Question

我想加入两个表：

tableA ：此表包含我们通过BID，SOURCE和DATE赢得的所有潜在客户。

Bid Amount = tableA.price, Source = tableA.lead_source_id, Date = tableA.time

tableB ：此表包含我们因BID，SOURCE和DATE而丢失的所有潜在客户。

Bid Amount = tableB.cost, Source = tableB.lead_source_id, Date = tableB.bid_at

我希望能够通过BID，SOURCE和DATE返回我们WON和LOST的出价数量。通常情况下，只有一个表或另一个表中的记录（我们赢得所有出价或丢失所有出价），因此看起来需要外部联接。

理想输出将按照lead_source_id，出价金额和时间进行分组：

Lead Source ID, Date, Bid Amount, Won, Lost

1, 1/1/2015, $20, 5, 0 

1, 1/1/2015, $25, 0, 9

5, 1/1/2015, $30, 1, 1

10, 1/2/2015, $50, 0, 1

10, 1/2/2015, $55, 1, 0

Answer 1

尝试以下查询。

;WITH tmp AS (
SELECT lead_source_id,  [time] AS [Date], price, COUNT(*) AS won, 0 AS lost 
FROM  tableA
GROUP BY lead_source_id, [time], price 
UNION ALL
SELECT lead_source_id, bid_at AS [Date], cost AS price, 0 AS won, COUNT(*) AS lost 
FROM tableB
GROUP BY lead_source_id, bid_at, cost)

SELECT lead_source_id AS [Lead Source ID], [Date], price AS [Bid Amount], SUM(won) AS Won , SUM(lost) AS Lost
FROM tmp
GROUP BY lead_source_id, [Date], price
ORDER BY lead_source_id, [Date]

公用表格式（tmp）计算赢/出的出价数量，外部选择按ID，日期和出价金额对您的数据进行分组。
