maxdb_error -- maxdb->error — Returns a string description of the last error
Prozeduraler Stil
Objektorientierter Stil
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.
A string that describes the error. An empty string if no error occurred.
Beispiel #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();
?>
Beispiel #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);
?>
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
