like sum,max,top as example??the return type is decimal(19,2) ?? SHOW AS 
dimension??; 
after build cube success;

HI:
Because kylin only stores the aggregated data, not the detailed information of 
the data source.If ??entrust_balance?? be added to model as a dimension, you 
can query detail like select entrust_balance from table xx &nbsp;and get 
correct result.If you want to query SQL like ??Select * from table?? , you can 
config pushdown:http://kylin.apache.org/cn/docs/tutorial/query_pushdown.html
