我想做喜欢的，但对于另一个不起作用的情况。
这是我的示例表：

编辑
我试过这个问题：
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
从检验报告
按日期（检查日期时间）分组，模型
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
我想做一张桌子，像：
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
此查询几乎接近答案，但我无法计算接受和拒绝结果，然后在同一日期分组。请尝试我的查询。
最佳答案
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
