Sql 在Oracle中按名称添加新列SUM Money

员工表：

Name | Can_use | Money    
Jack | Yes     | 1000    
Lara | Yes     | 1500    
Jack | No      | 500    
Jack | Yes     | 700    
Lara | Yes     | 500

我想创建一个视图表，结果如下：

Name | Can_use | Money | Sum    
Jack | Yes     | 1000  | 1700    
Lara | Yes     | 1500  | 2000    
Jack | No      | 500   | 1700    
Jack | Yes     | 700   | 1700    
Lara | Yes     | 500   | 2000

对于Employy，可以使用=是，然后总和+=金钱

救救我

求和窗口函数和CASE将解决您的问题

CREATE OR REPLACE VIEW yourView AS
SELECT Name,
       Can_use,
       Money,
       SUM(CASE WHEN Can_use = 'Yes' THEN Money ELSE 0 END) OVER (PARTITION BY Name) "Sum"
FROM yourTable;

       Can_use,
       Money,
       SUM(CASE WHEN Can_use = 'Yes' THEN Money ELSE 0 END) OVER (PARTITION BY Name) "Sum"
FROM yourTable;
