mysql字段排序数字在字母前面，字母也要按首字母排序

如果是oracle 的话，创建下面的函数，调用函数做视图可以实现你要的效果

CREATE OR REPLACE FUNCTION F_TRANS_PINYIN_CAPITAL(P_NAME IN VARCHAR2) RETURN VARCHAR2 AS

V_COMPARE VARCHAR2(100)

V_RETURN VARCHAR2(4000)

FUNCTION F_NLSSORT(P_WORD IN VARCHAR2) RETURN VARCHAR2 AS

BEGIN

RETURN NLSSORT(P_WORD, 'NLS_SORT=SCHINESE_PINYIN_M')

END

BEGIN

FOR I IN 1..LENGTH(P_NAME) LOOP

V_COMPARE := F_NLSSORT(SUBSTR(P_NAME, I, 1))

IF V_COMPARE >= F_NLSSORT(' 吖 ') AND V_COMPARE <= F_NLSSORT('骜 ') THEN

V_RETURN := V_RETURN || 'a'

ELSIF V_COMPARE >= F_NLSSORT('八 ') AND V_COMPARE <= F_NLSSORT('簿 ') THEN

V_RETURN := V_RETURN || 'b'

ELSIF V_COMPARE >= F_NLSSORT('嚓 ') AND V_COMPARE <= F_NLSSORT('错 ') THEN

V_RETURN := V_RETURN || 'c'

ELSIF V_COMPARE >= F_NLSSORT('咑 ') AND V_COMPARE <= F_NLSSORT('鵽 ') THEN

V_RETURN := V_RETURN || 'd'

V_RETURN := V_RETURN || 'j'

ELSIF V_COMPARE >= F_NLSSORT('咔 ') AND V_COMPARE <= F_NLSSORT('穒 ') THEN

V_RETURN := V_RETURN || 'p'

ELSIF V_COMPARE >= F_NLSSORT('七 ') AND V_COMPARE <= F_NLSSORT('裠 ') THEN

V_RETURN := V_RETURN || 'q'

ELSIF V_COMPARE >= F_NLSSORT('亽 ') AND V_COMPARE <= F_NLSSORT('鶸 ') THEN

V_RETURN := V_RETURN || 'r'

ELSIF V_COMPARE >= F_NLSSORT('仨 ') AND V_COMPARE <= F_NLSSORT('蜶 ') THEN

V_RETURN := V_RETURN || 's'

ELSIF V_COMPARE >= F_NLSSORT('侤 ') AND V_COMPARE <= F_NLSSORT('箨 ') THEN

END IF

END LOOP

RETURN V_RETURN

创建表：

create table test

(str varchar(10))

insert into test values ('A1')

insert into test values ('A2')

insert into test values ('A10')

insert into test values ('A11')

insert into test values ('B1')

insert into test values ('B2')

insert into test values ('B10')

insert into test values ('B11')

执行：

select * from test order by left(str,1),convert(substr(str,2,length(str)-1),SIGNED)

结果：

SELECT name FROM `user` ORDER BY CONVERT( name USING gbk ) ASC

直接就是按汉字首个字的首字母排序，自动都会分组了啊。
