# maxdb_errno

(PECL)

maxdb_errno

(no version information, might be only in CVS)

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

## Description

Procedural style:

int maxdb_errno ( resource link )

Object oriented style (property):

class maxdb {
int errno
}

The maxdb_errno() function will return the last error code for the most recent MaxDB function call that can succeed or fail with respect to the database link defined by the link parameter. If no errors have occured, this function will return zero.

## Return values

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

## See also

maxdb_connect_errno(), maxdb_connect_error(), maxdb_error(), maxdb_sqlstate()

## Example

Пример 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(); ?>`

Пример 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
