SQL Server 实例之间传输登录名和密码的详细步骤

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
)
