stmt->execute()

(No version information available, might be only in CVS)

stmt->execute() — Executes a prepared Query

Description

Procedural style:

bool mysqli_stmt_execute ( mysqli_stmt $stmt )

Object oriented style (method):

mysqli_stmt

bool execute ( void )

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 appropiate 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

Geeft TRUE terug bij succes, FALSE indien er een fout is opgetreden.

    printf("Connect failed: %s\n", mysqli_connect_error());
    exit();

/* remove table */
$mysqli->query("DROP TABLE myCity");

/* close connection */
$mysqli->close();
?>

Example#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 */

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);
?>
