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);
  }
}
?>
