如何使用Sqlite.Net扩展过滤器

Question

我正在使用Sqlite.Net Extensions库从我的数据库中获取对象。

我有一个Id's的列表，我想从我的列表中包含该Id的数据库中获取所有对象。

我有以下几点：

var filteredCalls = listOfIds;    
var conn = Databsae.Connection; 
var NewCalls = conn.GetAllWithChildren<Call>(x => filteredCalls.Any(y => y == x.Id)); 

但这代码返回错误：

[ERROR] FATAL UNHANDLED EXCEPTION: System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.NotSupportedException: Cannot compile: Lambda 08-30 15:46:57.210 E/mono-rt (16849): at SQLite.Net.TableQuery 1[T].CompileExpr (System.Linq.Expressions.Expression expr, System.Collections.Generic.List 1 queryArgs) [0x007aa] in :0 08-30 15:46:57.210 E/mono-rt (16849): at SQLite.Net.TableQuery 1[T].CompileExpr (System.Linq.Expressions.Expression expr, System.Collections.Generic.List 1 queryArgs) [0x001a5] in :0 08-30 15:46:57.210 E/mono-rt (16849): at SQLite.Net.TableQuery 1[T].GenerateCommand (System.String selectionList) [0x0006d] in <filename unknown>:0 08-30 15:46:57.210 E/mono-rt (16849): at SQLite.Net.TableQuery 1[T].GetEnumerator() [0x00008] in :0 08-30 15:46:57.210 E/mono-rt (16849): at System.Collections.Generic.List 1[T]..ctor (IEnumerable 1 collection) [0x00073] in /Users/builder/data/lanes/3540/1cf254db/source/mono/external/referencesource/mscorlib/system/collections/generic/list.cs:98 08-30 15:46:57.210 E/mono-rt (16849): at System.Linq.Enumerable.ToList[TSource] (IEnumerable 1 source) [0x00011] in /Users/builder/data/lanes/3540/1cf254db/source/mono/external/referencesource/System.Core/System/Linq/Enumerable.cs:835 08-30 15:46:57.210 E/mono-rt (16849): at SQLiteNetExtensions.Extensions.ReadOperations.GetAllWithChildren[T] (SQLite.Net.SQLiteConnection conn, System.Linq.Expressions.Expression 1 filter, Boolean recursive) [0x00015] in /Users/redent/Documents/workspace/sqlite-net-extensions/SQLiteNetExtensions/Extensions/ReadOperations.cs:60

所以我怎么使用GetAllWithChildren方法没有它崩溃？该文档是很稀疏

额外

这是说here如果是这样的情况下，line where the method is implemented

可能lambda表达式不能在SQLite的支持，什么是另类/怎么了这种方法应该使用？

Answer 1

所以看起来好像Sqlite.Net无法应对嵌套在另一个lamdba表达式中的Lambda表达式。因此，我将我的过滤器更改为：

var NewCalls = conn.GetAllWithChildren<DiaryCall>(x => filteredCalls.Contains(x.Id));
