HQL API将非ContentPart表加入ContentPart表

Question

我正尝试使用Orchard HQL API在两个不同表之间进行简单连接。问题是其中一个表不是ContentPartTable。这可能吗？？

下面是它看起来像在普通的SQL：

Select * From ItemPartRecord 
Join ItemRecord 
On ItemRecord.ItemId = ItemPartRecord.ItemId 
Where ItemRecord.Price Between 1000 and 10000 

我究竟怎么会去这样做呢？

如果你想知道如何做到这一点：

//Join the non content part table 
var defaultHqlQuery = query as DefaultHqlQuery; 
var fiJoins = typeof(DefaultHqlQuery).GetField("_joins", BindingFlags.Instance | BindingFlags.NonPublic); 
var joins = fiJoins.GetValue(defaultHqlQuery) as List<Tuple<IAlias, Join>>; 
joins.Add(new Tuple<IAlias, Join>(new Alias("ExampleNamespace.Data.Models"), new Join("ExampleRecord", "ExampleAlias", ","))); 
Action<IHqlExpressionFactory> joinOn = predicate => predicate.EqProperty("valueToJoinOn", "aliasToJoinOn.valueToJoinOn"); 
query = query.Where(
alias => alias.Named("ExampleAlias"), 
joinOn 
);
