検索ログ - 指定した期間の完全なリストを取得する方法

[JammyDodger]

こんな感じの方が良いかと思います。

-- [params]
-- date :start_date
-- date :end_date


WITH results AS (


SELECT LOWER(term) AS term,
       COUNT(*) AS searches,
       SUM(CASE WHEN search_result_id IS NOT NULL THEN 1 ELSE 0 END) AS click_through
FROM search_logs
WHERE created_at BETWEEN :start_date AND :end_date
GROUP BY term

)


SELECT term AS "検索語",
       searches AS "検索数",
       click_through AS "クリック数",
       CEIL ((click_through/searches::float) * 100) || '%' AS "CTR"
FROM results
ORDER BY searches DESC

これで役立つことを願っていますが、調整が必要な場合はお知らせください。
