I am running MySql 4.1.6 in FC-4 Linux amd it is a huge learning
exercise for me!
I am using O'Reilly's MYSQL Cookbook, have gone through numerous
pages of the "reference manual" and stuff on Google but still can get
the proper commands and syntax to alter the following table "T1."
I would like "Createdate" to show the date the record was crated and
remain that.
I would like "Workdate" to show the current date unless changed by the
user and remain there until the next time there was a change in the
record.
It would be good if these dates would come up immediately without
re-opening the table as it seems to do now after my best efforts
[which have never been completely successful] although that may well
be a problem with "Navicat" which I am using as a GUI? My efforts at
setting up the table have all been via the mysql command line.
If someone could provide an example of a working "ALTER TABLE T1
................................." command it would be greatly
appreciated.
Thank you.

You have Createdate and Workdate swapped.
The first timestamp gets updated on every update to the record.
