Sql server 更改现有约束/规则/程序上的引用\u标识符

我目前正在使用2008-r2服务器上的一个旧ish数据库，该数据库使用了许多对象，这些对象是在Quoted Identifier设置为off时创建的

我主要关注这些类型：

CHECK_CONSTRAINT
DEFAULT_CONSTRAINT
RULE
SQL_SCALAR_FUNCTION
SQL_STORED_PROCEDURE
SQL_TRIGGER
VIEW

我现在正试图更改引用的标识符设置，这让我立即感到困惑，因为我发现我甚至不能更改约束

---

对于限制：我认为我必须以某种方式进行临时克隆/复制，删除原始副本，然后使用副本和设置为ON的引用的_标识符重新创建它们，但我真的不知道如何做到这一点或如何自动化这一点，因为我的SQL技能有限。有人能帮我吗？或者有人知道更简单的替代方法吗？

为该数据库编写脚本，删除所有引用的标识符，从脚本中重新创建数据库并重新导入数据（MS SS中包含该向导）

这种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：

---

我在一个安装过程中遇到了一个错误，导致引用的标识符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…）

由于使用过滤索引和查询通知等功能需要启用QUOTED_IDENTIFIER，因此我想找到一种方法来查找所有关闭的索引并启用它

在这个网站上研究这个问题时，我发现了这篇（以及其他一些）文章，但我发现没有一篇文章能够在不重新生成所有SQL脚本（我实际上有数千个需要修复的对象）或编写C#代码的情况下很好地解决这个问题

所以我开发了一种基于SQL的处理方法。这将重新编译所有进程，并生成由于某种原因无法编译的任何进程的列表。我知道这不能处理不同的模式（dbo与sales与其他模式），但您可以根据需要对此进行调整。在我的情况下，我不需要担心这个

我已经更改了@Earl编写的脚本（见上文），以便它能够为SQL Server 2016及更高版本创建或更改模式，并与模式一起工作

它仍然不是完美的，因为找到“创建”部分并不简单

你的剧本帮助了我们。非常感谢。@Earl；非常感谢你。
