string maxdb_error ( resource $link )

Objektorientierter Stil

string $maxdb->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.

R√ľckgabewerte

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

Beispiele

Beispiel #1 Objektorientierter Stil

<?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();
?>

Beispiel #2 Prozeduraler Stil

<?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);
?>

Das oben gezeigte Beispiel erzeugt eine ähnliche Ausgabe wie:

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