CONCAT隨着ROLLUP

Question

我想同時使用匯總的姓氏和名字列組合在一起，但它似乎相同的姓氏複製到每一個姓：

SELECT IFNULL(CONCAT(u.firstname, ' ', u.lastname),'Total Projects') AS Name, count(DISTINCT(p.id)) AS Total 
FROM projects p 
INNER JOIN users u ON p.creator_fk = u.id 
GROUP BY Name WITH ROLLUP; 

所以我最終的東西，如：

Name   | Total 

John Smith  | 10 
Sarah Smith | 25 
Tracy Smith | 5 
Total Projects | 40 

Answer 1

按我的理解

SELECT IFNULL(name,'Total Projects') AS Name, count(DISTINCT(id)) AS Total 
from (select CONCAT(u.firstname,' ', u.lastname) as name,p.id 
    FROM projects p INNER JOIN users u ON p.creator_fk = u.id) as p GROUP BY name WITH ROLLUP;
