php - 从 mysql 数据库中的每个值获取最后的结果

Question

我有一个数组，其中包含马匹列表。

我希望能够遍历该数组并拉出每匹马的最后结果。

目前我的代码如下所示:

select count(*),Horse,Place from horsesrp where Horse In (".$horsearray.")")

我如何修改它，以便只显示数组中的马的最后结果。

下面是我的数组的输出

数据库保存赛马结果，因此我想获取每匹马的最后结果

运行以下 sql 命令将产生以下结果: “从 horsesrp 中选择地点，马匹，其中马匹位于 (".$horsearray.")”

Haines Rich Again Uganda Glory Rich Again Sarlat Rich Again Gracious George Lady Brigid Rich Again Smokethatthunders Dialogue L'Inganno Felice Pearl Noir

因为 cna be saw rich Again 显示了几次，我只想得到最后的结果(仅 1 个结果)

我已经尝试过"select Place, Horse from horsesrp where Horse In (".$horsearray.") limit 1"但这只是返回第一匹马海恩斯

Answer 1

我想我明白你想做什么......

选择 (从 horserp 中选择地点作为 rp，其中 rp.Horse = Horse Order By id DESC LIMIT 1)作为 地点， 马 从 马srp 马在 (".$horsearray.")")

我希望 id 是您的主键并且是一个整数。也应该适用于日期时间或日期列。
