我尝试设置输入路径的Path环境变量：＆＃34; C：\ Program Files \ Java \ jdk1.8.0_101 \ db \ lib＆＃34; （.jar文件路径）但没有... 我通过输入相同的路径创建了一个名为CLASSPATH的新变量，但仍然没有... 如何将此路径链接到编译器？

You can't set CLASSPATH to the directory where the jar files are stored; you have to specify the actual jar file by its full name.
This is a difference between a directory full of java .class files, versus a directory full of java .jar files.
So set your CLASSPATH to:
c:\Program Files\Java\jdk1.8.0_101\db\lib\derby.jar;c:\Program Files\Java\jdk1.8.0_101\db\lib\derbyclient.jar
In your particular case, since the only class you're trying to reference is ClientDriver, which is in derbyclient.jar, you could just set CLASSPATH to c:\Program Files\Java\jdk1.8.0_101\db\lib\derbyclient.jar and leave derby.jar out, but at some point in the future you might want to reference other Derby classes, such as EmbeddedDriver, so you might as well put both derby.jar and derbyclient.jar into your CLASSPATH now.
