In the standard mode of the Clients, a database command can be
sent to the server using the execute()
function
of the Session
. This functions returns the whole
result. With the info()
function, you can request some
information on your executed process. If an error occurs, an
exception with the error message will be thrown.
Usage
The standard execution works as follows:
- Create a new session instance with hostname, port, username and password.
- Call the
execute()
function of the session with the database commands as argument. - Receive the result of a successfully executed command. If an error occurs, an exception is thrown.
- Optionally, call
info()
to get some process information - Continue using the client (back to 2.), or close the session.
Example in PHP
Taken from our repository:
<?php /* * This example shows how database commands can be executed. * Documentation: http://basex.org/api * * (C) BaseX Team 2005-11, BSD License */ include("BaseXClient.php"); try { // initialize timer $start = microtime(true); // create session $session = new Session("localhost", 1984, "admin", "admin"); // perform command and print returned string print $session->execute("xquery 1 to 10"); // close session $session->close(); // print time needed $time = (microtime(true) - $start) * 1000; print "\n$time ms\n"; } catch (Exception $e) { // print exception print $e->getMessage(); } ?>
