I have a timestamp in a mysql table with attribute "ON UPDATE CURRENT_TIMESTAMP". Is there a way to manually disable updating the timestamp on a special occasion? (eg: updating the entry to revise a blog post, but not to re-date it)
You can manually set the value of the column to its current value in the update command:
UPDATE table SET x=y, timestampColumn=timestampColumn WHERE a=b;
If you don't set the value in the query, it will be updated to the current timestamp as per the table definition.
