I've encoutered strange problem when using sqlite_seek(). When I tried to move the pointer to the first row (#0) I got the fallowing error message: row 0 out of range. The workaround seems to be use of sqlite_rewind(). One can use the fallowing function instead of the original one: <?php function sqlite_data_seek($result, $numrow) { if ($numrow==0) { return sql_rewind($result); } else { return sql_seek($result, $numrow); } } ?>
