sqlserver批量还原多个数据库
·
sqlserver还原单个bak文件还是比较简单的，但是sqlserver自带的还原工具中没找到批量还原的地方，因此在网上找了下资料，收集到几个脚本，在sql server中执行后将创建三个存储过程，然后调用存储过程生成批量还原数据库的sql语句，再执行即可。
参考链接：Sql Server批量还原数据库_sql批量还原数据库_良人当归的博客-CSDN博客
以下就是批量还原数据库的全过程，亲测有效！！！
一共就3步：
第一步：部署存储过程；
第二步：执行exec语句，
第三步：拿到第二步的执行结果生成的slq语句，再次复制到sql执行语句的地方，即可完成快速批量还原数据库。
现在开始粘贴详细步骤：
第一步：按顺序执行创建一下3个存储过程；

end第二步：执行exec语句，生成sql语句
存储过程执行完毕后，再执行以下命令即可生成批量还原的sql语句
EXEC Usp_RestoreMuiteDataBaseFromPath @DatabBaseBakPath = N'E:\dbback\backfile', @RestoreDataPath = N'E:\db'
语句中包含两个路径：
DatabBaseBakPath：备份文件所在路径，路径下都为.bak文件
RestoreDataPath：数据库还原路径，数据库mdf及ldf文件存放位置
下方即为生成的sql语句，复制后再执行，即可批量还原数据库。
如下图：
第三步：拿到第二步的执行结果生成的slq语句，再次复制到sql执行语句的地方，即可完成快速批量还原数据库。
检查本地正确生成数据库文件，并打开数据库表检查数据和视图即可。一切都很完整，恢复非常迅速。
