how to copy from fields to other fields

    I have a table which has a datetime field for when a row in this one table
    (Ticket) was created. This is for trouble tickets for a help desk. After a
    ticket has been created, any additions to that ticket are recorded in
    another table called History. There could be several additions, thus the
    splitting up into a one-to-many relationship.


    In order to meet the boss's request, I recently added a LastModified field
    to the Ticket table. I have included code in my ASP which will fill that
    field with the date when a new ticket is created, and then when new data is
    added later, will update that field. The problem is that for all existing
    tickets, that field is empty. I'd like to run a SQL statement which will
    copy the entry date (but only the date, not the time) from the original
    timestamp field of each existing ticket, and then go back and see if there
    are any updates in the History table for each ticket, and if so, take the
    MAX value for the Timestamp field in that table, and copy it over, again,
    just the date, not the whole timestamp.

    I realize that you may wonder why I don't just use the MAX(TimeStamp) from
    my history table as my lastmodified, but I had lots of trouble with this.
    This way works, and I just need to find a way to keep from having nulls in
    existing tickets.
