需要一些SQL帮助将记录和相关记录复制到相同的表中吗
我有3个相互关联的表中的记录。我试图复制记录，为用户提供填写表单的起点，而不是从头开始。我有一个可以正常工作的存储过程 <>最高级别的记录可以在中间层有许多相关的记录。我可以毫无问题地复制顶级记录并检索新记录的ID。我还可以复制中间级别的记录，并使用第一步中的新ID将其添加到表中。问题是，中级记录在第三级也有很多记录。我不知道如何将三级记录复制到它所属的每一个中级记录中。我从中间步骤获得新ID，但是它进入最后一条记录，所以所有第三级记录都被放在ID.的下面，我认为最后一步应该是中间步骤的子查询。这是我到目前为止所拥有的，并感谢任何能提供帮助的人需要一些SQL帮助将记录和相关记录复制到相同的表中吗,sql,sql-server,Sql,Sql Server,我有3个相互关联的表中的记录。我试图复制记录，为用户提供填写表单的起点，而不是从头开始。我有一个可以正常工作的存储过程 最高级别的记录可以在中间层有许多相关的记录。我可以毫无问题地复制顶级记录并检索新记录的ID。我还可以复制中间级别的记录，并使用第一步中的新ID将其添加到表中。问题是，中级记录在第三级也有很多记录。我不知道如何将三级记录复制到它所属的每一个中级记录中。我从中间步骤获得新ID，但是它进入最后一条记录，所以所有第三级记录都被放在ID.的下面，我认为最后一步应该是中间步骤的子查询。这是

最初的关系是什么样子的？您是否有可能发布您的示例数据和预期输出？您应该查看INSERT的output子句，它可以为您提供中间表的新ID，可能是@VladimirBaranov的副本，我将您的答案用作模板。我在编辑器中没有发现错误，但当我尝试执行时，它会说insert语句中的列比第一个“块”的values子句中的列少。但是当我单独执行第一个“块”时，它工作得很好。你知道这是什么原因吗？我不知道如何将脚本放在这个评论窗口中，否则我会发布它。@RandyB.，你应该回答你的问题，并在问题中添加这些细节。显示所有表的定义（DDL）（使用SSM为您编写
创建表的脚本）。向我们显示您试图运行的代码，并向我们显示您收到的确切错误消息。要在选择行中获取错误，请选择@NewQuoteID，[QA].[AssemblyName]，[QA].[AssemblyQuantifier]多部分标识符“无法显示”bound@RandyB. 对不起，我没有测试我自己的答案。我重写了答案，并在我的测试环境中进行了测试
