我需要编写一个脚本来提取 SQL 登录的密码并将其传播到另一台服务器。
我这样做了:
Declare @PasswordBinary varbinary(256)
Set @PasswordBinary = CAST(LOGINPROPERTY( @LoginName, 'PasswordHash' ) AS varbinary (256))
Exec sp_hexadecimal @PasswordBinary, @PasswordStr Out
sp_hexadecimal :
Create PROCEDURE [dbo].[sp_hexadecimal]
@binvalue varbinary(256),
@hexvalue varchar (514) OUTPUT
AS
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
我有一个变量
@SQL nvarchar(max) = 'CREATE LOGIN ' + QUOTENAME(@LoginName) + ' With PASSWORD = ' + @PasswordStr + ' HASHED'''
我将它发送到远程服务器上的存储过程,并在那里执行这个变量:
Exec (@SQL)
但我得到一个错误:
@SQL 变量设置为:'Create Login [Name] With password = 0x Hashed'
谢谢 :)
