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.

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

## Example

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
