The ORDER BY clause is invalid in views, inline functions, derived tables, subqueries, and common ta...

本文探讨了在SQL Server的视图定义中使用ORDER BY的限制及其原因,并提供了一个解决办法:通过添加TOP 100 PERCENT来绕过这一限制。此外,还讨论了直接在从视图选择的查询中使用ORDER BY的情况。

Just like in sub queries, you can't use ORDER BY in a view definition in sql server unless you also use TOP.

The reason for this is that Views are acted upon as if they where tables, and tables in sql server (in fact, in any relational database) are considered as not ordered sets.
Just like there is no meaning to the order of records stored in a table, there is also no meaning to the order of records fetched by a view.
You can use a dirty hack and write SELECT TOP 100 PERCENT ... and then use ORDER BY, but I doubt if it has any meaning at all.

Having said all that, you can of course use ORDER BY in any query that selects from a view.
