sql - full outer join matching on multiple criteria -


two tables trying join:

tablea: table contains of leads won bid , source , date. 

bid amount = tablea.price, source = tablea.lead_source_id, date = tablea.time

tableb: table contains of leads lost bid , source , date.

bid amount = tableb.cost, source = tableb.lead_source_id, date = tableb.bid_at

i able return number of bids won , lost bid , source , date. times there records in 1 table or other (we won bids or lost bids), appears outer join needed.

ideal output grouped lead_source_id, bid amount, , time such:

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

try following query.

;with tmp ( select lead_source_id,  [time] [date], price, count(*) won, 0 lost   tablea group lead_source_id, [time], price  union select lead_source_id, bid_at [date], cost price, 0 won, count(*) lost  tableb group lead_source_id, bid_at, cost)  select lead_source_id [lead source id], [date], price [bid amount], sum(won) won , sum(lost) lost tmp group lead_source_id, [date], price order lead_source_id, [date]

the common table expression (tmp) calculates number of won/lost bids , outer select groups data id, date , bid amounts.
