SQL Query a View
Select from it exactly like a real table — that's the entire point.
What & Why
Once created, a view is queried with ordinary SELECT statements — no special syntax, no awareness required that it's a view rather than a real table.

WITH active_campaign_summary AS (
SELECT
id AS campaign_id,
name,
channel,
spend,
start_date,
end_date
FROM marketing.campaigns
WHERE status = 'active'
)
SELECT campaign_id, name, channel, spend, start_date, end_date
FROM active_campaign_summary
ORDER BY campaign_id;RESULT — rows read from public.active_campaign_summary
| campaign_id | name | channel | spend | start_date | end_date |
|---|---|---|---|---|---|
| 1 | Spring Launch | google_ads | 55000.00 | 2024-01-15 | 2024-03-31 |
| 2 | Retention Webinar | 45000.00 | 2024-02-10 | 2024-04-15 | |
| 3 | Finance Retargeting | 50000.00 | 2024-03-12 | 2024-05-31 | |
| 4 | Enterprise Search | google_ads | 60000.00 | 2024-04-01 | 2024-06-30 |
The view query returns the same six-column active-campaign contract defined by the preceding CREATE VIEW lesson.
