oc检查表并输出一个字符串，该字符串是正确的CREATETRIGGER语句。。。喜欢代码自动生成。我更喜欢动态sql而不是代码生成。是否也可以检查“错误”更新？像更新t1 set c1=c1-不应该跟踪这些内容…您使用的是什么版本的SQL Server？自SQL 2008以来，我们已经进行了更改数据捕获。此外，在SQL 2016中，我们得到了时态表。这将起作用，但我正在寻找一种更通用的解决方案，在这种解决方案中，我不需要为每个表指定每个触发器中的每一列。我希望有一个更具活力和可恢复性的解决方案。对于交叉应用，仍然+1。@Jaster，关系数据库被设计为具有稳定的模式，其中列是预先知道的，并且不会经常更改。快速搜索“sp_executesql in trigger”会告诉您，不能在引用

插入的

或

删除的

表的触发器中运行动态SQL。动态SQL在不同的单独上下文中执行。人们建议将插入的

表复制到某个临时表中，并在动态SQL中引用该临时表。我不确定它是否会工作，您仍然需要以某种方式为temp表定义列。我将仔细查看
更改数据捕获
功能。看起来需要sql Generarator。。。但是你为什么要把身份证给nvarchar？（该列不需要跟踪）@Jaster，你是对的，包含
ID
列没有多大意义，因为它不应该更改。同时，我没有包括
Version
列，因为它总是变化，并且它的实际值通常没有有用的（历史）意义。我希望查询的总体轮廓能够清楚地说明如何根据需要添加更多的列。我正在寻找一种更通用的解决方案，可以应用于多个表，而无需指定每一列+1进行正确的空检查并理解版本列。我只能考虑SQLCLR触发器，它可以动态地构建和执行SQL。根据vladimirs的回答，我猜这就是我的方向。。。只需要对所需的转换有更多的了解。@Jaster，将生成DML触发器代码的动态SQL代码放在。因此，您将保证记录数据更改的主DML触发器始终与表模式同步。但是，我不知道是否可以
更改
或
在DDL触发器中删除/创建
DML触发器。是否可以修改cdc过程中写入的数据。e、 更改用户/时间？您的意思是更改cdc表吗？是的，您可以更改CDC数据。CDC扫描程序读取事务日志并填充CDC表。然后，您可以对这些表执行任何DML命令，但在读取CDC表并填充history tablesSmart解决方案时不需要它，但我不需要动态脚本来生成触发器。我的问题是关于作为触发器一部分的动态sql，这似乎不是一个选项。
