修改SQL的sa密码时提示“2812：未能找到存储过程‘sp_password’”的解决办法

在“企业管理器”-“安全性”-“登录”里面对sa修改密码时，弹出错误提示：


按照此错误信息应该就是系统缺少‘sp_password’这个存储过程，所以只要给系统添加这个存储过程就可以了，具解决方式如下：

打开“查询分析器”，登录的时候选择“Windows验证”而非默认的“SQL Server身份验证”，在master下执行以下语句：

SET QUOTED_IDENTIFIER ON
GO
SET ANSI_NULLS OFF
GO
create procedure sp_password
@old sysname = NULL,        -- the old (current) password
@new sysname,               -- the new password
@loginame sysname = NULL    -- user to change password on
as
-- SETUP RUNTIME OPTIONS / DECLARE VARIABLES --
set nocount on
declare @self int
select @self = CASE WHEN @loginame is null THEN 1 ELSE 2 END
-- RESOLVE LOGIN NAME
if @loginame is null
select @loginame = suser_sname()
-- CHECK PERMISSIONS (SecurityAdmin per Richard Waymire) --
IF (not is_srvrolemember('securityadmin') = 1)
AND not @self = 1
begin
dbcc auditevent (107, @self, 0, @loginame, NULL, NULL, NULL)
raiserror(15210,-1,-1)
return (1)
end
ELSE
begin
dbcc auditevent (107, @self, 1, @loginame, NULL, NULL, NULL)
end
-- DISALLOW USER TRANSACTION --
set implicit_transactions off
IF (@@trancount > 0)
begin
raiserror(15002,-1,-1,'sp_password')
return (1)
end
-- RESOLVE LOGIN NAME (disallows nt names)
if not exists (select * from master.dbo.syslogins where
loginname = @loginame and isntname = 0)
begin
raiserror(15007,-1,-1,@loginame)
return (1)
end
-- IF non-SYSADMIN ATTEMPTING CHANGE TO SYSADMIN, REQUIRE PASSWORD (218078) --
if (@self <> 1 AND is_srvrolemember('sysadmin') = 0 AND exists
(SELECT * FROM master.dbo.syslogins WHERE loginname = @loginame and isntname = 0
AND sysadmin = 1) )
SELECT @self = 1
-- CHECK OLD PASSWORD IF NEEDED --
if (@self = 1 or @old is not null)
if not exists (select * from master.dbo.sysxlogins
where srvid IS NULL and
name = @loginame and
( (@old is null and password is null) or
(pwdcompare(@old,
password,
(CASE
WHEN
xstatus&2048
=
2048
THEN
1
ELSE
0 END)) = 1) )   )
begin
raiserror(15211,-1,-1)
return (1)
end
-- CHANGE THE PASSWORD --
update master.dbo.sysxlogins
set password = convert(varbinary(256), pwdencrypt(@new)), xdate2 = getdate(), xstatus = xstatus
& (~2048)
where name = @loginame and srvid IS NULL
-- UPDATE PROTECTION TIMESTAMP FOR MASTER DB, TO INDICATE SYSLOGINS CHANGE --
exec('use master grant all to null')
-- FINALIZATION: RETURN SUCCESS/FAILURE --
if @@error <> 0
return (1)
raiserror(15478,-1,-1)
return  (0) -- sp_password
GO
SET QUOTED_IDENTIFIER OFF
GO
SET ANSI_NULLS ON
GO

执行完此查询后，sa的密码就可以修改了。

注：请自行谨慎操作！！事先备份数据库！！

出现2812这个错误提示，应该是说sp_password这个东西不存在，而以上的语句，就是创建sp_password这个东西。

如果执行上面语句的时候出现错误：


解决方法：企业管理器——>工具——>SQL Server 配置属性——>服务器设置——>允许对系统目录直接进行修改，然后重新执行上面的语句。
