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”
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106 107 108 109 110 111 112 113 114 115 116 117 118 119 120 121 122 123 124 125 126 127 128 129 130 131 132 133 134 135 136 137 138 139 140 | 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.'

2. 在服务器A 上运行
1 2 | 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。
