你如何让MySQL不将非ASCII视为ASCII？

Question

样本表：

CREATE TABLE test (name varchar(32)) ENGINE=InnoDB DEFAULT CHARSET=utf8;
INSERT INTO test VALUES ('adam');
INSERT INTO test VALUES ('ádam');

问题查询：

SELECT name FROM test WHERE username='ádam';
+----------+
| name     |
+----------+
| adam     |
| ádam     |
+----------+

如何让MySQL搜索用户输入完全而不是隐式地将其音译为ASCII？

Answer 1

mysql> SELECT name FROM test WHERE CONVERT(name USING BINARY) = 'ádam';

+-------+
| name  |
+-------+
| ádam  |
+-------+
