具有事务隔离级别的SQL Server死锁读取未提交

Question

即使我将事务级别设置为未提交，我也会遇到此死锁。有什么我做错了吗？我以为我想在这里弄脏读。

SET TRANSACTION ISOLATION LEVEL READ UNCOMMITTED;

   SELECT 
            DISTINCT 
            venueCourt.Id, 

错误

System.Data.SqlClient.SqlException: Transaction (Process ID 73) was deadlocked on thread | communication buffer resources with another process and has been chosen as the deadlock victim. Rerun the transaction.

Answer 1

如果查询与您并行，您可能会遇到死锁...虽然我对这样一个简单的查询感到非常惊讶。

尝试在查询结束时添加OPTION（MAXDOP 1）。
