Question

有人知道为什么会失败吗？

我已经创建了一个带有char3主键的utf-8表，并且在使用MySQL Workbench向其中插入记录时，它无法区分A和Ä

我们正在使用MySQL 5.1.73和Workbench 6.3.10

CREATE TABLE `test` (
  `citycode` char(3) NOT NULL,
    PRIMARY KEY (`citycode`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8;

INSERT INTO `test` (`citycode`) VALUES ('JLA');
INSERT INTO `test` (`citycode`) VALUES ('JLÄ');

Operation failed: There was an error while applying the SQL script to the database.
Executing:
INSERT INTO `trains4_copy`.`test` (`citycode`) VALUES ('JLA');
INSERT INTO `trains4_copy`.`test` (`citycode`) VALUES ('JLÄ');

ERROR 1062: 1062: Duplicate entry 'JLÄ' for key 'PRIMARY'
SQL Statement:
INSERT INTO `trains4_copy`.`test` (`citycode`) VALUES ('JLÄ')

请参阅此link，将这些类型的字符集存储为二进制。

var interval; // initialize at top

interval = setInterval(Down,myVar); // replace with this in `if(gameStarted)` loop

clearInterval(interval ) // clear interval on confirm("GAME OVER!")

尝试dbfiddle。
