maxdb_error

(PECL maxdb:1.0-7.6.00.38)

maxdb_errorReturns a string description of the last error

Opis

Procedural style:

string maxdb_error ( resource $link )

Object oriented style (property)

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.

Zwracane wartości

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

Przykłady

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);
?>

Powyższy przykład wyświetli coś podobnego do:

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