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

我想生成一个包含SQL的SQL脚本来创build我们的数据库中存在的所有触发器。 触发器直接通过SSMS查询窗格添加，因此除了数据库本身的触发器之外，目前没有其他来源。

我已经尝试了右键单击数据库的方法，select“ Tasks->Generate Scripts然后使用“脚本整个数据库和所有对象”选项。 虽然这会为表和约束创build一个SQL脚本，但不会为触发器生成SQL。

我也明白，我可以右键单击数据库中的每个触发器，然后select“生成SQL脚本”选项，但目前在审计（插入，更新和删除）下有46个表。

而是手动为46个表中的每一个生成插入，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，我应该开始点击，复制和粘贴？

Answer 1

数据库 – >任务 – >生成脚本 – >下一步 – >下一步

在select脚本选项 UI，在表格/视图选项标题下，将脚本触发器设置为True 。

Answer 2

我知道答案已经被接受了，但是当SSMS向导无法为触发器生成脚本时（在我的情况下，它是MSSQL2008R2）

这个解决scheme基于上面dana的想法，但是如果它超过4000个字符（限制'syscomments'视图的'text'列），则使用'sql_modules'来提供触发器的完整代码。

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

右键单击结果网格，然后“保存结果为…”保存到保存格式的文件中

Answer 3

这个怎么样？

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

编辑 – 根据jj的评论下面， syscomments已被弃用，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scheme前进:)

Answer 4

要脚本所有触发器，您可以定义存储过程：

 SET ansi_nulls ON GO SET quoted_identifier ON GO -- Procedure: -- [dbo].[Createscriptofalltriggers] -- -- Parameter: -- @InclDrop bit -- possible values: -- 0 - Script to drop the triggers is not generated. -- 1 - Script to drip the triggers is generated.

如何执行它：

 SET nocount ON DECLARE @return_value INT EXEC @return_value = [dbo].[Createscriptofalltriggers] @InclDrop = 1 SELECT 'Return Value' = @return_value 

走

Answer 5

使用syscomments可能不总是工作。 syscomments的文本列被限制为4000个字符。 超过的触发器将被截断。 您可能无法完全查看。

Answer 6

实际上，如果您查看sys.comments表，它有一个colid字段是一个数字列; 如果它长于最大值，那么数字> 1。 如果你要select一个大于1的colID，并复制两个（如果有2个logging），它会给你整个触发！
