Question

是否可以将带有CTE表达式的以下SQL查询转换为子查询版本？它适用于SQL 8，但我需要在SQL 5上运行

WITH no_duplicate AS
(   SELECT * , ROW_NUMBER() OVER (PARTITION BY lead_google_client_id ORDER BY lead_google_client_id DESC) AS single_googleClientID
FROM properties
)
SELECT lead_referral,
count(*) as total,
count(case when state = 'rejected' and priority != 3 then 1 end) as rejected
FROM no_duplicate
WHERE single_googleClientID=1
GROUP BY lead_referral

Answer 1

免责声明：我不确定您要完成什么。为此，您将必须提供更多信息，例如properties表中的示例数据。

尝试一下：

SELECT 
  ROW_NUMBER() OVER (PARTITION BY lead_google_client_id ORDER BY lead_google_client_id DESC) AS single_googleClientID, lead_referral,
  count(*) as total,
  count(case when state = 'rejected' and priority != 3 then 1 end) as rejected
FROM properties
WHERE single_googleClientID=1
GROUP BY lead_referral
