使用查询为现有表生成SQL创建脚本
我正在尝试获取SQL Server 2008中现有表的创建脚本。我假设可以通过查询sys.tables来实现这一点，但是这不会返回创建脚本数据。最简单的方法是使用SQL Management Studio的内置功能 右键单击数据库，转到任务，生成脚本，然后浏览向导。您可以选择要编写脚本的对象，它将为您提供全部内容使用查询为现有表生成SQL创建脚本,sql,sql-server,tsql,Sql,Sql Server,Tsql,我正在尝试获取SQL Server 2008中现有表的创建脚本。我假设可以通过查询sys.tables来实现这一点，但是这不会返回创建脚本数据。最简单的方法是使用SQL Management Studio的内置功能 右键单击数据库，转到任务，生成脚本，然后浏览向导。您可以选择要编写脚本的对象，它将为您提供全部内容 现在，如果你想制作自己的脚本来做同样的事情，你可能需要做很多工作 您的意思是希望创建生成创建脚本的TSQL脚本，还是使用SQL SERVER Management Studio中的管理
现在，如果你想制作自己的脚本来做同样的事情，你可能需要做很多工作 您的意思是希望创建生成创建脚本的TSQL脚本，还是使用SQL SERVER Management Studio中的管理工具生成创建脚本 如果是后者，只需右键单击一个表，然后选择scripttable As->createto->newquerywindow 如果要编写整个数据库的脚本，请右键单击该数据库并选择任务-->生成脚本。。。然后按照向导操作
否则，就需要从各种系统表中选择各种有趣的东西 既然我们提供了你要求的替代品 如果您在.Net中，您应该查看Visual Studio中的数据库发布向导。将表/数据脚本化为文本文件的简单方法 使用SSMS，最简单的方法 您还可以为它配置选项（例如排序、语法、删除…创建） 否则，SSMS Tools Pack或CodePlex上的DbFriend可以帮助您生成脚本 但是 我用一个函数和几个过程解决了这个问题。 例如，要为名为“table_name”的表获取创建表，您只需执行名为sp_ppinScriptTabla的过程：
Exec sp_ppinScriptTabla 'table_name'

首先，我喜欢devart编写的脚本，我想使用它，但我发现了一些限制，所以我决定改进它：
- 我修复了将脚本限制在4000个字符的错误（某些疯狂的表仍然可能超出限制）
- 我修复了表使用非聚集主键时的错误/限制
- 我将“[”替换为quotename
- 我添加了默认约束的名称
- 我更改了逻辑以标识源表
- 我添加了删除并重新创建表及其FKs的可能性
- 我添加了生成特定属性的可能性
- 我添加了对表压缩的支持
- 我添加了为任意数量的表生成脚本的可能性
- 我修复了打印结果时4000 varchar（）的限制
- 我将“”替换为N“”
- 我添加了在执行期间生成消息的选项，因为我的最终脚本（带有insert-to）可能需要很长时间，我想知道它在做什么
- 我添加了“插入到”的生成
