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. SCSQL.CONTOSO.COM下备份数据库SMS_GDA(完整备份)到 D:\bak\SMS_GDA.BAK,
2. SMS_GDA.BAK,复制到SQL2.CONTOSO.COM上,恢复数据库SMS_GDA.BAK
3. 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
GO

    DECLARE login_curs CURSOR FOR

            SELECT p.sid, p.name, p.type, p.is_disabled, p.default_database_name, l.hasaccess, l.denylogin FROM

OPEN login_curs

FETCH NEXT FROM login_curs INTO @SID_varbinary, @name, @type, @is_disabled, @defaultdb, @hasaccess, @denylogin
IF (@@fetch_status = -1)
BEGIN
    PRINT 'No login(s) found.'
    CLOSE login_curs
    DEALLOCATE login_curs
    RETURN -1
END
SET @tmpstr = '/* sp_help_revlogin script '
PRINT @tmpstr
SET @tmpstr = '** Generated ' + CONVERT (varchar, GETDATE()) + ' on ' + @@SERVERNAME + ' */

PRINT @tmpstr
PRINT ''

        BEGIN -- NT authenticated account/group

            SET @tmpstr = 'CREATE LOGIN ' + QUOTENAME( @name ) + ' FROM WINDOWS WITH DEFAULT_DATABASE = [' + @defaultdb + ']'
        END
        ELSE BEGIN -- SQL Server authentication
                -- obtain password and sid
                        SET @PWD_varbinary = CAST( LOGINPROPERTY( @name, 'PasswordHash' ) AS varbinary (256) )
                EXEC sp_hexadecimal @PWD_varbinary, @PWD_string OUT
                EXEC sp_hexadecimal @SID_varbinary,@SID_string OUT

                SELECT @is_policy_checked = CASE is_policy_checked WHEN 1 THEN 'ON' WHEN 0 THEN 'OFF' ELSE NULL END FROM sys.sql_logins WHERE name = @name
                SELECT @is_expiration_checked = CASE is_expiration_checked WHEN 1 THEN 'ON' WHEN 0 THEN 'OFF' ELSE NULL END FROM sys.sql_logins WHERE name = @name
    
                        SET @tmpstr = 'CREATE LOGIN ' + QUOTENAME( @name ) + ' WITH PASSWORD = ' + @PWD_string + ' HASHED, SID = ' + @SID_string + ', DEFAULT_DATABASE = [' + @defaultdb + ']'

                IF ( @is_policy_checked IS NOT NULL )
                BEGIN
                    SET @tmpstr = @tmpstr + ', CHECK_POLICY = ' + @is_policy_checked
                END
                IF ( @is_expiration_checked IS NOT NULL )
                BEGIN
                    SET @tmpstr = @tmpstr + ', CHECK_EXPIRATION = ' + @is_expiration_checked
                END
        END
        IF (@denylogin = 1)
        BEGIN -- login is denied access
            SET @tmpstr = @tmpstr + '; DENY CONNECT SQL TO ' + QUOTENAME( @name )
        END
        ELSE IF (@hasaccess = 0)
        BEGIN -- login exists but does not have access
            SET @tmpstr = @tmpstr + '; REVOKE CONNECT SQL TO ' + QUOTENAME( @name )
        END
        IF (@is_disabled = 1)
        BEGIN -- login is disabled
            SET @tmpstr = @tmpstr + '; ALTER LOGIN ' + QUOTENAME( @name ) + ' DISABLE'
        END
        PRINT @tmpstr
    END

    FETCH NEXT FROM login_curs INTO @SID_varbinary, @name, @type, @is_disabled, @defaultdb, @hasaccess, @denylogin
     END
CLOSE login_curs
DEALLOCATE login_curs
RETURN 0
GO

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

5. 再次执行代码:
EXEC sp_help_revlogin
6. 复制执行代码后的结果
 


7.在 SQL2.CONTOSO.COM 查询分析器上执行,粘贴过来的代码
其实大家从图中已经可以看出来,在SCSQL.CONTOSO.COM的用户都过来了,语句中出错的是已经存在的用户,大家可以在事后去检查一下,并去验证登录请求
