fristPinyin : 此函数是将一个中文字符串的第一个汉字转成拼音字母
(例如:"中国人"->Z)
- CREATE FUNCTION `fristPinyin`(P_NAME VARCHAR(255)) RETURNS varchar(255) CHARSET utf8
- BEGIN
- DECLARE V_RETURN VARCHAR(255);
- SET V_RETURN = ELT(INTERVAL(CONV(HEX(left(CONVERT(P_NAME USING gbk),1)),16,10),
- 0xB0A1,0xB0C5,0xB2C1,0xB4EE,0xB6EA,0xB7A2,0xB8C1,0xB9FE,0xBBF7,
