arjunsuresh,Thanks for your reply!
I convert the qa_eventlog table to utf8mb4 encoding and restart the database.Since I do n’t know if the operation is correct, I paste the printed information
CREATE TABLE `qa_eventlog` (
`datetime` datetime NOT NULL,
`ipaddress` varchar(45) CHARACTER SET ascii DEFAULT NULL,
`userid` int(10) unsigned DEFAULT NULL,
`handle` varchar(20) CHARACTER SET utf8 DEFAULT NULL,
`cookieid` bigint(20) unsigned DEFAULT NULL,
`event` varchar(20) CHARACTER SET ascii NOT NULL,
`params` varchar(800) CHARACTER SET utf8 NOT NULL,
KEY `datetime` (`datetime`),
KEY `ipaddress` (`ipaddress`),
KEY `userid` (`userid`),
KEY `event` (`event`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci
The warning will still appear wrong. The problem does not seem to be resolved
