SQL SERVER2005 数据库,用户权限迁移实录

　标签：SQL 迁移数据库权限实录　　　 [推送到技术圈]

今天早上昏昏欲睡，看来昨天电影看多了，有一个Q群网友GEELY问到，说如果把SQL SERVER里面的用户权限做迁移，从A迁移到B，当时就挑起兴趣了，之前都是做过数据库的迁移，就是数据库分离，然后附加！安全一点的就是备份，恢复！

用户安全性的迁移貌似没做过，在网上Google了一下，在这里记录了一些信息，列举如下：

环境介绍”

Server Name: SCSQL,Contoso.com IP:192.168.100.125

2. Server Name: SQL2. Contoso.com IP:192.168.100.125

迁移数据库对象： database: SMS_GDA

步骤如下：

1. 在SCSQL.CONTOSO.COM下备份数据库SMS_GDA（完整备份）到 D:\bak\SMS_GDA.BAK,

2. 把SMS_GDA.BAK,复制到SQL2.CONTOSO.COM上，恢复数据库SMS_GDA.BAK

3. 在SCSQL.contoso.com上执行以下语句:

USE master
GO
IF OBJECT_ID ('sp_hexadecimal') IS NOT NULL
    DROP PROCEDURE sp_hexadecimal
GO
CREATE PROCEDURE sp_hexadecimal
        @binvalue varbinary(256),
        @hexvalue varchar (514) OUTPUT
AS
DECLARE @charvalue varchar (514)
DECLARE @i int
DECLARE @length int
DECLARE @hexstring char(16)
SELECT @charvalue = '0x'
SELECT @i = 1
SELECT @length = DATALENGTH (@binvalue)
SELECT @hexstring = '0123456789ABCDEF'
WHILE (@i <= @length)
BEGIN
    DECLARE @tempint int
    DECLARE @firstint int
    DECLARE @secondint int
    SELECT @tempint = CONVERT(int, SUBSTRING(@binvalue,@i,1))
    SELECT @firstint = FLOOR(@tempint/16)
    SELECT @secondint = @tempint - (@firstint*16)
    SELECT @charvalue = @charvalue +
        SUBSTRING(@hexstring, @firstint+1, 1) +
        SUBSTRING(@hexstring, @secondint+1, 1)
    SELECT @i = @i + 1
END

SELECT @hexvalue = @charvalue

4. 在SCSQL.CONTOSO.COM下，查看master数据库的存储过程，会多了2个sp.help.revlogin, sp_hexadecimal
