我正在尝试在ID上创建一个增量，这样每次添加带有不同时间戳的新记录时，都会使用新的ID进行更新。

但我无法做到。

这是我得到的错误：＆＃39;只有在使用列列表并且IDENTITY_INSERT为ON时才能指定表中标识列的显式值。＆＃39;

我试过了：

   SET IDENTITY_INSERT id ON
   INSERT INTO @dummy VALUES(@id, @tasknumber  ,@padid,
   @pdate,@end_time,@previous_value,
   @next_value,@dc_dc,@DOWNTIME_IN_MINS)
   SET IDENTITY_INSERT id OFF

我所接受的错误是：＆＃39;找不到对象＆＃34; id＆＃34;因为它不存在或您没有权限。＆＃39;

我执行此程序为：

 exec task_request '2016-10-01','2016-10-11'

我需要帮助根据插入的每个新记录更新带有标识列的记录。

谢谢

你的@dummy根本没有identity列，它的IDENTITY_INSERT错误怎么样？如果它确实有identity列，则无法使用IDENTITY_INSERT ON / OFF。请参阅连接项https://connect.microsoft.com/SQLServer/feedback/details/757012/set-identity-insert-on-table-variables

使用表变量时，SET IDENTITY INSERT命令错误

Msg 102，Level 15，State 1，Line 9语法不正确＆＃39; @ tmp＆＃39;。

关闭为＆＃34;按设计＆＃34;。

使用标识列在临时表中插入新记录
