推荐答案

开始阅读MSDN文档：

SELECT - SQL命令 - WITH子句 [ ^ ]

视图 [ ^ ]

你会发现很多例子，你可以列出所有的差异。



这里列出的基本差异很少：

SQL视图和WITH子句之间的差异 - 堆栈溢出 [ ^ ]

Start reading MSDN documentation:
SELECT - SQL Command - WITH Clause[^]
Views[^]
There you'll find tons of examples and you'll be able to list all differences.

Few basic differences were listed here:
Difference between SQL View and WITH clause - Stack Overflow[^]

SQL views和条款非常相似。



一些差异

视图是数据库对象， WITH 是DML中使用的子句。

查看在数据库中创建实际对象，使用语句只是单个查询的一部分。

SQL views and with clauses are very similar to each other.

Some difference
VIEW is a database object, WITH is a clause that is used in DML.
View create an actual object in the database, With statements are only part if a single query.
