Question

I have the following two table in SQL server 2005 DB

2- “UserInfomration” —> ( ID (auto) , Name , Gender ( bit ) )

1- “Competitors” —> ( Id (auto) , UserID ( FK from UserInformation.ID ) , Status ( tinyint)

i want to make a stored procedure that return data as follow

Status – Male count – Female Count

     1                  45                    15

     2                 10                    50

     3                 20                    60

So could anyone share with me the best solution to do that

My Solution was the following :

SELECT  
        Competitors.Status, 
        COUNT(Competitors.ID) AS MaleCount , 
        (
            SELECT Count(C.ID) 
            FROM Competitors as C , UserInfomration as UI
            WHERE UI.UserID = C.UserID  AND UI.UserGender = 0 AND C.Status = Competitors.Status  
        ) as FemaleCount ,
        (MaleCount + FemaleCount) as total
FROM     
        UserInfomration LEFT OUTER JOIN
               Competitors ON UserInfomration.UserID = ISEFCompetitors.UserID
GROUP BY Competitors.Status, UserInfomration.UserGender
HAVING  (UserInfomration.UserGender = 1)
ORDER BY Competitors.Status

Thanks in advance for your expected cooperation

Answer 1

You can try something like this

SELECT  c.Status,
        SUM(CASE WHEN u.Gender = 0 THEN 1 ELSE 0 END) Male, --assuming 0 is male
        SUM(CASE WHEN u.Gender = 1 THEN 1 ELSE 0 END) Female --assuming 1 is female
FROm    Competitors c INNER JOIN
        UserInfomration u ON c.UserID = u.ID
GROUP BY c.Status
