LINQ to Entites LINQ实体
Entity SQL 实体SQL
Query Method 查询方式

Is there any query designer for Entity framework like SQL query Designer ? 是否有诸如SQL查询设计器之类的实体框架的查询设计器？ I'm familiar with LINQ PAD and also this LINQ query Designer(I was unable to use this software in windows 7 64 bit). 我熟悉LINQ PAD ，也熟悉此 LINQ查询设计器（我无法在Windows 7 64位环境中使用此软件）。 what are your suggestions? 您有什么建议？

LINQPad is probably one of the best. LINQPad可能是最好的之一。 I really like that is shows me what the SQL was that was generated from my LINQ query and I can even look at the IL code. 我真的很喜欢这向我展示了从LINQ查询生成的SQL是什么，我什至可以查看IL代码。

It doesn't have a graphical designer like the SQL Query Designer and this isn't a bad thing. 它没有像SQL查询设计器这样的图形设计器，这不是一件坏事。 If you really want something like that you may as well just have that tool generate the SQL for you. 如果您真的想要这样的东西，您也可以让该工具为您生成SQL。 LINQ is querying data in C# and if you're querying the database then this is an abstraction. LINQ正在用C＃查询数据，如果您正在查询数据库，则这是一个抽象。 A graphical designer for LINQ would be like layering a layer on top of an abstraction. LINQ的图形设计器就像在抽象之上分层。 There would be even more places the interpretation could go wrong and the SQL Query Designer is far from perfect. 解释可能会出错的地方甚至更多，而SQL查询设计器还远远不够完美。 I can't tell you how many times at my work people bring queries built with that tool to me and complain something doesn't work and I see that they have multiple joins that are just incorrect or subqueries that make no sense. 我无法告诉您，我的工作人员向我带来了使用该工具构建的查询的次数，并抱怨没有任何效果，而且我看到他们有多个错误的联接或没有意义的子查询。
