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SQL脚本，其中包含创建数据库中存在的所有触发器的SQL。触发器是通过SSMS查询窗格直接添加的，因此，除了数据库本身上的触发器之外，目前没有其他源 我已经尝试过这样的方法：右键单击数据库，选择如何使用Microsoft SQL Server Management Studio为数据库中的所有触发器生成脚本,sql,sql-server-2008,triggers,Sql,Sql Server 2008,Triggers,我想生成一个SQL脚本，其中包含创建数据库中存在的所有触发器的SQL。触发器是通过SSMS查询窗格直接添加的，因此，除了数据库本身上的触发器之外，目前没有其他源 我已经尝试过这样的方法：右键单击数据库，选择Tasks->Generate Scripts，然后使用“为整个数据库和所有对象编写脚本”选项。虽然这会为表和约束创建SQL脚本，但不会为触发器生成SQL 我还了解到，我可以右键单击数据库中的每个触发器并选择GenerateSQL脚本选项，但目前有46个表正在接受审核（用于插入、更新和删除）
Tasks->Generate Scripts从syscomments中选择文本，其中的文本类似于“%CREATE TRIGGER%”编辑-根据jj下面的评论，
syscomments我知道答案已经被接受，但我想为由于某种原因SSMS向导无法生成触发器脚本的情况提供另一种解决方案（在我的例子中是MSSQLS2008R2） 此解决方案基于上面的想法，但如果触发器超过4000个字符，则使用“sql_模块”提供触发器的完整代码（限制“syscomments”视图的“text”列）
右键单击结果网格，然后“将结果另存为…”保存到保留格式的文件中为所有触发器编写脚本您可以定义存储过程：

这看起来确实会拉回触发器，但是，所有内容都在表的一行中，并且没有格式化。KPL的回答帮了我的忙。不过谢谢你的回答。我不知道syscomments表。很有趣。我没有想到这一点，但这是个好主意：）-1结果不包含我的触发器的全部文本。@MAW74656-叔叔。。。我想我的答案是为了更快速、更肮脏地使用GUI查找不带触发器的触发器。公认的答案可能最适合大多数人。然而，有时有一个低级的替代品是很好的。看起来伊戈尔比我走得更远，在这一点上，我可能会同意他的观点。但是，我会留下我的答案供参考。简要说明：syscomments已被弃用（将在SQL 2014后的某个时间删除），Microsoft建议在SSMS2012中使用sys.SQL_modules，通过单击“设置脚本选项”步骤中的“高级”可以找到“选项”对话框。如果只希望生成触发器，如何使用此对话框？选择sch.name作为架构名称，parent.name作为表名称，obj.name作为触发器名称，m.[定义]作为触发器，sys.sql\u模块中的定义为m internal JOIN sys.objects AS obj ON obj.object\u id=m.object\u id internal JOIN sys.objects AS parent.object\u id=obj.parent\u object\u id internal JOIN sys.schemas AS sch ON sch.schema\u id=parent.schema\u id其中obj.type='TR'
