answer for that using LIMIT etc, but UPDATE dont have it.

Thanks in advance for your help.

Try this

UPDATE table SET notes="hi"
ORDER BY id DESC
LIMIT 10

As per Mysql docs, if there is a unique column, order by it DESC, and use LIMIT 10 to select last 10 records.

UPDATE [LOW_PRIORITY] [IGNORE] table_reference
        SET col_name1={expr1|DEFAULT} [, col_name2={expr2|DEFAULT}] ...
        [WHERE where_condition]
        [ORDER BY ...]
        [LIMIT row_count]
