在 SQL Server 2005 上,是否可以在事务内删除并重新创建表(从另一个数据库复制)?

On SQL Server 2005, is it possible to drop and recreate a table (copy from another database) inside of a transaction?

此外,在事务期间尝试访问该表的任何进程是否会失败或等待事务完成?

Also, would any process trying to access that table during the transaction fail or wait for the transaction to complete?

推荐答案

将数据复制到不同的表中,然后切换旧表和新表.使用 sp_rename 或查看 使用分区切换有效传输数据.后一个选项更好,因为它保留了对表的所有权限和约束,但它确实需要企业版.

Copy the data into a different table, then switch the old and new tables. Use either sp_rename or see Transferring Data Efficiently by Using Partition Switching. The later option is better because it preserves all permissions and constraints on the table, but it does require Enterprise Edition.
