[jira] [Created] (KYLIN-1122) Kylin support detail data query from
fact table
Xiaoyu Wang created KYLIN-1122:
----------------------------------
Summary: Kylin support detail data query from fact table
Key: KYLIN-1122
URL: https://issues.apache.org/jira/browse/KYLIN-1122
Project: Kylin
Issue Type: New Feature
Components: Query Engine
Affects Versions: v1.2
Reporter: Xiaoyu Wang
Assignee: liyang
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.
