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
例子 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();
?>

例子 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 |
