Php 何时将csv文件导入数据库行被洗牌？

当我将csv文件导入数据库时，行被洗牌。请参考图片

我需要导入而不洗牌行。我正在寻找一个多星期的解决办法。我无法解决这个问题

你能帮助任何人解决这个问题吗

两条注释：首先，数据库表的记录没有内部顺序。唯一存在的顺序是您在执行

按排序时强加的顺序。其次，您可能应该将问题编号拆分为自己的列，以便在查询时可以轻松地对记录进行排序。我将问题和问题编号串联起来，仅用于理解目的。那么只有我们才能追踪它是否被洗牌了。@Tim BiegeleisenYou没有抓住重点；这些记录总是在数据库中被“洗牌”。只有当您使用

Order BY

查询并提供该订单时，订单才存在。请遵循Tims注释-如果您的表中

Order BY ID

，您将看到它们“顺序正确”。查看您的图像，对照您所谈论的字段检查ID！非常感谢你的建议！！它现在工作得很好@TimBiegeleisen，
