I understand how a timestamp column automatically changes when there is a change in a data row. Is it possible to limit the update to changes in 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" -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe: http://lists.mysql.com/mysql
