Sql 为什么我的查询显示重复数据？

我怎样才能在我的提问中阻止这种重复

我有两张表格

个人信息 训练 现在一个人只有一个个人记录，但培训课程可以超过一个记录

但问题是，在培训课程中，个人信息记录也会重复，这是我不想重复的

如果此人接受过1次以上的培训，在不复制人员数据的情况下，您希望获得什么样的输出？请尝试添加差异。此处不清楚您希望获得什么样的输出，请提供更多详细信息。使用2个查询获取个人信息和培训/课程separately@Juventustech，你显然加入了他们，那么，您如何期望PersonalInfo不会重复？对于每个培训记录，您显然会得到填充有重复数据的PersonalInfo列。。。你认为一个人的几次训练在你的成绩中会是什么样子。。。您希望在PersonalInfo中看到什么？
