如何使用 Microsoft SQL Server Management Studio 为数据库中的所有触发器生成脚本

How to Generate Scripts For All Triggers in Database Using Microsoft SQL Server Management Studio

提问by Grasshopper

I'd like to generate an SQL Script that contains the SQL to create all of the triggers that exist in our database. The triggers were added directly via the SSMS query pane so, there is currently no source other than the trigger on the database itself.

我想生成一个包含 SQL 的 SQL 脚本，以创建我们数据库中存在的所有触发器。触发器是通过 SSMS 查询窗格直接添加的，因此，除了数据库本身的触发器之外，目前没有其他来源。

I have already tried the method where you right-click the database, select Tasks->Generate Scriptsand used the "Script Entire Database and All Objects" option. While this does create a SQL script for the tables and constraints, it does not generate SQL for the triggers.

我已经尝试过右键单击数据库，选择Tasks->Generate Scripts并使用“脚本整个数据库和所有对象”选项的方法。虽然这确实为表和约束创建了 SQL 脚本，但它不会为触发器生成 SQL。

I also understand that I can right click on each trigger in the database and select the Generate SQL Script option but, there is currently 46 tables under audit (For Insert, Update, and Delete).

我也知道我可以右键单击数据库中的每个触发器并选择“生成 SQL 脚本”选项，但是，目前有 46 个表正在审核中（用于插入、更新和删除）。

Rather manually generate an insert, update, and delete trigger script for each of the 46 tables, is there an easier way to do this? Or, should I start clicking, copying, and pasting?

而是为 46 个表中的每一个手动生成插入、更新和删除触发器脚本，有没有更简单的方法来做到这一点？或者，我应该开始单击、复制和粘贴吗？

Database-> Tasks-> Generate Scripts -> Next -> Next

数据库-> 任务-> 生成脚本-> 下一步-> 下一步

On Choose Script OptionsUI, under Table/View Options Heading, set Script Triggers to True.

在选择脚本选项UI 上的表/视图选项标题下，将脚本触发器设置为 True。

I know the answer has been accepted already, but want to provide another solution for cases when for some reason SSMS wizard is not able to generate script for triggers (in my case it was MSSQL2008R2)

我知道答案已经被接受，但想为由于某种原因 SSMS 向导无法为触发器生成脚本的情况提供另一种解决方案（在我的情况下是 MSSQL2008R2）

This solution is based on idea from danaabove, but uses 'sql_modules' instead to provide the full code of the trigger if it exceeds 4000 chars (restriction of 'text' column of 'syscomments' view)

此解决方案基于上述dana 的想法，但如果超过 4000 个字符，则使用“sql_modules”来提供触发器的完整代码（限制“syscomments”视图的“text”列）

select [definition],'GO' from sys.sql_modules m
inner join sys.objects obj on obj.object_id=m.object_id 
 where obj.type ='TR'

Right click on the results grid and then "Save results as..." saves to file with formatting preserved

右键单击结果网格，然后“将结果另存为...”保存到文件并保留格式

How about this?

这个怎么样？

select text from syscomments where text like '%CREATE TRIGGER%'

select text from syscomments where text like '%CREATE TRIGGER%'

EDIT- per jj's comment below, syscommentsis deprecated and will be removed in the future. Please use either the wizard-based or script-based solutions listed above moving forward :)

编辑- 根据下面 jj 的评论，syscomments已弃用，将来会被删除。请使用上面列出的基于向导或基于脚本的解决方案继续前进:)

To script all triggers you can define the stored procedure:

要编写所有触发器的脚本，您可以定义存储过程：

--     1 - Script CREATE only
--     2 - Script DROP + CREATE
