第一种：

select name, 

CHAR(INTERVAL(CONV(HEX(left(CONVERT(name USING GBK),1)),16,10),

0xB0A1,0xB0C5,0xB2C1,0xB4EE,0xB6EA,0xB7A2,0xB8C1,0xB9FE,

0xBBF7,0xBBF7,0xBFA6,0xC0AC,0xC2E8,0xC4C3,0xC5B6,0xC5BE,

0xC6DA,0xC8BB,0xC8F6,0xCBFA,0xCDDA,0xCDDA,0xCDDA,0xCEF4,

0xD1B9,0xD4D1) + 64) as PY

from table

 

第二种：

select name,

 ELT(INTERVAL(CONV(HEX(left(CONVERT(name USING GBK),1)),16,10),

 0xB0A1,0xB0C5,0xB2C1,0xB4EE,0xB6EA,0xB7A2,0xB8C1,0xB9FE,0xBBF7,0xBFA6,0xC0AC,0xC2E8,0xC4C3,0xC5B6,

  0xC5BE,0xC6DA,0xC8BB,0xC8F6,0xCBFA,0xCDDA,0xCEF4,0xD1B9,0xD4D1),

 'A','B','C','D','E','F','G','H','J','K','L','M','N','O','P','Q',  'R','S','T','W','X','Y','Z') as PY 

 from table

 

备注：

1> 第一种方法似乎需要mysql 5.1版本。

1> mysql中文一般都是utf-8编码，上述16进制为GBK编码范围，因此需要转换编码：convert(name using GBK)
