maxdb_error

maxdb::error

(PECL maxdb >= 1.0)

maxdb_error -- maxdb::error — Returns a string description of the last error

Description

Procedural style

maxdb_error ( resource $link ) : string

Object oriented style

stringmaxdb->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 occurred, this function will return an empty string.

Return Values

A string that describes the error. An empty string if 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("Errormessage: %s\n", $maxdb->error);
}

/* 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($link, "SELECT xxx FROM hotel.city")) {
   printf("Errormessgae: %s\n", maxdb_error($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
