Re: updating records without changing timestamp fields
* Henning Heil the subject tells almost everything, I try to update records in a table and everytime I do this, the timestamp field ist set to now(). how can I keep the previously stored value for this field (there are values created before)? You can assign the current value to it: UPDATE table1 SET some_col = 5, other_col = test, timestamp_col = timestamp_col WHERE key_col = 123; -- Roger -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]
