使用 Query 为现有表生成 SQL 创建脚本

技术标签:
【中文标题】使用 Query 为现有表生成 SQL 创建脚本【英文标题】:Generate SQL Create Scripts for existing tables with Query 【发布时间】:2009-04-01 17:51:17 【问题描述】: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,但这并没有返回 CREATE 脚本数据。
【问题讨论】:
只是CREATE TABLE
或所有其他包袱,例如索引、关系、检查约束、触发器(保留触发顺序!),...?一旦您开始添加关系,创建顺序就变得至关重要。
【参考方案1】:
这可能对您有所帮助。此脚本为任何表生成索引、FK、PK 和通用结构。
例如-
DDL:
CREATE TABLE [dbo].[WorkOut](
[WorkOutID] [bigint] IDENTITY(1,1) NOT NULL,
[TimeSheetDate] [datetime] NOT NULL,
[DateOut] [datetime] NOT NULL,
[EmployeeID] [int] NOT NULL,

[DepartmentUID] [uniqueidentifier] NOT NULL,
[WorkPlaceUID] [uniqueidentifier] NULL,
[TeamUID] [uniqueidentifier] NULL,
[WorkShiftCD] [nvarchar](10) NULL,
[WorkHours] [real] NULL,
[AbsenceCode] [varchar](25) NULL,

How to Generate a CREATE TABLE Script For an Existing Table: Part 1
【讨论】:
@Devart 我已经更新了我的查询,请查看 ddl 的更新问题:***.com/questions/38998330/… 你应该使用quotename()
而不是'[' + thing + ']'
@Devart 您的脚本工作正常,但我收到 Msg 8115,Level 16,State 2,Line 21 算术溢出错误将表达式转换为表的数据类型 varchar:ddl for table:dbo.bizparsing 列: ruleID(PK,bigint, not null) bizName(varchar(100),not null) bizID (FK,bigint, not null)
感谢@Devart!对于其他人,要使用过滤器处理索引,我必须在第 136 行添加 + CASE WHEN ISNULL(i.filter_definition,'') = '' THEN '' ELSE ' WHERE ' + i.filter_definition END
+ CHAR(13)
将它放在一个循环中以返回每个 INFORMATION_SCHEMA.TABLES.TABLE_NAME 的结果有多容易?谢谢【参考方案2】:
您的意思是您希望创建一个生成 CREATE 脚本的 TSQL 脚本,还是使用 SQL SERVER Management Studio 中的管理工具来生成一个 Create 脚本?
如果是后者,只需右键单击一个表,然后选择 Script Table As -> Create To -> New Query Window。
如果您想要整个数据库脚本化,然后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了。
【讨论】:
我实际上是在寻找一种以编程方式获取这些内容的方法,因为这将从 .NET 应用程序运行以生成主脚本文件。【参考方案3】:我意识到这个问题很老,但它最近出现在我刚刚运行的搜索中,所以我想我会发布上述答案的替代方案。
如果您希望在 .Net 中以编程方式生成 create
脚本,我强烈建议您查看 Server Management Objects (SMO) 或 Distributed Management Objects (DMO) - 取决于您使用的 SQL Server 版本(前者是 2005+,后者是 2000)。使用这些库,编写表格脚本非常简单:
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);
Here 是一篇包含更多信息的博文。

【参考方案4】:“最简单的方法是使用 SQL Management Studio 的内置功能” 但... 我已经用一个函数和几个程序解决了它。 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'
这里是tsql脚本代码:

【讨论】:
【参考方案5】:首先我很喜欢devart写的脚本,我也想用它,但是我发现了一些限制,所以我决定改进它:
我修复了将脚本限制为 4000 个字符的错误(某些疯狂的表格仍然可能超出限制) 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 我添加了删除和重新创建表及其 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 我修正了打印结果时 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(插入)可能需要很长时间,以至于我想知道它在做什么 我添加了“插入”的生成我没有时间正确测试它,我只在 SQL Server 2012/4 上测试过
下一个版本会更改 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。

【讨论】:
我在尝试运行此程序时遇到无效对象错误 -Invalid object name 'sys.Tables'.
有什么想法吗?
@Nick: sys.tables exists 是在 SQL Server 2008 中引入的。您使用的是什么版本的 SQL Server?你可以执行 "SELECT * from sys.tables" 吗?你试过执行 DevArt 编写的脚本版本吗?你有同样的错误吗?
我使用的是 SQL Server 2014,不,我无法执行 SELECT * FROM SYS.TABLES
我收到与上述相同的无效对象名称错误。
“SELECT * from sys.tables”不同于“SELECT * FROM SYS.TABLES”。它旨在检查数据库排序规则。您是否使用 CS(区分大小写)数据库排序规则?您是否以 dbo 身份登录?有没有可能你的数据库兼容级别是 SQL Server 2005(sys.tables 从 2008 年开始存在)?
@Nick:我更新了我的脚本并将 sys.Tables 更改为 sys.table,如果您还有问题,请告诉我。感谢您的反馈:)【参考方案6】:
试试sp_helptext Equivalent for Tables?
【讨论】:
【参考方案7】:您忘记包含sp_ppinCamposIndice
的存储过程或函数脚本
【讨论】:
在这里找到它:github.com/thepirat000/All-Masters-SQL/blob/master/…【参考方案8】:这是 @Devart 的答案略有不同,因此您可以获得临时表的 CREATE 脚本。
请注意,由于 @SQL 变量是 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question 了解如何获取 MAX 字段的完整值。

【讨论】:
低估答案 很好的解决方案!但是,您必须手动处理 PK(和其他约束)。 是的。必须以这种方式搜索和使用,否则我无法手动创建表。我认为它有超过 50 列 :)。 sqlservercentral.com/forums/topic/… 在网上发布解决方案做得非常出色。【参考方案10】:我们可以让SQL通过导航生成创建表脚本
将表编写为 > CREATE To > 新查询编辑器窗口
【讨论】:
【参考方案11】: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,然后完成向导。您可以选择要编写脚本的对象,它会为您完成一切。
现在,如果您尝试让自己的 OWN 脚本来做同样的事情,那么您可能需要做很多工作......
【讨论】:
这对我有用,并为我节省了大量时间和潜在错误。目前尚不清楚该向导将生成哪种类型的脚本。如果您选择表,它确实会生成一个 CREATE TABLE 脚本。这个答案早些时候被否决了。有什么特别的原因吗? @jward01 耸耸肩。不知道,也许通过 SSMS 向导的详细演练会获得更多投票,显示您可以选择在哪里包含索引和外键等选项。 我可以在SSMS v18.0预览版(可能更早的版本)中确认,你可以打开Object Explorer,展开你的数据库,展开Programmability,展开Types,展开User-Defined Table Types,右击你的type 和“Script User-Defined Table Type as”选项可以选择“CREATE To”脚本。 如果您尝试自动化您正在设计的流程,这不是最简单的方法。【参考方案12】:既然我们提供了您所要求的替代方案..
如果您使用的是 .Net,您应该查看 Visual Studio 中的数据库发布向导。将表/数据脚本写入文本文件的简便方法。

不适用于表格(这是主要问题)。【参考方案16】:孤独的潜伏者,第一次海报...
扩展@Devart 和@ildanny 解决方案...
我需要为 db 中的所有表运行它,还需要针对链接服务器执行代码。
