SQL Access帮助总结来自2个不同的表

Question

我有这些表

table 1

id      price
1       30
2       40
3       50


table 2

    id      price
    1       70
    2       5
    3       10

我想要一个基于price汇总ID值的查询 比如table1.id = table2.id然后总和table1.price和table2.price 最终结果应该是这样的

table 3

    id      price
    1       100
    2       45
    3       60

Answer 1

你可以;

SELECT 
  TABLE1.ID, 
  TABLE1.PRICE+TABLE2.PRICE
FROM TABLE1 
  INNER JOIN TABLE2 ON TABLE1.ID = TABLE2.ID;

或者如果两个表中都有重复的ID;

SELECT 
  TABLE1.ID, 
  SUM(TABLE1.PRICE+TABLE2.PRICE)
FROM TABLE1 
  INNER JOIN TABLE2 ON TABLE1.ID = TABLE2.ID
  GROUP BY TABLE1.ID;
