Sql server sql server-带游标的触发器

我正在尝试设计一个接收订单行的登录表，然后触发器将数据发送到相应的表（即客户、订单、订单行）

我很容易在MySQL中使用新的和旧的关键字做到这一点，但是我在SQL Server中遇到了一些问题

首先，这是解决这类问题的最佳方法吗

其次，如果是，我尝试创建一个触发器，它使用游标在SQLServer中迭代插入的表。不幸的是，我总是出错

味精16916，第16级，状态1，程序原始b2c行，第17行[批次起始行6]
名为“ins_cusor”的游标不存在

我已附上以下代码（为了简化，删除了订单和订单行表的代码）

---

首先以该名称创建过程，然后执行

---

因为它找不到光标。

所以我发现了拼写错误。。。这就是为什么我得到了错误。。。我的坏朋友，对第一个问题有什么评论吗？是我想要实现的最佳方法吗？键入

OPEN ins\u cursor而不是
打开插件-您应该始终为所使用的任何
varchar
变量和参数提供长度。否则，最终的SQL变量只有一个字符长——通常不是您想要的……哦，天哪，触发器中的游标！为什么需要遍历行？您可以使用
inserted
合并所需的表。这是最好的方法吗？这是一个无法准确评估的问题，如果不充分了解您的模式以及导致您找到此“解决方案”的原因。我会毫不犹豫地说不，但那纯粹是猜测。在sql server中编写触发器是很困难的——对于那些没有tsql经验和正确思维的人来说，这不是一件容易的事情。sql server中的触发器在批处理级别执行，并且必须处理由触发statemet生成的任意数量的行。
