How can you compare table column after update and before
update?

Answer Posted / mahesh vasudevan

If you mean a new column has been added to an existing table
or data been updated to an existing table data. I am not
sure on this question. Let me assume that you are talking
about data. Any update that takes place will have two
records logged -one is prior to update and another is after
update and these information goes to Logs. Logs are used
while recovery process for forward and point in time recovery.

and you can make an SQL query for "Union" - "Intersection"
operation to find the differences.
