Loop through all tables and detect changed rows using checksum or hashbytes All the tables have an extra row called checksum which is stored by doing INSERT INTO example_table VALUES ('a','b', BINARY_CHECKSUM('a','b')).

Suppose someone change a row value, obviously the checksum will change, and when I run Select CHECKSUM_AGG(*) FROM example_table, that value will differ from the stored checksum.
How can I detect, looping through all tables, what row or table was changed?
Can I do this with a Stored Procedure? This is an SQL SERVER database.
select * 
from table 
where BINARY_CHECKSUM('a','b') &lt;&gt; checksumCol 


But if they can change a or b they can change the checksumCol
