我有这个查询
SELECT concat(order_delivery_data.order_delivery_data_name,' sent'),
sum(case `order`.order_status when 'sent' then 1 else 0 end) '0-7 days'
FROM order_delivery_data
INNER JOIN `order` ON order_delivery_data.order_id = `order`.order_id
where order_delivery_data.order_delivery_data_name in ('Казахстан КАЗПОЧТА')
and order_statusUpdatedAt >= DATE_SUB(CURRENT_DATE, INTERVAL 7 DAY)
UNION
SELECT concat(order_delivery_data.order_delivery_data_name,' parcelonaplace'),
sum(case `order`.order_status when 'parcel-on-a-place' then 1 else 0 end) parcelonaplace
FROM order_delivery_data
INNER JOIN `order` ON order_delivery_data.order_id = `order`.order_id
where order_delivery_data.order_delivery_data_name in ('Казахстан КАЗПОЧТА')
and order_statusUpdatedAt >= DATE_SUB(CURRENT_DATE, INTERVAL 7 DAY)
显示2列。 如何在同一个查询中再添加一列?
答案 0 :(得分:1)
在case语句中使用条件聚合并更改where子句。 根据所需的结果,您可能需要更改第二个总和以使用日期范围而不仅仅是>间隔14天。
SELECT concat(order_delivery_data.order_delivery_data_name,' sent'),
sum(case When `order`.order_status = 'sent'
AND order_statusUpdatedAt >= DATE_SUB(CURRENT_DATE, INTERVAL 7 DAY) then 1 else 0 end) '0-7 days',
sum(case When `order`.order_status = 'sent'
AND order_statusUpdatedAt >= DATE_SUB(CURRENT_DATE, INTERVAL 14 DAY) then 1 else 0 end) '8-14 days'
FROM order_delivery_data
INNER JOIN `order` ON order_delivery_data.order_id = `order`.order_id
WHERE order_delivery_data.order_delivery_data_name in ('Казахстан КАЗПОЧТА')
AND order_statusUpdatedAt >= DATE_SUB(CURRENT_DATE, INTERVAL 14 DAY)
UNION
SELECT concat(order_delivery_data.order_delivery_data_name,' parcelonaplace'),
sum(case when `order`.order_status = 'parcel-on-a-place'
AND order_statusUpdatedAt >= DATE_SUB(CURRENT_DATE, INTERVAL 7 DAY) then 1 else 0 end) `parcelonaplace 0-7`,
sum(case when `order`.order_status = 'parcel-on-a-place'
AND order_statusUpdatedAt >= DATE_SUB(CURRENT_DATE, INTERVAL 14 DAY) then 1 else 0 end) `parcelonaplace 8-14
FROM order_delivery_data
INNER JOIN `order` ON order_delivery_data.order_id = `order`.order_id
WHERE order_delivery_data.order_delivery_data_name in ('Казахстан КАЗПОЧТА')
AND order_statusUpdatedAt >= DATE_SUB(CURRENT_DATE, INTERVAL 14 DAY)
