例如,你在utf8下设置某一字段的类型为TINYTEXT, 这中字段类型最大可以容纳255字节,三个字节一个字符的情况下可以容纳85个字符,四个字节一个字符的情况下只能容纳63个字符,如果原表中的这个字段的值有一个或多个超过了63个字符,那么转换成utf8mb4字符编码时将转换失败,你必须先将TINYTEXT更改为TEXT等更高容量的...

对于mysql来说,在中国,我们通常选择的有utf8和gbk,但是在MySQL5.5版本之后,开始支持utf8mb4字符集,这里就浅析一下utf8和utf8mb4的区别。 首先说一下utf8mb4是utf8的一个超集,它完全兼容utf8字符集。以往mysql里面的utf8字符集的一个字符最多只有3个字节,只支持bmp这部分的unicode编码区,而utf8mb4则扩展到...

关于utf8不支持emoji是因为emoji是用4个字节存储的字符,而mysql的utf8只能存储1-3个字节的字符。那就存不了呗 需要更改的地方: (1)Mysql服务器client,mysql,mysqld中需要显式指定字符集为utf8mb4 (2)在(1)的服务器上创建的db,需要为utf8mb4字符集,COLLATE为utf8mb4_unicode_ci 或 utf8mb4_general_ci...
