mysqli_stmt_execute

(PHP 5)mysqli_stmt_execute

(no version information, 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):class mysqli_stmt {

bool execute (void)

}

- The mysqli_stmt_execute() function executes a query that has been previously

prepared using the mysqli_prepare() function represented by the

stmt object. 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.

Замечание:

When using mysqli_stmt_execute(), the mysqli_stmt_fetch()

function must be used to fetch the data prior to performing any additional queries.

Возвращаемые значения

- Возвращает TRUE в случае успешного завершения или FALSE в случае возникновения ошибки.

/* 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();

?>

Пример 2. Procedural style

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';

/* 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");
