maxdb->errno — Returns the error code for the most recent function call

### Description

Procedural style:

int maxdb_errno ( resource `$link` )

Object oriented style (property):

maxdb
int$errno;

### Return Values

An error code value for the last call, if it failed. zero means no error occurred.

### Examples

Example#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("Errorcode: %d\n", $maxdb->errno);
}
/* close connection */
$maxdb->close();
?>`

Example#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("Errorcode: %d\n", maxdb_errno($link));
}
/* close connection */
maxdb_close($link);
?>`

The above examples would produce the following output:

    PHP Warning:  maxdb_query(): -4005 POS(8) Unknown column name:XXX [42000] <...>
    Errorcode: -4005
