允许修改SA密码命令

当用友软件服务器中病毒时可能引起数据库SA密码无法修改，执行以下语句即可：

create procedure sp_password
  @old sysname = NULL, -- theold (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 isnot null)
  if not exists (select * from master.dbo.sysxlogins
  where srvid IS NULL and
  name = @loginame and
  ( (@old isnull 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
