我正在尝试获取SQL Server 2008中现有表的CREATE脚本。我假设我可以通过以某种方式查询sys.tables来做到这一点，但是这并没有返回CREATE脚本数据。
使用查询为现有表生成SQL创建脚本
Answers:
可能对您有帮助。该脚本为任何表生成索引，FK，PK和通用结构。
例如 -
DDL：

quotename()的，而不是'[' + thing + ']'
您是要创建一个生成CREATE脚本的TSQL脚本，还是要使用SQL SERVER Management Studio中的管理工具生成一个Create脚本？
如果是后者，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”即可。
如果要对整个数据库编写脚本，请右键单击该数据库，然后选择“任务->生成脚本...”，然后按照向导进行操作
否则，需要从各种系统表中选择各种有趣的东西。
我实际上是在寻找一种以语法方式获取这些内容的方法，因为它将从.NET应用程序运行以生成主脚本文件。

谢谢！我知道有一种方法可以将所有创建脚本都放在一个地方，您的回答指出了我要找出的地方。

我知道这个问题很旧，但是最近在我刚运行的搜索中弹出了这个问题，因此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，强烈建议您查看服务器管理对象（SMO）或分布式管理对象（DMO），具体取决于您所使用的SQL Server版本（前者是2005+，后者2000年）。使用这些库，编写表脚本很容易：
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);
这是具有更多信息的博客文章。
“最简单的方法是使用SQL Management Studio的内置功能”，但是...我已经通过一个函数和几个过程解决了它。例如，要获取名为“ table_name”的表的创建表，只需执行名为sp_ppinScriptTabla的过程：
Exec sp_ppinScriptTabla 'table_name'
这是tsql脚本代码：
Use Master

首先，我喜欢由devart编写的脚本，我想使用它，但是我发现了一些局限性，因此我决定对其进行改进：
- 我修复了将脚本限制为4000个字符的错误（仍然有一些疯狂的表格仍然超出了限制）
- 我修复了错误/限制，以防表使用非集群主键
- 我用引号替换了[[]
- 我添加了默认约束的名称
- 我更改了识别源表的逻辑
- 我添加了删除并重新创建表及其FK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
- 我在打印结果时固定了4000 varchar（）的限制
- 我用N代替了''
- 我添加了在执行期间生成消息的选项，因为我的最终脚本（带有插入内容）可能花费很长时间，因此我想知道它在做什么
- 我添加了“插入到”的代
我没有时间正确测试它，而仅在SQL Server 2012/4上测试了它
下一版本将改变FK的生成，因为需要在末尾添加它们。否则，它们可能会失败。
任何意见将不胜感激。

尼克，
Invalid object name 'sys.Tables'.任何想法吗？
@Nick：sys.tables存在是在SQL Server 2008中引入的。您正在使用哪个版本的SQL Server？您可以执行“ SELECT * from sys.tables”吗？您是否尝试过执行DevArt编写的脚本版本？你有同样的错误吗？

我正在使用SQL Server 2014，否，我无法执行

尼克
SELECT * FROM SYS.TABLES我收到与上面相同的无效对象名称错误。
“ SELECT * from sys.tables”与“ SELECT * FROM SYS.TABLES”不同。它旨在检查数据库排序规则。您是否正在使用CS（区分大小写）数据库排序规则？您是否以dbo身份登录？数据库的兼容性级别是否可能是SQL Server 2005（从2008年开始存在sys.tables）？

ildanny
@尼克：我更新了脚本并将sys.tables更改为sys.table，让我知道您是否仍然有问题。感谢您的反馈：）

这与@Devart的答案略有不同，因此您可以获取临时表的CREATE脚本。
请注意，由于@SQL变量是一种NVARCHAR(MAX)数据类型，您可能无法仅使用SSMS从结果中复制它。请参阅此问题以查看如何获取MAX字段的完整值。

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，然后逐步完成向导。您可以选择要编写脚本的对象，这一切将为您完成。
现在，如果您要使自己的OWN脚本执行相同的操作，则可能需要进行很多工作……
这为我工作，为我节省了大量时间和潜在的错误。目前尚不清楚向导将生成哪种类型的脚本。如果选择表，它确实会生成CREATE TABLE脚本。这个答案较早被否决了。有什么特殊原因吗？

@ jward01耸肩。不知道，通过SSMS向导的详细演练，它可能会获得更多的投票，显示您可以在其中选择包括索引和外键之类的选项。

BradC
我可以在SSMS v18.0预览版（可能是较早的版本）中确认，您可以打开“对象资源管理器”，展开数据库，展开“可编程性”，展开“类型”，展开“用户定义的表类型”，右键单击您的类型，然后单击“用户定义的脚本”。在“表类型为”选项中可以选择“创建到”脚本。

End
)

(
Case
When Exists (
Select id
From syscolumns

( object_name(id) = SO.name )
And
( name = column_name )
And
( columnproperty(id,name,'IsIdentity') = 1 )
)
Then 'IDENTITY(' +
Cast( ident_seed(SO.name) As varchar ) + ',' +
Cast( ident_incr(SO.name) As varchar ) + ')'
Else ''
End
) + ' ' +
(
Case

End
) + 'NULL ' +
(
Case
When information_schema.columns.COLUMN_DEFAULT IS NOT NULL

End
) + ', '
From information_schema.columns
Where
( table_name = SO.name )
Order by ordinal_position
FOR XML PATH('')) o (list)
Inner Join information_schema.table_constraints As TC On (
( TC.Table_name = SO.Name )
AND
( TC.Constraint_Type = 'PRIMARY KEY' )
And
( TC.TABLE_NAME = @vsTableName )

AND
( Name NOT IN ('dtproperties') )
Return @ScriptCommand
End
您可以这样触发Function：
Select [dbo].Get_Table_Script '<Your_Table_Name>'
尝试以下操作（使用“结果转换为文本”）：
SELECT
ISNULL(smsp.definition, ssmsp.definition) AS [Definition]
FROM
sys.all_objects AS sp
LEFT OUTER JOIN sys.sql_modules AS smsp ON smsp.object_id = sp.object_id
LEFT OUTER JOIN sys.system_sql_modules AS ssmsp ON ssmsp.object_id = sp.object_id
WHERE
(sp.type = N'V' OR sp.type = N'P' OR sp.type = N'RF' OR sp.type=N'PC')and(sp.name=N'YourObjectName' and SCHEMA_NAME(sp.schema_id)=N'dbo')
- C：检查约束
- D：默认约束
- F：外键约束
- L：日志
- P：存储过程
- PK：主键约束
- RF：复制过滤器存储过程
- S：系统表
- TR：触发
- U：用户表
- UQ：唯一约束
- V：检视
- X：扩展存储过程
干杯，
对于表不起作用（这是主要问题）。
