maxdb_stmt_fetch -- maxdb_stmt::fetch — Fetch results from a prepared statement into the bound variables
过程化风格
面向对象风格
maxdb_stmt_fetch() returns row data using the variables bound by maxdb_stmt_bind_result().
Note:
Note that all columns must be bound by the application before calling maxdb_stmt_fetch().
| Value | Description |
|---|---|
| TRUE | Success. Data has been fetched |
| FALSE | Error occured |
| NULL | No more rows/data exists |
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();
}
$query = "SELECT zip, name FROM hotel.city ORDER by name";
if ($stmt = $maxdb->prepare($query)) {
/* execute statement */
$stmt->execute();
/* bind result variables */
$stmt->bind_result($name, $code);
/* fetch values */
while ($stmt->fetch()) {
printf ("%s (%s)\n", $name, $code);
}
/* close statement */
$stmt->close();
}
/* 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();
}
$query = "SELECT zip, name FROM hotel.city ORDER by name";
if ($stmt = maxdb_prepare($link, $query)) {
/* execute statement */
maxdb_stmt_execute($stmt);
/* bind result variables */
maxdb_stmt_bind_result($stmt, $name, $code);
/* fetch values */
while (maxdb_stmt_fetch($stmt)) {
printf ("%s (%s)\n", $name, $code);
}
/* close statement */
maxdb_stmt_close($stmt);
}
/* close connection */
maxdb_close($link);
?>
