实体框架4.0:如何看SQL语句SaveChanges方法 [英] Entity Framework 4.0: How to see SQL statements for SaveChanges method
问题描述
我以前用的是context.Log用于跟踪的LINQ to SQL生成的SQL语句,如图<一href="http://stackoverflow.com/questions/11156124/sql-server-query-visualizer-cannot-see-generated-sql-query/11201832#11201832">Sql服务器查询可视化工具 - 无法看到生成的SQL查询
I used to use the context.Log for tracing LINQ to SQL generated SQL Statements as shown in Sql Server Query Visualizer – Cannot see generated SQL Query
context.Log = new OutputWindowWriter();
有关EF,有什么相似,容易像上面的方法呢?
For EF, is there anything similar and easy like the above approach?
推荐答案
在一般的,你可以连接内置的示踪剂,或通过简单的任何记录
In general you can hook up the built-in tracer or any logger by simple
context.Database.Log = msg => Trace.WriteLine(msg);
在的DbContext构造。 查看更多在 MSDN 。从MS其他的一些方法是这里(全部基于<一href="http://msdn.microsoft.com/en-us/library/system.data.linq.datacontext.log.aspx">DataContext.Log属性)。
in the DbContext constructor. See more in MSDN. Some other approaches from MS are here (all based on DataContext.Log property).
谈起由内特中提到的离合器的解决方案,它不与EF V6工作(见的这个错误报告)
Talking about the Clutch solution mentioned by Nate, it doesn't work with EF v6 (see this bug-report).
