Xiaoxiang Yu reassigned KYLIN-5332: ----------------------------------- Assignee: sibing.zhang > After turning on the switch > "kylin.query.use-tableindex-answer-select-star.enabled", select * only > answers the dimension in the cube, but the table index contains more columns > ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- > > Key: KYLIN-5332 > URL: https://issues.apache.org/jira/browse/KYLIN-5332 > Project: Kylin > Issue Type: Bug > Affects Versions: 5.0-alpha > Reporter: sibing.zhang > Assignee: sibing.zhang > Priority: Major > Fix For: 5.0-alpha > > > 该现象表现为dimension中有5个列,但是tableindex中有10个列。通过select * > 查询出来的结果仅有5个列。预期是需要查询出全部的10个列。 > *RootCause:* > 开启开关 > “kylin.query.use-tableindex-answer-select-star.enabled”后,olaptable在注册sourceColumn的时候,会根据当前table在model中查询上线的模型。如果没有找到则返回所有列,如果找到,则返回model的effectDimensions作为表的暴露列。 > 当前逻辑中dimension和measure会被一起写入table index,但是measure写入table > index时并没有把该列设置为dimension,导致获取不到该列。查询select *的时候,则会缺少列。 > *Fix Design:* > 直接通过dataflow获取allColumn,这个column来源索引中的列。 -- This message was sent by Atlassian Jira (v8.20.10#820010)
