问题
I am regular user of MS-SQL but now working on a project which has mysql as a back-end.
Please tell me that is there exists such a inserted/Deleted tables (Magic tables) in mysql which I can use inside trigger or in normal queries.
回答1:
They are called NEW
and OLD
in MySQL.
NEW
is the new record to be inserted or the updated data.
OLD
is the deleted record, or the old data before an update.
See the documentation for creating a trigger here: http://dev.mysql.com/doc/refman/5.0/en/create-trigger.html
