今天早上在做一个新功能的时候发现了有一个bug.
跟踪的时候发现
Service Error: SQL 语句的某些部分嵌套过深。请重写查询或将其分解为若干较小的查询。. <!-- at System.Data.SqlClient.SqlConnection.OnError(SqlException exception, Boolean breakConnection)

看一下我们的linq语句
var query2 = ctx.Boxes.Where(b => PartyIds.Any(d => d == b.PartyID)); ParyIds是一个Int[]数组有72数字在里面
结果它生成的sql语句就超恐怖了。

换成另一种写法就ok了
var query = from it in ctx.Boxes where PartyIds.Contains(it.PartyID) select it;
生成的sql语句就跟我们正常写的差不多了
SELECT
[Extent1].[ID] AS [ID],
[Extent1].[Discriminator] AS [Discriminator],
[Extent1].[PartyID] AS [PartyID],
FROM [dbo].[Boxes] AS [Extent1]
WHERE ([Extent1].[Discriminator] IN ('Inbox','Outbox','Box')) AND ([Extent1].[PartyID] IN (89,88,87,86,85,84,83,82,81,80,79,78,77,76,75,72,71,70,69,68,67,66,65,64,63,62,61,60,59,55,54,53,52,51,50,49,48,47,46,45,44,43,42,41,40,39,38,37,36,35,34,33,32,31,30,29,28,27,26,25,24,23,22,21,20,19,18,17,16,3,2,1))

============================
var query2 = ctx.Boxes.Where(b => PartyIds.Any(d => d == b.PartyID)); ParyIds是一个Int[]数组有72数字在里面
var query = from it in ctx.Boxes where PartyIds.Contains(it.PartyID) select it;
