mysqli_stmt::data_seek -- mysqli_stmt_data_seek — Adjusts the result pointer to an arbitrary row in the buffered result
Stile orientato agli oggetti
Stile procedurale
This function moves the result set pointer of the buffered result set to
an arbitrary row specified by the offset
parameter.
This function works only on the buffered internal result set. mysqli_stmt_store_result() must be called prior to mysqli_stmt_data_seek().
stmt
Solo nello stile procedurale: un identificatore di statement restituito da mysqli_stmt_init().
offset
Must be between zero and the total number of rows minus one (0.. mysqli_stmt_num_rows() - 1).
Nessun valore viene restituito.
Example #1 Stile orientato agli oggetti
<?php
mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);
$mysqli = new mysqli("localhost", "my_user", "my_password", "world");
$query = "SELECT Name, CountryCode FROM City ORDER BY Name";
$stmt = $mysqli->prepare($query);
$stmt->execute();
$stmt->bind_result($name, $code);
$stmt->store_result();
/* seek to row no. 400 */
$stmt->data_seek(399);
$stmt->fetch();
printf("City: %s Countrycode: %s\n", $name, $code);
Example #2 Stile procedurale
<?php
mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);
$link = mysqli_connect("localhost", "my_user", "my_password", "world");
$query = "SELECT Name, CountryCode FROM City ORDER BY Name";
$stmt = mysqli_prepare($link, $query);
mysqli_stmt_execute($stmt);
mysqli_stmt_bind_result($stmt, $name, $code);
mysqli_stmt_store_result($stmt);
/* seek to row no. 400 */
mysqli_stmt_data_seek($stmt, 399);
mysqli_stmt_fetch($stmt);
printf("City: %s Countrycode: %s\n", $name, $code);

City: Benin City Countrycode: NGA
