# mysqli_data_seek

(PHP 5)

mysqli_data_seek

(no version information, might be only in CVS)

result->data_seek -- Adjusts the result pointer to an arbitary row in the result

## Description

Procedural style:

bool mysqli_data_seek ( object result, int offset)

Object oriented style (method):

class result {
bool data_seek ( int offset)
}

The mysqli_data_seek() function seeks to an arbitrary result pointer specified by the `offset` in the result set represented by `result`. The `offset` parameter must be between zero and the total number of rows minus one (0..mysqli_num_rows() - 1).

> Anmerkung: This function can only be used with unbuffered results attained from the use of the mysqli_store_result() or mysqli_query() functions.

## Return values

Gibt bei Erfolg `TRUE` zurück, im Fehlerfall `FALSE`.

mysqli_store_result(), mysqli_fetch_row(), mysqli_num_rows().

## Example

Beispiel 1. Object oriented style
`<?php /* Open a connection */ $mysqli = new mysqli("localhost", "my_user", "my_password", "world"); /* check connection */ if (mysqli_connect_errno()) { printf("Connect failed: %s\n", mysqli_connect_error()); exit(); } $query = "SELECT Name, CountryCode FROM City ORDER BY Name"; if ($result = $mysqli->query( $query)) { /* seek to row no. 400 */ $result->data_seek(399); /* fetch row */ $row = $result->fetch_row(); printf ("City: %s Countrycode: %s\n", $row[0], $row[1]); /* free result set*/ $result->close(); } /* close connection */ $mysqli->close(); ?>`

Beispiel 2. Procedural style
`<?php /* Open a connection */ $link = mysqli_connect("localhost", "my_user", "my_password", "world"); /* check connection */ if (!$link) { printf("Connect failed: %s\n", mysqli_connect_error()); exit(); } $query = "SELECT Name, CountryCode FROM City ORDER BY Name"; if ($result = mysqli_query($link, $query)) { /* seek to row no. 400 */ mysqli_data_seek($result, 399); /* fetch row */ $row = mysqli_fetch_row($result); printf ("City: %s Countrycode: %s\n", $row[0], $row[1]); /* free result set*/ mysqli_free_result($result); } /* close connection */ mysqli_close($link); ?>`

The above examples would produce the following output:

    City: Benin City  Countrycode: NGA
