Sequence update not as expected when table column with an ON UPDATE CURRENT_TIMESTAMP clause

[ShineYang]

updateTime datetime DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP
The "updateTime" column can not automatically updated to the current timestamp when I use sequence update.
But everything went well with db.update(Table)
