如何獲得當年和前一年的單一查詢的盧比總和？

Question

我想選擇當年盧比和上年盧比的材料明智的總和。以下是我的表中的字段：

|Material_Number|Material_name|Date  |Rupees | 
    |1    |abc   |2014-02-01|1.20,000 | 
    |1    |abc   |2014-02-02|50,000 | 
    |1    |abc   |2013-05-05|1,50,000 | 
    |5    |pqr   |2012-01-05|20,000 | 
    |2    |xyz   |2013-05-04|10,000 | 
    |2    |xyz   |2014-01-04|10,100 | 
    ---------------------------------------------------- 

我想顯示當年和前一年的盧比的材料明智的總和。以下是我希望我的表結構：

--------------------------------------------------- 
    |Previous_Year_sum| Material_name|Current Year_sum| 
    --------------------------------------------------- 
    |1,20,000   | abc   | 1,50,000  | 
    --------------------------------------------------- 

Answer 1

試試這個使用SUM()與CASE condtions

SELECT 
SUM(CASE WHEN YEAR(`Date`) = YEAR(NOW()) -1 THEN 
    REPLACE (Rupees, ',', '') 
    ELSE 0 END) 
Previous_Year_sum, 
Material_name, 
SUM(CASE WHEN YEAR(`Date`) = YEAR(NOW()) THEN 
REPLACE (Rupees, ',', '') 
    ELSE 0 END)current_year 
FROM `Table1` 
GROUP BY Material_name

Answer 2

select YEAR(Date) as year , SUM(rupees), material_name from test group by material_name, year;
