Linq查询不返回结果，但是查询正常

Question

我的应用程序中有一个Linq查询，看起来像

claim[] claimLst = (from clms in dbContext.claims where 
                                 clms.@switch == 8
                            && (clms.Status == "Received Ok" || clms.Auto_Resubmit == 1)
                            && ((short)clms.tiMarkedForSubmission_M == 0 
                               || (short)clms.tiMarkedForSubmission_T == 0)
                            select clms).ToArray();

当我在SQL Server Profiler中查看它时，我可以看到它已解析为

exec sp_executesql N'SELECT [t0].[id], [t0].[datetime_received], 
[t0].[Uniqueid], [t0].[Practice_number], [t0].[regnum], [t0].[claim_number], 
[t0].[Status], 
[t0].[Date_time], [t0].[Action], [t0].[Med_resp], [t0].[Tar_resp], [t0].[switch],
[t0].[Auto_Resubmit], [t0].[Auto_Resubmit_Count], 
[t0].[tiMarkedForSubmission_M], [t0].[tiMarkedForSubmission_T]
FROM [dbo].[claims] AS [t0]
WHERE ([t0].[switch] = @p0) AND (([t0].[Status] = @p1) OR ([t0].[Auto_Resubmit] = @p2)) 
AND ((([t0].[tiMarkedForSubmission_M]) = @p3)
OR (([t0].[tiMarkedForSubmission_T]) = @p4))'
,N'@p0 int,@p1 varchar(8000),@p2 int,@p3 int,@p4 int',
@p0=8,@p1='Received Ok',@p2=1,@p3=0,@p4=0

当我运行这个sql时，我没有得到任何结果。 我在运行查询时的位置

Select * from dbo.claims clms where 
                  clms.switch = 8 AND 
                 (clms.Status = 'Received Ok' 
                  OR clms.Auto_Resubmit = 1)
                  AND (clms.tiMarkedForSubmission_M = 0 
                 OR clms.tiMarkedForSubmission_T = 0)

我得到10条记录。

两个查询有什么不同，1给我结果而另一个没有？
