INNER JOIN tbl_campaign_played cp ON cp.CampaignCode = cm.campaignCode

 Male        1       50%
Female       1       50%

I want to know , how we will percentage of each row

Answer 1

based on your output just sample query

declare  @t table (gender varchar(10),people int)

insert into @t (gender,people)values('male',1)
insert into @t (gender,people)values('female',1)


Select gender,people, CONVERT(VARCHAR(10),(Count(people)* 100 / (Select Count(*) From @t)))+'%' as Score
From @t
Group By gender,people

you can modify the code in you query as per my assumption

SELECT 
  (SELECT gender    FROM tbl_gender WHERE genderCode = u.genderCode) AS gender,
  CONVERT(VARCHAR(10),COUNT(cp.UserID)/(Select Count(*) From tbl_campaign_played WHERE campaignCode = cm.campaignCode ))) AS people
FROM tbl_campaign_master cm

INNER JOIN tbl_campaign_played cp ON cp.CampaignCode = cm.campaignCode
INNER JOIN tbl_users u ON cp.UserID = u.userId

WHERE cm.campaignCode = 'CM00000179'
GROUP BY u.genderCode
