合併相似的行並相加它們的值？

Question

這是我的表：

URL   | Art | Design 
example1.com  1    
example1.com  1    
example1.com  1    
example1.com   1   
example2.com   1 
example2.com   1 

我要合併使用同一網址列，總結的過程中藝術與設計的價值，要達到這樣的：

URL   | Art | Design 
example1.com  3  1 
example2.com   2 

這是怎麼做起來難？

Answer 1

使用GROUP BY和SUM：

SELECT URL, SUM(Art) as Art, SUM(Design) AS Design 
FROM yourtable 
GROUP BY URL 

Answer 2

select URL,sum(art),sum(design) From MYTABLE group by URl 

Answer 3

試試這個：

SELECT URL, COUNT(Art), COUNT(Design) 
FROM myTable 
GROUP BY URL 

Answer 4

select url,SUM(art),SUM(design) from tab1 group by url 

哪裏TAB1是你的表名

Answer 5

您是否嘗試過任何東西到現在？

這是非常簡單：

select url, SUM(art) as Art, SUM(design) as Design from [MyTable] group by url
