Generally while updating rows in table we also update te
sourcr by which the rows were update( like program id)
also upadate date etc.
we can retrive the records having timestamp of the time the
rows were updated or the program name which was used to
update the table

Use the below query to fetch first 100 rows among 1000 rows ,
select * from table order by column desc fetch first 100 rows
column is either timestamp or id
so the above query gives recent 100 updated rows.
