Question

我有一个连接表，在我想要与主表连接的表上有一个日期时间列名delivery_date_to，我想将delivery_date_to减去当前日期时间，减法结果将以天和小时格式（例如：2天23小时）作为记录。以下是我加入该表格的方式，

SELECT marketplace_orders.entity_id as id, 
       sales_order.delivery_date_to as delivery_date_to,
       (deliver_date_to - current_time = xx days xx hour) as time_left
FROM marketplace_orders 
INNER JOIN sales_order
      ON sales_order.entity_id = marketplace_orders.order_id
      AND sales_order.status IN ("pending","processing")

试试这个解决方案：

SELECT 
    marketplace_orders.entity_id as id, 
    sales_order.delivery_date_to as delivery_date_to,
    CONCAT(TIMESTAMPDIFF(Day,deliver_date_to,NOW()), ' days ',
    MOD(TIMESTAMPDIFF(HOUR,deliver_date_to,NOW()),24), ' hour')  as time_left
FROM marketplace_orders 
INNER JOIN sales_order
    ON sales_order.entity_id = marketplace_orders.order_id
       AND sales_order.status IN ("pending","processing")
