mysqli_stmt::executemysqli_stmt_executeExecutes a prepared Query
Description
Object oriented stylebool mysqli_stmt::execute();
Procedural stylebool mysqli_stmt_execute(mysqli_stmt stmt);
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.Note
When using mysqli_stmt_execute, the mysqli_stmt_fetch function must be used to fetch the data prior to performing any additional queries.
Parameters
stmt-
Procedural style only: A statement identifier returned by
mysqli_stmt_init.
Return Values
Returns TRUE on success or FALSE on failure.
Examples
Example 20.156. 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();
?>
Example 20.157. 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);
?>
The above examples will output:
Stuttgart (DEU,Baden-Wuerttemberg) Bordeaux (FRA,Aquitaine)
