1.今天小编很开心获得了一个如何使用mysql数据库来获字段字符串中文首字母的sql语句下面分享给大家:

SELECT t.b_name,
ELT(INTERVAL(CONV(HEX(LEFT(CONVERT(t.b_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 cz_brand t WHERE LEFT(t.b_name,1) NOT IN (‘A’,‘B’,‘C’,‘D’,‘E’,‘F’,‘G’,‘H’,‘J’,‘K’,‘L’,‘M’,‘N’,‘O’,‘P’,
‘Q’,‘R’,‘S’,‘T’,‘W’,‘X’,‘Y’,‘Z’)
