[SQLObject] Having a modified column filled in automagically...

[Sam's L. <sam...@gm...>]

Hi...

I'd like to be able to create a timestamp column called "mtime" in some of
my columns.  This would hold a timestamp of when the row was last modified.

But I'd like the timestamp to be updated automatically whenever sqlobject
updates anything else in the row.

How can I do this?  I'd like a solution that is easy to add to any
table....maybe so easy that the table only has to have a column called mtime
and then everything happens without anything extra on my part.

Thanks
