Descrizione

Stile procedurale

string maxdb_error ( resource $link )

Stile orientato agli oggetti

string $maxdb->error;

The maxdb_error() function is identical to the corresponding maxdb_errno() function in every way, except instead of returning an integer error code the maxdb_error() function will return a string representation of the last error to occur for the database connection represented by the link parameter. If no error has occurred, this function will return an empty string.

Valori restituiti

A string that describes the error. An empty string if no error occurred.

Example #1 Stile orientato agli oggetti

<?php
$maxdb 
= new maxdb("localhost""MONA""RED""DEMODB");

/* check connection */
if (maxdb_connect_errno()) {
   
printf("Connect failed: %s\n"maxdb_connect_error());
   exit();
}

if (!
$maxdb->query("SELECT xxx FROM hotel.city")) {
   
printf("Errormessage: %s\n"$maxdb->error);
}

/* close connection */
$maxdb->close();
?>

Example #2 Stile procedurale

<?php
$link 
maxdb_connect("localhost""MONA""RED""DEMODB");

/* check connection */
if (maxdb_connect_errno()) {
   
printf("Connect failed: %s\n"maxdb_connect_error());
   exit();
}

if (!
maxdb_query($link"SELECT xxx FROM hotel.city")) {
   
printf("Errormessgae: %s\n"maxdb_error($link));
}

/* close connection */
maxdb_close($link);
?>

Il precedente esempio visualizzerĂ  qualcosa simile a:

PHP Warning:  maxdb_query(): -4005 POS(8) Unknown column name:XXX [42000]
Errormessgae: POS(8) Unknown column name:XXX
