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 occured, this function will return an empty string.

Valor Retornado

/* 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);

$maxdb->close();

<?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);
?>

O exemplo acima irá imprimir algo similar a:

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