但是,此时用户A存在于数据库A中,而新的MSSQL中虽然能创建用户A,但无法把权限赋于用户A。新创建一个用户B吧,用户A创建的表和其它信息就又无法访问。在这里找到了解决方法: 在源 SQL Server 上运行以下脚本。此脚本可在 master 数据库中创建名为 sp_hexadecimal 和 sp_help_revlogin 的两个存储过程。请在完成过程的创建之后继续执行第 2 步。 注意:下面的过程取决于 SQL Server 系统表。这些表的结构在 SQL Server 的不同版本之间可能会有变化,请不要直接从系统表中选择。 ----- Begin Script, Create sp_help_revlogin procedure ----- 复制代码 代码如下: 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(256) OUTPUT AS DECLARE @charvalue varchar(256) 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 IF OBJECT_ID ('sp_help_revlogin') IS NOT NULL DROP PROCEDURE sp_help_revlogin GO CREATE PROCEDURE sp_help_revlogin @login_name sysname = NULL AS DECLARE @name sysname DECLARE @xstatus int DECLARE @binpwd varbinary (256) DECLARE @txtpwd sysname DECLARE @tmpstr varchar (256) DECLARE @SID_varbinary varbinary(85) DECLARE @SID_string varchar(256) IF (@login_name IS NULL) DECLARE login_curs CURSOR FOR SELECT sid, name, xstatus, password FROM master..sysxlogins WHERE srvid IS NULL AND name <> 'sa' ELSE DECLARE login_curs CURSOR FOR SELECT sid, name, xstatus, password FROM master..sysxlogins WHERE srvid IS NULL AND name = @login_name OPEN login_curs FETCH NEXT FROM login_curs INTO @SID_varbinary, @name, @xstatus, @binpwd 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 '' PRINT 'DECLARE @pwd sysname' WHILE (@@fetch_status <> -1) BEGIN IF (@@fetch_status <> -2) BEGIN PRINT '' SET @tmpstr = '-- Login: ' + @name PRINT @tmpstr IF (@xstatus & 4) = 4 BEGIN -- NT authenticated account/group IF (@xstatus & 1) = 1 BEGIN -- NT login is denied access SET @tmpstr = 'EXEC master..sp_denylogin ''' + @name + '''' PRINT @tmpstr END ELSE BEGIN -- NT login has access SET @tmpstr = 'EXEC master..sp_grantlogin ''' + @name + '''' PRINT @tmpstr END END ELSE BEGIN -- SQL Server authentication IF (@binpwd IS NOT NULL) BEGIN -- Non-null password EXEC sp_hexadecimal @binpwd, @txtpwd OUT IF (@xstatus & 2048) = 2048 SET @tmpstr = 'SET @pwd = CONVERT (varchar(256), ' + @txtpwd + ')' ELSE SET @tmpstr = 'SET @pwd = CONVERT (varbinary(256), ' + @txtpwd + ')' PRINT @tmpstr EXEC sp_hexadecimal @SID_varbinary,@SID_string OUT SET @tmpstr = 'EXEC master..sp_addlogin ''' + @name + ''', @pwd, @sid = ' + @SID_string + ', @encryptopt = ' END ELSE BEGIN -- Null password EXEC sp_hexadecimal @SID_varbinary,@SID_string OUT SET @tmpstr = 'EXEC master..sp_addlogin ''' + @name + ''', NULL, @sid = ' + @SID_string + ', @encryptopt = ' END IF (@xstatus & 2048) = 2048 -- login upgraded from 6.5 SET @tmpstr = @tmpstr + '''skip_encryption_old''' ELSE SET @tmpstr = @tmpstr + '''skip_encryption''' PRINT @tmpstr END END FETCH NEXT FROM login_curs INTO @SID_varbinary, @name, @xstatus, @binpwd END CLOSE login_curs DEALLOCATE login_curs RETURN 0 GO ----- End Script ----- 2. 在创建 sp_help_revlogin 存储过程后,请从源服务器上的查询分析器中运行 sp_help_revlogin 过程。sp_help_revlogin 存储过程可同时用于 SQL Server 7.0 和 SQL Server 2000。sp_help_revlogin 存储过程的输出是登录脚本,该脚本可创建带有原始 SID 和密码的登录。保存输出,然后将其粘贴到目标 SQL Server 上的查询分析器中,并运行它。例如:EXEC master..sp_help_revlogin 复制代码 代码如下: SP_DEFAULTDB 'cyiyun','DB_WAYUP' 第1步后,在源服务器上运行sp_help_revlogin后,会产生创建用户数据的SQL,例如: 复制代码 代码如下: /* sp_help_revlogin script ** Generated 06 24 2009 1:40PM on WORKGROU-B1XTVC */ DECLARE @pwd sysname -- Login: hxtest SET @pwd = CONVERT (varbinary(256), 0x0100CF4E7D342B359438E4BCCA72E6C83F44FCCF30C8016286DE2B359438E4BCCA72E6C83F44FCCF30C8016286DE) EXEC master..sp_addlogin '520web', @pwd, @sid = 0x1738BB6AD0CD24498F67FB5589E8EDCB, @encryptopt = 'skip_encryption' ...... 把这段直接在新服务器上运行,或者找到相应的用户名创建,就可以解决这个问题了! |
