如何合並兩個 sql 查詢結果？ 一個查詢包含 GROUP BY

Question

我有一張如下表

id, date, type, quantity, vendor
'1','2020-04-05','2424A','200','vendor1'

'2','2020-04-05','2424','350','vendor1'

'3','2020-04-05','2424A1','150','vendor1'

'4','2020-04-05','2425','400','vendor1'

'5','2020-04-05','MA5878','200','vendor2'

我使用 Java 作為我的后端。 我已經嘗試過這些查詢

1. SELECT vendor, type, quantity FROM reports;

vendor, type, quantity
'vendor1', '2511', '200'

'vendor1', '5120', '350'

'vendor1', '2520', '150'

'vendor1', '5114', '400'

2. SELECT vendor, SUM(quantity) FROM reports where date = '2020-04-05' GROUP BY vendor;

vendor, SUM(quantity)
'vendor1', '1100'

'vendor2', '20600'

我需要結合以上 2 個查詢結果。 有人可以指導我進一步進行。

試試這個：

WITH a AS (
    SELECT vendor, ont_type, quantity 
    FROM cpe_portal.ontfereports
), b as (
    SELECT vendor, SUM(quantity) as quantityb 
    FROM cpe_portal.ontfereports 
    WHERE date = '2020-04-05' 
    GROUP BY vendor
)
SELECT a.vendor, a.ont_type, a.quantity, b.quantityb
FROM a join b ON a.vendor = b.vendor
