maxdb_error — Returns a string description of the last error
Описание
Procedural style:
string maxdb_error
( resource $link
)
Object oriented style (property)
maxdb
string$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.
Возвращаемые значения
A string that describes the error. An empty string if no error occurred.

exit();
}
if (!$maxdb->query("SELECT xxx FROM hotel.city")) {
printf("Errormessage: %s\n", $maxdb->error);
}
/* close connection */
$maxdb->close();
?>
Пример #2 Procedural style

exit();
}
if (!maxdb_query($link, "SELECT xxx FROM hotel.city")) {
