协助 VB.net 查询

Question

这是我当前的查询：

select No,
       (select count(no) from textvote group by no) /
       (select count(no) from textvote where no like '%Ginoo%')
from textvote

Table: 文字投票

No      Sender
Ginoo 1 9307895654
Ginoo 1 9566551234
Ginoo 1 9232235643
Ginoo 2 9225557878

这一定是结果：

No      Total
Ginoo 1 75%
Ginoo 2 25%

Answer 1

这是你的想法吗：

SELECT no,
       CONCAT(CAST(100*count(*) /
                   (select count(*) from textvote where no like '%Ginoo%') AS CHAR(50)), '%') AS Total
FROM textvote
WHERE no LIKE '%Ginoo%'
GROUP BY no

此查询在下面的演示中工作正常：
