我正在尝试使用Spring Data Cassandra

我在使用Spring Data Cassandra时收到了堆栈跟踪中显示的以下错误.你能帮忙解决这个错误

我的pom.xml就是这样..

堆栈跟踪:

我的桌子是这样的

ID  VALUE  
1   4  
2   6  
3   12  

我想在mysql中以这种格式获得输出,你能为我提供相应的sql吗？

ID   VALUE  MAX_VALUE DIV_BY_MAX_VALUE  
1       4     12         0.33  
2       6     12         0.5   
3      12     12         1.0
