# maxdb_error

(PECL)

maxdb_error -- Returns a string description of the last error

## Description

Procedural style:

string maxdb_error ( resource link )

Object oriented style (property)

class 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.

## Return values

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

## See also

maxdb_connect_errno(), maxdb_connect_error(), maxdb_errno(), maxdb_sqlstate()

## Example

Przykład 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(); ?>`

Przykład 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 examples would produce the following output:

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