PHP Dokumentation: Mysqli-stmt execute
12. Januar 2010 von werner
mysqli_stmt::execute
mysqli_stmt_execute
(PHP 5)
mysqli_stmt::execute — mysqli_stmt_execute — Executes a prepared Query
Beschreibung
Object oriented style (method):
Procedural style:
Executes a query that has been previously prepared using the mysqli_prepare() function. When executed any parameter markers which exist will automatically be replaced with the appropriate data.
If the statement is UPDATE, DELETE, or INSERT, the total number of affected rows can be determined by using the mysqli_stmt_affected_rows() function. Likewise, if the query yields a result set the mysqli_stmt_fetch() function is used.
Hinweis: When using mysqli_stmt_execute(), the mysqli_stmt_fetch() function must be used to fetch the data prior to performing any additional queries.
Parameter-Liste
- stmt
Nur bei prozeduralem Aufruf: ein vonmysqli_stmt_init() zurückgegebensStatementobjekt.
Rückgabewerte
Gibt bei Erfolg TRUE zurück. Im Fehlerfall wird FALSE zurückgegeben.
Beispiele
Beispiel #1 Object oriented style
<?php
$mysqli = new mysqli("localhost", "my_user", "my_password", "world");/* check connection */
if (mysqli_connect_errno()) {
printf("Connect failed: %s\n", mysqli_connect_error());
exit();
}$mysqli->query("CREATE TABLE myCity LIKE City");/* Prepare an insert statement */
$query = "INSERT INTO myCity (Name, CountryCode, District) VALUES (?,?,?)";
$stmt = $mysqli->prepare($query);$stmt->bind_param("sss", $val1, $val2, $val3);$val1 = 'Stuttgart';
$val2 = 'DEU';
$val3 = 'Baden-Wuerttemberg';/* Execute the statement */
$stmt->execute();$val1 = 'Bordeaux';
$val2 = 'FRA';
$val3 = 'Aquitaine';/* Execute the statement */
$stmt->execute();/* close statement */
$stmt->close();/* retrieve all rows from myCity */
$query = "SELECT Name, CountryCode, District FROM myCity";
if ($result = $mysqli->query($query)) {
while ($row = $result->fetch_row()) {
printf("%s (%s,%s)\n", $row[0], $row[1], $row[2]);
}
/* free result set */
$result->close();
}/* remove table */
$mysqli->query("DROP TABLE myCity");/* close connection */
$mysqli->close();
?>Beispiel #2 Procedural style
<?php
$link = mysqli_connect("localhost", "my_user", "my_password", "world");/* check connection */
if (mysqli_connect_errno()) {
printf("Connect failed: %s\n", mysqli_connect_error());
exit();
}mysqli_query($link, "CREATE TABLE myCity LIKE City");/* Prepare an insert statement */
$query = "INSERT INTO myCity (Name, CountryCode, District) VALUES (?,?,?)";
$stmt = mysqli_prepare($link, $query);mysqli_stmt_bind_param($stmt, "sss", $val1, $val2, $val3);$val1 = 'Stuttgart';
$val2 = 'DEU';
$val3 = 'Baden-Wuerttemberg';/* Execute the statement */
mysqli_stmt_execute($stmt);$val1 = 'Bordeaux';
$val2 = 'FRA';
$val3 = 'Aquitaine';/* Execute the statement */
mysqli_stmt_execute($stmt);/* close statement */
mysqli_stmt_close($stmt);/* retrieve all rows from myCity */
$query = "SELECT Name, CountryCode, District FROM myCity";
if ($result = mysqli_query($link, $query)) {
while ($row = mysqli_fetch_row($result)) {
printf("%s (%s,%s)\n", $row[0], $row[1], $row[2]);
}
/* free result set */
mysqli_free_result($result);
}/* remove table */
mysqli_query($link, "DROP TABLE myCity");/* close connection */
mysqli_close($link);
