<?php

// Server and database, prepares and executes a
// direct table open, and then performs a refresh
// using the edb_refresh() function, displaying

$con = edb_connect("type=remote;charset=Ansi;address=127.0.0.1;"+
                   "uid=Administrator;pwd=EDBDefault;database=Test");
if (!$con)
  {
  die("Could not connect: " . edb_errmsg());
  }

$cmd = edb_prepare($con,"customer",EDB_COMMAND_TABLE);
