How can we manage the history of changed rows in the database. I have some
idea but not yet implemented. By using triggers to make a copy of the row
being changed to the another table in the same db. Is there any way to only

You are expecting an awfull lot from mysql to remember data that it never

Changing the column size will not bring back the data.
