Re: time stamp specific to columns

I think you'd have to do that with a trigger.

I understand how a timestamp column automatically changes when there is a

particular columns? I have a table where I care about changes in any of
four different columns, but I don¹t care about changes in other columns or
added columns.

Is there a command that says ³update the time stamp if and only if there
is a change in columns a, b,c, or d"
