Question

我的查询如下：

SELECT MAX(x.id) as id,
x.name, x.timestamp, x.balance
FROM sheet x
JOIN
    (SELECT p.name,MAX(id) AS max_id, p.rate
    FROM sheet p GROUP BY p.name) y
ON y.max_id = x.id
GROUP BY x.name

以动态方式查询仅IN的名称的最佳做法是：

array= ['flake', 'shane', 'klar']

我用不同状态的join（）尝试了类似的事情：

WHERE x.name IN (' + array.join() + ')

尝试一下：

SELECT MAX(x.id) as id,x.name,x.timestamp,x.balance FROM sheet x JOIN (SELECT p.name,MAX(id) AS max_id,p.rate FROM sheet p GROUP BY p.name) y ON y.max_id = x.id WHERE x.name IN ('flake', 'shane', 'klar') GROUP BY x.name
