Pytanie: Jak należy dostosować to zapytanie, aby uzyskać wskaźniki kosztów i odsłon według źródła realizacji (supply_source)? SELECT device_type, operating_system, SUM(total_cost)/100000 AS total_cost_dollars, ((SUM(total_cost)/100000)/SUM(impressions))*1000 AS avg_cpm, SUM(impressions) AS impressions FROM dsp_impressions GROUP BY 1,2
- SELECT supply_source, SUM(total_cost)/100000000 AS total_cost_dollars, ((SUM(total_cost)/100000000)/SUM(impressions))*1000 AS avg_cpm, SUM(impressions) AS impressions FROM dsp_inventory GROUP BY 1
