The IT tests run successful! Please [~liyang.g...@gmail.com] help to review! I'm working on the patch for 1.x. and create a branch base on 1.x-staging later! > 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 > Fix For: v2.1, v1.3 > > Attachments: > 0001-KYLIN-1122-Kylin-support-detail-data-query-from-fact(2.x-staging).patch, > 0001-KYLIN-1122-Kylin-support-detail-data-query-from-fact(update-v2-1.x-staging).patch, > > 0001-KYLIN-1122-Kylin-support-detail-data-query-from-fact-new-impl-under-refactoring-2.x-staging.patch > > > 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
