Xiaoyu Wang commented on KYLIN-1122:
------------------------------------
When I add the integration test case for RAW query.
I see the InvertedIndex test case in kylin-it/src/test/resources/query/sql_ii
folder.
The II case is support to query RAW data!
This case is conflict with my RAW query case, because if one column defined RAW
function,when select the column with out group by and other metric, it will be
route to only query the base cuboid! so the II case will fail!
Any suggestions?

> Now Kylin does not support query correct detail rows from fact table like:
> select column1,column2,column3 from fact_table
> The jira KYLIN-1075 add the "SUM" function on the measure column if defined.
> But only the column number type is support.
> I change some code to support this issue:
> Add a "VALUE" measure function : the same value and datatype in the input and
> output of this function.
> If you want to query detail data from fact table
> *require*:
> 1.Configure the column which not dimensions to "VALUE" or "SUM" measure.(If
> not configure measure function in the column will get NULL value)
> 2.The source table must has an unique value column and configure it as
> dimension.
> If you have the better solution please comment here.
