Question

我想查询：

Select cars.* from cars where cars.code in
(
select carCode from articles where 
numberofrecords with this car (it is not a column) >1
and Accepted=1
order by date
)

怎么写呢？

Answer 1

尝试这样的事情：

SELECT  cars.*
FROM    cars
WHERE   cars.code IN (
    SELECT  carCode
    FROM    articles
    WHERE   Accepted = 1
    GROUP BY carCode
    HAVING COUNT(articleId) > 1
)

Answer 2

这应该这样做：

SELECT c.*
FROM cars c
    JOIN
    (
        SELECT carCode 
        FROM articles
        WHERE Accepted = 1
        GROUP BY carCode
        HAVING COUNT(carCode) > 1
    ) a ON c.code = a.carCode
