Я получаю «Код ошибки: 1054. Неизвестный столбец E1.extensao в списке полей» Я изменил имена таблиц, но мой запрос выглядит следующим образом:
SELECT E1.stateName, E1.city, E1.boughtEnough, E2.bought
FROM
(SELECT count(DISTINCT idClient),city,stateName FROM
(SELECT
max(n.ordervalue) as boughtEnough,
m.idClient,
i.nome AS city,
i.id AS cityId,
i.stateName
FROM Clients c
INNER JOIN client_order m ON c.idClient = m.idClient
INNER JOIN orders n ON m.client_order = n.client_order
INNER JOIN orderDetail p ON n.idorder = p.idorder
AND p.idCurso = m.idCurso
INNER JOIN cities i ON c.city = i.id
WHERE
m.idCurso = '10'
GROUP BY
m.idClient,
i.nome,
i.id,
i.stateName
HAVING max(n.orders) >= 6) t
GROUP BY t.city, t.stateName
ORDER BY t.stateName,t.city) E1
JOIN (SELECT count(DISTINCT idClient),city,stateName FROM
(SELECT
count(n.ordervalue) as bought,
m.idClient,
i.nome AS city,
i.id AS cityId,
i.stateName
FROM Clients c
INNER JOIN client_order m ON c.idClient = m.idClient
INNER JOIN orders n ON m.client_order = n.client_order
INNER JOIN orderDetail p ON n.idorder = p.idorder
AND p.idCurso = m.idCurso
INNER JOIN cities i ON c.city = i.id
WHERE
m.idCurso = '10'
GROUP BY
m.idClient,
i.nome,
i.id,
i.stateName
HAVING ((max(n.orders) < 6) AND (count(n.orders) >= 1))) t
GROUP BY t.city, t.stateName
ORDER BY t.stateName,t.city) E2 ON E1.cityId = E2.cityId
Я больше привык к SQL Server, а не к MySQL. Что я не так делаю?
