我正在尝试将包含 scandic 字母的网址插入到我的数据库中,例如:
ÄÖäöÅå
我正在使用:
- Opensuse 13.2 64 位 Linux 和 MariaDB。
- MySQL服务器版本:5.5.44-MariaDB openSUSE包
- PHP 版本为 5.4.20
当我尝试插入时,我收到此错误消息:
Incorrect string value: '\xC4HK\xD6.
此查询确认字符集和排序规则设置正确:
if (mysql_query("SET NAMES utf8mb4 COLLATE utf8mb4_unicode_ci")) {
echo "Character set OK !";
}
我的 MySQL 查询适用于除包含 scandic 字母的 URL 之外的所有内容:
if (mysql_query("INSERT INTO `table` (`address`) VALUES ('$URL')")){
$insertCount++;
echo "<br> insertcount = ".$insertCount."<br>";
} else {
echo "MySQLerror = ".mysql_error()."<br>"; // Show MySQLerror
这是来自 MariaDB 的 MySQL 信息,显示所有内容都设置为 utf8mb4
:

@Rick James:这是我得到的:
MariaDB [db]> SHOW CREATE TABLE table;
+--------+------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+
| Table | Create Table |
+--------+------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+

PRIMARY KEY (<code>addr</code>),
UNIQUE KEY <code>addr</code> (<code>addr</code>)
) ENGINE=MyISAM DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci COMMENT='List' |

1 row in set (0,00 sec)
MariaDB [db]>
最佳答案
试试这个
验证存储数据的表是否具有 utf8 字符集:
SELECT
`tables`.`TABLE_NAME`,
`collations`.`character_set_name`
FROM
`information_schema`.`TABLES` AS `tables`,
`information_schema`.`COLLATION_CHARACTER_SET_APPLICABILITY` AS `collations`
WHERE
`tables`.`table_schema` = DATABASE()
AND `collations`.`collation_name` = `tables`.`table_collation`
;
检查你的数据库设置:
show variables like '%colla%';
show variables like '%charac%';
把utf-8改成utf8_general_ci
ALTER TABLE tablename CONVERT TO CHARACTER SET utf8 COLLATE utf8_unicode_ci;
