SqlServer数据库迁移

1. 迁移 索引： --导出 数据库 的所有Index脚本 ----只生成索引脚本，不需要统计信息------------------ declare @tbname sysname ,@type char(1) set @tbname='';--表名，空返回所有表索引 set @type='1' ;--是否显示聚集索引,1显示聚集索引,2不显示聚集索

这段代码会在“master”数据库中创建两个存储过程。两个存储过程分别命名为“sp_hexadecimal”存储过程和“sp_help_revlogin”存储过程。

接下来运行sp_help_revlogin：exec sp_help_revlogin

3.给用户赋予对象权限：

--给数据库中的对象赋权
select 'grant '+ (case when type='U'  then ' select,insert,update,delete '
                       when type='V'  then ' select,insert,update,delete '
                       else ' exec ' end)
       +' on ['+name+'] to appconn'
 from sys.objects where is_ms_shipped=0  and type in('P','U','FN','V')

4.查询特定用户的权限，导出赋权脚本：

--原库用户权限导出
select       object_name(a.id)   as   objectname,  
        user_name(a.uid)   as   usename,  
        case   b.issqlrole   when   1   then   'Group   '
