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.

Example

Příklad 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();
?>

Příklad 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
