我正在运行一个收到错误的脚本。当我注释掉脚本的一部分时，它说它成功了 - 但实际上并没有做任何事情。该脚本是多个目录中多个数据库的还原脚本。该脚本应该将这些数据库还原到与数据库同名的目录中。我将在这里附上脚本：

答案 0 :(得分：0)
如果我理解正确，您将在SQL Server 2012服务器上恢复备份。作为文档says，RESTORE HEADERONLY的结果集中有一个名为containment的额外列，该列不在SQL 2008中，但您的#bdev表没有containment柱。如果您添加它，则RESTORE HEADERONLY结果将与表格结构匹配。
就个人而言，我会使用外部脚本来代替TSQL。使用外部脚本处理文件更容易，并且所有动态SQL都难以阅读和排除故障。使用PowerShell中的SMO是一个选项，或者只使用您首选的脚本语言来执行TSQL。

我弄清楚问题是什么......从SQL 2008 R2到SQL 2012，在创建#bdev时还有其他列缺失。
我通过检查两个SQL服务器的表结构来解决了这个问题，并确定在SQL 2012中，他们添加了一个不在我脚本中的新列...添加此列时，脚本工作正常！
