我需要能够为SQL Server 2008中的现有表获取CREATE脚本.我假设我可以通过以某种方式查询sys.tables来执行此操作,但是这不会返回给我CREATE脚本数据.

这可能对你有所帮助.此脚本为任何表生成索引,FK,PK和公共结构.
例如 -
DDL:

是指您希望创建生成CREATE脚本的TSQL脚本,还是使用SQL SERVER Management Studio中的管理工具生成Create脚本？
如果是后者,则只需右键单击一个表,然后选择脚本表为 - >创建到 - >新查询窗口.
如果要编写整个数据库脚本,请右键单击数据库并选择"任务" - >"生成脚本...",然后按照向导进行操作
否则就是从各种系统表中选择各种有趣的东西.
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：
我没有时间正确测试它，我只在 SQL Server 2012/4 上测试了它
下一个版本将改变 FK 的生成，因为它们需要在末尾添加。否则他们可能会失败。
任何评论将不胜感激。

“最简单的方法是使用 SQL Management Studio 的内置功能”\n但是...\n我已经用一个函数和几个过程解决了这个问题。\n例如，获取名为 \' 的表的创建表table_name\'，您只需执行名为 sp_ppinScriptTabla 的过程：
\n\nExec sp_ppinScriptTabla \'table_name\'\n这是tsql脚本代码：

我意识到这个问题已经过时了,但是最近我刚刚开始进行搜索,所以我想我会发布上述答案的替代方案.
如果您希望create在.Net中以编程方式生成脚本,我强烈建议您查看服务器管理对象(SMO)或分布式管理对象(DMO) - 具体取决于您使用的SQL Server版本(前者是2005 +,后者2000).使用这些库,脚本编写表非常简单:
Server server = new Server(".");
Database northwind = server.Databases["Northwind"];
Table categories = northwind.Tables["Categories"];
StringCollection script = categories.Script();
string[] scriptArray = new string[script.Count];
script.CopyTo(scriptArray, 0);
