SQL2000修改sa密码时提示【错误2812：未能找到储存过程’sp_passwoed’】的解决方法2022-08-09

1.我们在用SQL2000数据库经常会遇见忘记sa密码，需要修改sa密码，但是有时候修改sa密码时会提示   错误2812：未能找到储存过程’sp_passwoed’

2.遇到这种情况的解决方法是：打开开始菜单，找到SQL Server的程序组，选择运行程序组中的“查询分析器”，打开.

3.打开“查询分析器”后会有一个登录窗口，因为sa密码不能修改，所以在连接使用的地方选择第一项“windows身份验证”。如果操作系统中有多个SQL Server实例，请在上面SQL Server（S）项中，选择指定示例名。最后点确定，进入查询分析器.

4.在打开的窗口中把以下执行语句内容，全部复制到打开的查询分析新窗体中.

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

5.复制完成后，点执行按钮（即下图绿色三角按钮），或者键盘上按F5执行.

6.运行后，下方出现提示消息：命令已成功完成。这样就可以正常的修改SQL Server用户sa的密码了。
