Hello
Following is the description of the problem being faced.

Problem:
The first timestamp column in a table is set to current date-time value as soon as we 
update one or more columns in the table.

Example:

The guest information is stored in a table named GUEST. The schema for it is as below.

create table guest (guestID int, arrivalDate timestamp, departureDate timestamp, 
status char(1));

Above table is populated using following queries.

insert into guest values (1, '2002-09-30',  '2002-10-14', 'Y');
insert into guest values (2, '2002-09-20',  '2002-10-01', 'Y');
insert into guest values (3, '2002-09-15',  '2002-09-25', 'Y');
insert into guest values (4, '2002-09-12',  '2002-09-20', 'Y');


If we use following query to update the status from Y to N, then arrivalDate column is 
set to CURRENT(system) date-time value.

update guest set status = 'N';

Does anybody have any information on this issue?

Thanx in advance.
