我目前正在使用 2008-r2 服务器上的旧式数据库，该数据库使用了许多在 Quoted Identifier 设置为 off 的情况下创建的对象。
我主要看这些类型：
CHECK_CONSTRAINT
DEFAULT_CONSTRAINT
RULE
SQL_SCALAR_FUNCTION
SQL_STORED_PROCEDURE
SQL_TRIGGER
VIEW
我现在正在尝试更改引用标识符设置，因为我发现我什至无法更改约束，这让我立即感到困惑。
对于约束：我想我必须以某种方式制作一个临时克隆/副本，删除原始文件，然后使用副本重新创建它们，并将 Quoted_Identifier 设置为 ON，但我真的不知道如何执行此操作或如何执行此操作自动执行此操作，因为我的 SQL 技能有限。有人可以帮助我吗？或者有人知道更简单的替代方法吗？
我在安装过程中遇到了一个错误，导致 QUOTED_IDENTIFIER 在大量对象上随机打开/关闭（问题涉及过程、函数、触发器和视图......）。
因为使用过滤索引和查询通知之类的东西需要 QUOTED_IDENTIFIER ON，所以我想要一种方法来找到所有关闭的索引并将其打开。
在研究这个网站上的问题时，我发现了这个（以及其他一些）帖子，但我发现没有一个很好的方法可以在不重新生成所有 SQL 脚本的情况下做到这一点（我实际上有数千个需要修复的对象）或编写 C# 代码。
所以我开发了一种基于 SQL 的方法来处理它。这会重新编译所有 proc，并生成一个由于某种原因无法编译的列表。我知道这不能处理不同的模式（dbo 与销售与其他），但您可以根据需要对其进行调整。在我的情况下，我不需要担心这一点。

编写此数据库的脚本，删除所有 Quoted_Identifier OFF，从脚本重新创建数据库并重新导入数据（该向导包含在 MS SS 中）。
这个解决方案可能有很多味道。使用动态 sql /smo 技术解决了类似的问题： Change the ANSI_NULLS setting for all Stored Procedures in the Database
我已经更改了 @Earl 编写的脚本（见上文），以便它执行 CREATE OR ALTER，并且也适用于 SQL Server 2016 及更高版本的模式。
它仍然不完美，因为找到“CREATE”部分并不简单。
