得到的所有结果与具有相同ID的第一项相同

Question

首先看这张照片。这是我想在网上展示的结果！ correct result

但是，我得到的结果与第一项相同 wrong one

例如，对于前5个结果，这是错误的。

Employee Id Crse Id Class Sec   Class Mtg Nbr   Strm    Descr

0010846 002668  01  1   2163    SOCIAL WELFARE POLICY

结果应为

0010054 006833  01  1   2163    POLYNESIAN DRUM ENSEMBLE

0010054 006833  01  2   2163    POLYNESIAN DRUM ENSEMBLE

0010846 006423  01  1   2163    SOCIAL RESEARCH METHODS

我不知道为什么计算机只获得每个emplid的第一个值而不是整个emplid的每个值。

这些是我的代码。请帮我查看哪里出错了。谢谢！
