Description

Object-oriented style

public void mysqli_stmt::data_seek(int $offset)

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.

Parameters

offset

Must be between zero and the total number of rows minus one (0.. mysqli_stmt_num_rows - 1).

Return Values

No value is returned.

Examples

Example #1 Object-oriented style

<?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 Procedural style

<?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);

The above examples will output:

City: Benin City  Countrycode: NGA
