Track the row change time

It is always useful to know when a row has been changed, this could be needed to extract some statistics regarding the table growth or at which specific time users are inserting or updating rows into the table (not deleting or selecting a row).

To test the tip below, you should create your table with the ROWDEPENDENCIES option.
More details about this option can be found below :

“ROWDEPENDENCIES Specify ROWDEPENDENCIES if you want to enable row-level dependency tracking. This setting is useful primarily to allow for parallel propagation in replication environments. It increases the size of each row by 6 bytes.”
