"Mysql 授权仅限于一天中的特定时间"

Question

I'd like to know if it is possible in mysql to grant select permission to user but only within specific hours of a day.

I have created several views and new user and want to let them browse those mysql views only (for example) between 10pm and 11pm.

Answer 1

Edit the view criteria to be:

WHERE ... (previous criteria)
AND (CURRENT_USER() != 'bob@%' OR CURTIME() BETWEEN '22:00' AND '23:00')

This restricts the bob user on these times, otherwise no results are returned in the view.
