Ich bin auf MySQL 5.5.21 und versuche, das Smiley-Zeichen '\ xF0 \ x9F \ x98 \ x8A' einzufügen. Aber für das Leben von mir kann ich nicht herausfinden, wie es geht.
Nach verschiedenen Foren, die ich gelesen habe, ist es möglich. Aber wenn ich es versuche, werden die Daten einfach abgeschnitten.
mysql> INSERT INTO hour ( `title`, `content`, `guid` , `published` , `lang` , `type` ,
`indegree` , `lon` , `lat` , `state` , `country` , `hour` )
VALUES ( "title" , "content 😊 content" , "guid" , 1, 1,
"WEBLOG", 1, 1, 1, "state" , "country" , 1 );
Query OK, 1 row affected, 2 warnings (0.00 sec)
mysql> show warnings;

mysql> select * from hour where id = 687302;
+--------+-------+----------+------+---------------------+

+--------+-------+----------+------+---------------------+
1 row in set (0.00 sec)
Aber meine Tabellendefinition ist wie folgt.
CREATE TABLE `hour` (
`id` bigint(20) NOT NULL AUTO_INCREMENT,
`title` varchar(255) CHARACTER SET utf8 NOT NULL,
`content` text CHARACTER SET utf8 NOT NULL,
`guid` varchar(255) CHARACTER SET utf8 NOT NULL,
`published` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
`lang` tinyint(3) unsigned NOT NULL,
`type` enum('WEBLOG','MICROBLOG') CHARACTER SET utf8 DEFAULT NULL,
`indegree` int(4) unsigned NOT NULL,
`lon` float DEFAULT NULL,
`lat` float DEFAULT NULL,
`state` varchar(50) CHARACTER SET utf8 DEFAULT '',
`country` varchar(50) CHARACTER SET utf8 DEFAULT '',
`hour` int(2) DEFAULT NULL,
`gender` enum('MALE','FEMALE') CHARACTER SET utf8 DEFAULT NULL,
`time_zone` varchar(45) CHARACTER SET utf8 DEFAULT NULL,
PRIMARY KEY (`id`)
) ENGINE=MEMORY AUTO_INCREMENT=687560 DEFAULT CHARSET=utf8mb4 KEY_BLOCK_SIZE=288
Man kann sehen, dass ich CHARSET = utf8mb4 benutze. Behebt dies sicherlich Probleme bei der Verwendung von Mehrbyte-Zeichen?
Ok, also habe ich nicht bemerkt:
`content` text CHARACTER SET utf8 NOT NULL,
Ich habe das jetzt korrigiert, bekomme aber immer noch irre Ergebnisse.

`id` bigint(20) NOT NULL AUTO_INCREMENT,
