MySQL附加所有列值

Question

我有一个名为material_line_item的表格，在该表格中有3列1.item_master_id 2.received_quantity和3.ordered_quantity我想要一个查询来计算这两个字段中的所有数量（received_quantity` and `ordered_quantity）基于item_master_id。

Answer 1

这应该有所帮助：

SELECT item_master_id, sum(received_quantity), sum(ordered_quantity) FROM material_line_item
GROUP BY item_master_id

Answer 2

与上述解决方案相同，但已格式化：）

  

SELECT item_master_id ,Sum(received_quantity) Total_Received_Qty ,Sum(ordered_quantity) Total_Ordered_Qty FROM material_line_item GROUP BY item_master_id
