mysql_data_seek -- Move internal result pointer


int mysql_data_seek (int result_identifier, int row_number)

Returns: true on success, false on failure.

mysql_data_seek() moves the internal row pointer of the MySQL result associated with the specified result identifier to point to the specified row number. The next call to mysql_fetch_row() would return that row.

Row_number starts at 0.

Example 1. MySQL data seek example

    $link = mysql_pconnect ("kron", "jutta", "geheim")
        or die ("Could not connect");

    mysql_select_db ("samp_db")
        or die ("Could not select database");

    $query = "SELECT last_name, first_name FROM friends";
    $result = mysql_query ($query)
        or die ("Query failed");

    # fetch rows in reverse order

    for ($i = mysql_num_rows ($result) - 1; $i >=0; $i--) {
        if (!mysql_data_seek ($result, $i)) {
            printf ("Cannot seek to row %d\n", $i);

        if(!($row = mysql_fetch_object ($result)))

        printf ("%s %s<BR>\n", $row->last_name, $row->first_name);

    mysql_free_result ($result);
