简介
本文介绍如何在 Windows 上运行的 SQL Server 的不同实例之间传输登录名和密码， 适用于 SQL mirroring ， SQL AG 中的本地logins的迁移或者同步。
也就说源服务器A可以是SQL mirroring ， SQL AG的principal DB 或者任意 一台新的独立的SQL DB
步骤如下
1. 首先在源服务器A “master”数据库中创建两个存储过程。 过程分别名为“sp_hexadecimal”和“sp_help_revlogin”
USE [master]
GO
IF OBJECT_ID ('sp_hexadecimal') IS NOT NULL
DROP PROCEDURE sp_hexadecimal
GO
CREATE PROCEDURE [dbo].[sp_hexadecimal]
(
@binvalue varbinary(256),
@hexvalue varchar (514) OUTPUT
)
AS
BEGIN
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 'sa'
ORDER BY p.name
END
ELSE
DECLARE login_curs CURSOR
FOR
SELECT p.sid, p.name, p.type, p.is_disabled, p.default_database_name, l.hasaccess, l.denylogin, p.default_language_name
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_name
ORDER BY p.name
OPEN login_curs
FETCH NEXT FROM login_curs INTO @SID_varbinary, @name, @type, @is_disabled, @defaultdb, @hasaccess, @denylogin, @defaultlanguage
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 ''
WHILE (@@fetch_status -1)
BEGIN
IF (@@fetch_status -2)
BEGIN
PRINT ''
SET @tmpstr = '-- Login: ' + @name
PRINT @tmpstr
SET @tmpstr='IF NOT EXISTS (SELECT * FROM sys.server_principals WHERE name = N'''+@name+''')
BEGIN'
Print @tmpstr
IF (@type IN ( 'G', 'U'))
BEGIN -- NT authenticated account/group
SET @tmpstr = 'CREATE LOGIN ' + QUOTENAME( @name ) + ' FROM WINDOWS WITH DEFAULT_DATABASE = [' + @defaultdb + ']' + ', DEFAULT_LANGUAGE = [' + @defaultlanguage + ']'
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
-- obtain password policy state
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 + ']' + ', DEFAULT_LANGUAGE = [' + @defaultlanguage + ']'
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
SET @Prefix = '
EXEC master.dbo.sp_addsrvrolemember @loginame='''
SET @tmpstrRole=''
SELECT @tmpstrRole = @tmpstrRole
+ CASE WHEN sysadmin = 1 THEN @Prefix + [LoginName] + ''', @rolename=''sysadmin''' ELSE '' END
+ CASE WHEN securityadmin = 1 THEN @Prefix + [LoginName] + ''', @rolename=''securityadmin''' ELSE '' END
+ CASE WHEN serveradmin = 1 THEN @Prefix + [LoginName] + ''', @rolename=''serveradmin''' ELSE '' END
+ CASE WHEN setupadmin = 1 THEN @Prefix + [LoginName] + ''', @rolename=''setupadmin''' ELSE '' END
+ CASE WHEN processadmin = 1 THEN @Prefix + [LoginName] + ''', @rolename=''processadmin''' ELSE '' END
+ CASE WHEN diskadmin = 1 THEN @Prefix + [LoginName] + ''', @rolename=''diskadmin''' ELSE '' END
+ CASE WHEN dbcreator = 1 THEN @Prefix + [LoginName] + ''', @rolename=''dbcreator''' ELSE '' END
+ CASE WHEN bulkadmin = 1 THEN @Prefix + [LoginName] + ''', @rolename=''bulkadmin''' ELSE '' END
FROM (
SELECT CONVERT(VARCHAR(100),SUSER_SNAME(sid)) AS [LoginName],
sysadmin,
securityadmin,
serveradmin,
setupadmin,
processadmin,
diskadmin,
dbcreator,
bulkadmin
FROM sys.syslogins
WHERE ( sysadmin0
OR securityadmin0
OR serveradmin0
OR setupadmin 0
OR processadmin 0
OR diskadmin0
OR dbcreator0
OR bulkadmin0
)
AND name=@name
) L
PRINT @tmpstr
PRINT @tmpstrRole
PRINT 'END'
END
FETCH NEXT FROM login_curs INTO @SID_varbinary, @name, @type, @is_disabled, @defaultdb, @hasaccess, @denylogin, @defaultlanguage
END
CLOSE login_curs
DEALLOCATE login_curs
RETURN 0
END
2. 在服务器A 上运行
EXEC sp_help_revlogin -- 结果中会输出所有账户以及其加密密码
3.最后，将需要同步的账户从上一步中copy出来，到 目标SQL DB中执行即可。
