SQLServer的Login迁移脚本

背景:公司的数据由SQLServer2008 R2升级至SQLServer2012，并配置了AlwaysOn，本脚本用于将主节点的Login迁移至辅助节点。

1.在主节点执行以下脚本创建存储过程：

USE masterGOIF OBJECT_ID ('sp_hexadecimal') IS NOT NULL  DROP PROCEDURE sp_hexadecimalGOCREATE PROCEDURE sp_hexadecimal    @binvalue varbinary(256),    @hexvalue varchar (514) OUTPUTASDECLARE @charvalue varchar (514)DECLARE @i intDECLARE @length intDECLARE @hexstring char(16)SELECT @charvalue = '0x'SELECT @i = 1SELECT @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 + 1ENDSELECT @hexvalue = @charvalueGO IF OBJECT_ID ('sp_help_revlogin') IS NOT NULL  DROP PROCEDURE sp_help_revloginGOCREATE PROCEDURE sp_help_revlogin @login_name sysname = NULL ASDECLARE @name sysnameDECLARE @type varchar (1)DECLARE @hasaccess intDECLARE @denylogin intDECLARE @is_disabled intDECLARE @PWD_varbinary  varbinary (256)DECLARE @PWD_string  varchar (514)DECLARE @SID_varbinary varbinary (85)DECLARE @SID_string varchar (514)DECLARE @tmpstr  varchar (1024)DECLARE @is_policy_checked varchar (3)DECLARE @is_expiration_checked varchar (3)DECLARE @defaultdb sysname IF (@login_name IS NULL)  DECLARE login_curs CURSOR FOR      SELECT p.sid, p.name, p.type, p.is_disabled, p.default_database_name, l.hasaccess, l.denylogin FROM sys.server_principals p LEFT JOIN sys.syslogins l      ON ( l.name = p.name ) WHERE p.type IN ( 'S', 'G', 'U' ) AND p.name <> 'sa'ELSE  DECLARE login_curs CURSOR FOR      SELECT p.sid, p.name, p.type, p.is_disabled, p.default_database_name, l.hasaccess, l.denylogin FROM sys.server_principals p LEFT JOIN sys.syslogins l      ON ( l.name = p.name ) WHERE p.type IN ( 'S', 'G', 'U' ) AND p.name = @login_nameOPEN login_cursFETCH NEXT FROM login_curs INTO @SID_varbinary, @name, @type, @is_disabled, @defaultdb, @hasaccess, @denyloginIF (@@fetch_status = -1)BEGIN  PRINT 'No login(s) found.'

2.在主节点执行存储过程，导出创建Login的SQL语句：

EXEC sp_help_revlogin 

3.将第2步生成的脚本进行删减后在辅助节点执行。

4.在主节点执行以下脚本，导出数据库用户的角色身份、对象权限，并在辅助节点执行：

--更改【此用户拥有的架构】select s.name,p.name,'ALTER AUTHORIZATION ON SCHEMA::['+s.name+'] TO ['+p.name+']'from sys.schemas s inner join sys.database_principals p on s.principal_id=p.principal_idwhere s.name <> p.name--授予【数据库角色成员身份】权限SELECT 'exec sp_addrolemember N'''+g.name+''', N'''+u.name+''''FROM sys.database_principals uinner join sys.database_role_members m on u.principal_id = m.member_principal_idinner join sys.database_principals g on g.principal_id = m.role_principal_idORDER BY g.name,u.name--授予【安全对象】权限SELECT N'grant '+B.permission_name  collate chinese_prc_ci_ai_ws+N' on ['+A.name+N'] to ['+C.name+N']'FROM sys.sysobjects A(NOLOCK) INNER JOIN sys.database_permissions B(NOLOCK) ON A.id=B.major_id INNER JOIN sys.database_principals C(NOLOCK) ON B.grantee_principal_id=C.principal_id--WHERE C.name='MyPrincipalName' --AND A.name='MyobjectName'--程序集权限查询及授予SELECT * FROM sys.types WHERE is_user_defined=1SELECT * FROM sys.table_typesSELECT pms.state_desc,pms.permission_name,pms.class_desc,stt.name,tt.name,psp.name,pms.state_desc+' '+pms.permission_name+' ON '+class_desc+'::['+stt.name+'].['+tt.name+'] TO ['+psp.name+']'collate Chinese_PRC_Stroke_CI_AS  FROM sys.table_types AS ttINNER JOIN sys.schemas AS stt ON stt.schema_id = tt.schema_idINNER JOIN sys.database_permissions AS pms ON pms.major_id=tt.user_type_idINNER JOIN sys.database_principals AS psp ON psp.principal_id = pms.grantee_principal_idWHERE pms.class=6 AND pms.minor_id=0 AND pms.state = 'G'
