Question

我正在尝试从一台服务器上的外键链接的2个表中复制数据，然后将它们插入到另一台服务器上的主数据库中。

第一个表将生成一个新的IDENTITY列，然后我想将其存储在变量中并将其插入到第二个表中。

我已尝试使用内部插入表和SCOPE_IDENTITY()但接收到REMOTE服务器上不允许的错误

Answer 1

@@IDENTITY和SCOPE_IDENTITY()是本地的

你正在使用链接服务器吗？检查一下： get @@Identity from another server(linked server)

Answer 2

要解决此问题，我最终在目标服务器上创建了脚本作为存储过程，然后我可以使用范围标识。性能也大大提高，然后我配置了一个新的链接服务器，启用了RPC out并远程调用该过程。它不是一个优雅的解决方案，但它只是暂时的

REMOTE服务器上不允许SCOPE_IDENTITY？
