如何在另一栏中为每个不同价值提取总额?
原标题:How get the sum for every distinct value in another column?

附录一

ID    price    
-------------
 1     10      
 1     10      
 2     20      
 2     20      
 3     30
 3     30

每一次休息时间。 我想获得价格价值的总和,但只有一次获得国际发展法中每个不同价值。

因此,鉴于上述例子,我会得出以下一些看法:

ID    price    
-------------
 1     20          
 2     40           
 3     60

此外,我可能会对一个职位进行同样的调查。 问题是,其他员额使用Oracle,而我则使用MySQL。

最佳回答

页: 1

SELECT ID, 
       SUM(price) AS price
FROM YourTable
GROUP BY ID
问题回答

在我审查你的问题时,我以简单的答复总结如下:

SELECT DISTINCT(ID), SUM(PRICE) 
FROM TABLE_NAME
GROUP BY ID;
