Beskrivelse

Procedural style

string maxdb_error ( resource $link )

Object oriented style

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.

Returnerings Værdier

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

Eksempler

Eksempel #1 Object oriented style

<?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();
?>

Eksempel #2 Procedural style

<?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);
?>

The above example will output something similar to:

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