Prozeduraler Stil

bool mysqli_stmt_fetch ( mysqli_stmt `$stmt` )

Fetch the result from a prepared statement into the variables bound by mysqli_stmt_bind_result().

> Hinweis: Note that all columns must be bound by the application before calling mysqli_stmt_fetch().

> Hinweis: Data are transferred unbuffered without calling mysqli_stmt_store_result() which can decrease performance (but reduces memory cost).

### Parameter-Liste

`stmt`

  Nur bei prozeduralem Aufruf: ein von mysqli_stmt_init() zurückgegebens Statementobjekt.

### Rückgabewerte

Rückgabewerte
Value | Description
--- | ---
`TRUE` | Success. Data has been fetched
`FALSE` | Error occurred
`NULL` | No more rows/data exists or data truncation occurred

### Beispiele

exit();
}
$query = "SELECT Name, CountryCode FROM City ORDER by ID DESC LIMIT 150,5";
if ($stmt = $mysqli->prepare($query)) {
/* execute statement */
$stmt->execute();
/* bind result variables */
$stmt->bind_result($name, $code);
/* fetch values */
while ($stmt->fetch()) {
printf ("%s (%s)\n", $name, $code);
}
