I want to update only rows where equals '2003-06-10 11:15:00'
Is this formulation correct?
is really a DATETIME field.
Thanks.
In that case, you don't need DATE_FORMAT() at all. Just compare activity_date
to the datetime value directly.
You still haven't indicated what you

Any idea?
What do you mean by "is not valid"? The comparison doesn't work? The
correct value doesn't get stored into the row?
In any case, if activity_date really is a DATETIME column, you must
store valu
your date format is not correct. It should be activity_date = '2003-9-10

Hi, you can use a DateTime field, but it is possible to get duplicate
datetimes if you insert multiple queries fast enough.

Hi Alex,
I don't think your problem will solved by making the time columns to full
datetime columns as there is no
functions to subtract two datetime values directly.
But you can can keep the time columns and go on like this:

No. Since the string "now()" is not a valid date it is equivalent to 0,
so MySQL inserts the current date and time.

On my own mysql version :
Date TIMESTAMP default "now()",
Works correctly, the date is YY
Only the first timestamp is updated by MYSQL. Create two timestamp
fields. MySQL will maintain the first one. Set timestamp2 to null when
the record is created.
