计数mysql中的连接列

我想做this,但对于另一种情况却无法正常工作.
这是我的示例表：

编辑
我试过这个查询：
SELECT Date(Inspection_datetime), Model,
COUNT(DISTINCT(CONCAT(Range_sampling,Model,Line,Lot_no))) AS lot_qty,
IF(Status !='reject',1,0) AS accept,
IF(Status ='reject',1,0) AS reject
来自Inspection_report
GROUP BY Date(Inspection_datetime),模型
并得到如下结果：
Date(Inspection_datetime) Model lot_qty accept reject
2010-08-01 KD-G435UND 1 1 0
2010-08-01 kd-r411ed 1 0 1
2010-08-01 KW-TC800UND 1 1 0
2010-09-01 KD-G435UND 1 1 0
2010-09-01 kd-r411ed 2 0 1
2010-09-02 KD-G435UND 1 1 0
2010-10-01 KW-TC800UND 1 1 0
我想制作一张像这样的桌子：
Date lot_qty accept reject
2010-08-01 3 2 1 //count in same date become one
2010-09-01 3 1 1 //count in same date become one
2010-09-02 1 1 0
2010-10-01 1 1 0
这个查询几乎接近答案,但是我无法计算接受和拒绝的结果,然后在同一日期进行分组.
解决方法:
回答：
SELECT X.InsDate, SUM(X.lot_qty), SUM(X.accept), SUM(X.reject)
FROM
(SELECT
Date(Inspection_datetime) as InsDate,
Model,
COUNT(DISTINCT(CONCAT(Range_sampling,Model,Line,Lot_no))) AS lot_qty,
IF(Status !='reject',1,0) AS accept,
IF(Status ='reject',1,0) AS reject
FROM inspection_report
GROUP BY Date(Inspection_datetime), Model, Line, Range_sampling, Lot_no) X
GROUP BY X.InsDate
