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);
}
}
?>
