MySQL 排序依据不一致

Question

我在 sql 中有一段代码，试图按 trades.id 字段的数字顺序获取投资组合、某些交易的股价。

问题是下面代码中的两个值都必须按数字顺序返回，以便根据权重计算某种类型的分配。

但是，

投资组合相对于trades.id字段的返回顺序如下

0,1,2,3,4,5,6...

从“股”派生的“权重”的返回顺序如下

1,2,3,4,5,6....0

它们的顺序都应该是0,1,2,3,4,5,6

PS。不是我的代码，但我必须修复它才能使应用程序正常工作

GROUP BY Ticker , Direction , Price , Commission
ORDER BY trades.id

Answer 1

我刚刚修复了该错误。包装股票的group_concat方法中的代码缺少order by trades.id。

(trades.Shares/ 
       (SELECT SUM(Shares) 
             FROM db.Trades WHERE id IN 
 ('102370''102371','102372','102373','102374','102375','102376','102377','102380','102400')),12) 
 order by trades.id) AS Weights   -- <- here
