操作数应包含1列 - MySQL不在
SELECT * from campaigns WHERE id not in(SELECT e.id_campaign, d.name, d.frequency, d.country, d.referral, d.bid, d.status, COUNT(e.id) AS countcap FROM campaigns d LEFT JOIN served e ON d.id = e.id_campaign WHERE d.status = 'Active' GROUP BY e.id_campaign HAVING countcap < d.frequency)
我得到错误“操作数应该包含1列” - 但我需要COUNT(e.id)
侃侃无极
