maxdb_error (PECL) maxdb_error -- Returns a string description of the last error DescriptionProcedural 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
$maxdb = new maxdb("localhost", "MONA", "RED", "DEMODB");
if (maxdb_connect_errno()) {
printf("Connect failed: %s\n", maxdb_connect_error());
exit();
}
if (!$maxdb->query("SELECT xxx FROM hotel.city")) {
printf("Errormessage: %s\n", $maxdb->error);
}
$maxdb->close();
?>

例子 2. Procedural style |
<?php
$link = maxdb_connect("localhost", "MONA", "RED", "DEMODB");
if (maxdb_connect_errno()) {
printf("Connect failed: %s\n", maxdb_connect_error());
exit();
}
if (!maxdb_query($link, "SELECT xxx FROM hotel.city")) {
printf("Errormessgae: %s\n", maxdb_error($link));
}
maxdb_close($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 |
