LINQ to SQL - 插入时出现死锁

我在SQL Server -2014标准版上遇到死锁问题。两个插入在聚集索引上死锁。LINQ to SQL - 插入时出现死锁

这是一个OLTP数据库和表是高插入和高读取，表已经与聚集索引的主键，并具有更多的13万条记录

DeadLock Graph

的SQL语句下面给出

显示您的代码。 –

还可以添加XML格式的死锁图形（右键单击>将事件数据提取为XML ...）。 –

请添加您的插入语句 – Dimgold

INSERT语句本身不会死锁对方。如果您在同一事务中调用SELECT WHERE UID=SCOPE_IDENTITY()，则服务器必须对包含UID的任何索引采用SHARED锁。这是因为您试图读取SCOPE_IDENTITY()的值，如果添加了另一行，这将会更改，导致数据不一致。如果您使用REPEATABLE READ隔离级别，则可能会导致死锁。

该解决方案非常简单 - 不要使用单独的SELECT。您可以使用INSERT的OUTPUT clause让所有的新的价值观，比如身份，默认值等：

INSERT INTO [dbo].[PatientBilledItem] 
([PatientBillUID], [EventOccuredDttm], [ServiceName], [BillableItemUID], [Amount], [CUser], [CWhen], [MUser], [MWhen], [StatusFlag], [OwnerOrganisationUID], [PatientBillableItemUID], [Discount], [NetAmount], [Description], [Comments], [ItemMultiplier], [BSMDDUID], [ItemName], [DiscountAuthorizedBy], [ConsultantShare], [ServiceTax], [CareProviderUID], [QNUOMUID], [SpecialAmount], [IsRefunded], [ConsultantDiscount], [EducationCess], [HigherEducationCess], [RecordedByUID], [OriginalCreditBillUID], [PatientPackageItemUID], [BatchID], [VATPercentage], [InternalCost], [CalculateTaxOnMRP], [StoreUID], [BillPackageUID], [SplitDiscount], [RSLVLUID], [ParentUID], [PackageItemAmount], [RoundOff], [AuthNo], [ExpiryDttm], [BILGRDUID], [ApprovalCode], [ApprovedBy], [InternalBatchID]) 
OUTPUT inserted.UID,inserted.Timestamp 
VALUES ......

你可以用快照隔离级别一起使用能降低交易之间的粘连。

插入是使用LINQ自动生成的，隔离设置也是READ COMMITTED SNAPSHOT –

@SamsudeenB首先，你应该明确地指定它。其次，LINQ不'生成SQL，它是一种通用的查询语言。 LINQ到什么？ LINQ to SQL？ LINQ to Entities？什么ORM版本？什么是确切的.NET代码？ *交易*代码在哪里？ –

我的意思是插入是通过LINQ到SQL –

根据所提供的信息，第一个假设是，这些死锁是由以下SELECT报表需要以下缺失索引

CREATE /*UNIQUE*/ NONCLUSTERED INDEX IUN_PatientBilledItem_UID_#_TIMESTAMP 
ON dbo.PatientBilledItem (UID) 
INCLUDE(TIMESTAMP)

或

CREATE /*UNIQUE*/ NONCLUSTERED INDEX IUN_PatientBilledItem_UID_TIMESTAMP 
ON dbo.PatientBilledItem (UID, TIMESTAMP)

之一引起的：

SELECT [t0].[UID], [t0].[TIMESTAMP] 
FROM [dbo].[PatientBilledItem] AS [t0] 
WHERE [t0].[UID] = (SCOPE_IDENTITY())

其中生成RangeS-S锁（也因为se TX隔离级别为SERIALIZABLE）。

注意：如果当前索引具有唯一值或唯一对值（复合索引），则取消注释/*UNIQUE*/关键字。
