mysql - 我如何编写查询来提取这样的结果？姓氏，性别计数

Question

在此处查看所需的结果

到目前为止，我所拥有的是基于以下查询的结果

...这不是很接近我需要的

SELECT
P.NAME_LAST,    
COUNT(P.NAME_LAST),    
P_SEX_DISP = UAR_GET_CODE_DISPLAY(P.SEX_CD),    
COUNT(P.SEX_CD)
FROM
    PERSON P
GROUP BY
P.NAME_LAST    
ORDER BY P.NAME_LAST ASC

Answer 1

您可以使用如下聚合：

select name_last,
    sum(sex_cd = 'male'),
    sum(sex_cd = 'female'),
    sum(sex_cd not in ('male','female')),
    count(*)
from person
group by name_last
order by name_last asc
