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 <= @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
  END
  go
  IF OBJECT_ID ('sp_help_revlogin') IS NOT NULL
  DROP PROCEDURE sp_help_revlogin
  GO
  CREATE PROCEDURE [dbo].[sp_help_revlogin]   
  (
      @login_name sysname = NULL 
  )
  AS
  BEGIN
      DECLARE @name                     SYSNAME

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。
