MySQL output 十六进制字符串为 UTF-8

Question

This works UTF8

create temporary table test (x char(1) not null) charset=utf8;
insert into test select x'c3a9';
select hex(x), x from test;
drop table test;

outputs

+--------+---+
| hex(x) | x |
+--------+---+
| C3A9   | é | 
+--------+---+

But this uses the default charset which is not utf8

SELECT x'c3a9';

How can I change the above one-liner to output UTF-8 é instead of é ?

Answer 1

SELECT CONVERT(x'c3a9' USING utf8)

should work. See 11.10. Cast Functions and Operator .
