Thanks for pointing out my mistake, Try following- if this help out :

/*Generate the 'sp_change_users_login' statements necessary to synch all users in all databases on the server.*/

set nocount on

set quoted_identifier off

declare @dbId int,

      @dbName varchar(255)

select @dbId = min(dbId) from master..sysdatabases where dbid > 3

while exists (select * from master..sysdatabases where dbid = @dbId)

   begin

      select @dbName =  name from master..sysdatabases where dbid = @dbId

      PRINT 'USE [' +@dbName+ ']'

      PRINT 'GO'

      exec("select 'exec sp_change_users_login ''UPDATE_ONE'',''' +name+ ''',''' +name+ ''''

              from [" +@dbName+ "]..sysusers where issqluser = 1 and status = 2 and uid > 2")

      PRINT 'GO'

      PRINT ''

      select @dbId = min(dbId) from master..sysdatabases where dbid > @dbId

   end

USE master

set nocount off
