批量还原数据库 SQL Server 2008

1.如果你够懒，不想一步一步点路径，一步一步选择

2.如果你连单个备份数据库的存储过程都不想多执行,一般每还原一个需要修改数据库名

下面的脚本适合你：

/**********************************************
    Description:This script help you restore database batch.
    Pay attention:You'd better name the database like databaseName+number.
    The database name is nessasery.
    
    This script not perfect,and please make it progress if you want.
