[jira] [Commented] (KYLIN-2538) extract(MONTH from CURRENT_DATE) cannot be selected as a column in sql
[ https://issues.apache.org/jira/browse/KYLIN-2538?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel=15980370#comment-15980370 ] Dong Li commented on KYLIN-2538: Yes it's on CI cubes. But actually CURRENT_DATE is a const value to return current date, for example, "select extract(MONTH from CURRENT_DATE)" will return right result, but will fail when other column/aggr func appears in the SQL. Thanks Roger. I will add more description in this JIRA to avoid misunderstanding. > extract(MONTH from CURRENT_DATE) cannot be selected as a column in sql > -- > > Key: KYLIN-2538 > URL: https://issues.apache.org/jira/browse/KYLIN-2538 > Project: Kylin > Issue Type: Bug > Components: Query Engine >Reporter: Dong Li >Assignee: liyang > > This SQL will fail with exceptions: > select extract(MONTH from CURRENT_DATE), count(*) from test_kylin_fact > Error message: > Error while executing SQL "select extract(MONTH from CURRENT_DATE), count(*) > from test_kylin_fact LIMIT 5": No TblColRef found in > EXTRACT_DATE(FLAG(MONTH), Reinterpret(CURRENT_DATE)) > Stacktrace: > Caused by: java.lang.IllegalStateException: No TblColRef found in > EXTRACT_DATE(FLAG(MONTH), Reinterpret(CURRENT_DATE)) > at > org.apache.kylin.query.relnode.OLAPProjectRel.buildColumnRowType(OLAPProjectRel.java:132) > at > org.apache.kylin.query.relnode.OLAPProjectRel.implementOLAP(OLAPProjectRel.java:117) > at > org.apache.kylin.query.relnode.OLAPRel$OLAPImplementor.visitChild(OLAPRel.java:83) > at > org.apache.kylin.query.relnode.OLAPLimitRel.implementOLAP(OLAPLimitRel.java:75) > at > org.apache.kylin.query.relnode.OLAPRel$OLAPImplementor.visitChild(OLAPRel.java:83) > at > org.apache.kylin.query.relnode.OLAPToEnumerableConverter.implement(OLAPToEnumerableConverter.java:85) > at > org.apache.calcite.adapter.enumerable.EnumerableRelImplementor.implementRoot(EnumerableRelImplementor.java:108) > at > org.apache.calcite.adapter.enumerable.EnumerableInterpretable.toBindable(EnumerableInterpretable.java:92) > at > org.apache.calcite.prepare.CalcitePrepareImpl$CalcitePreparingStmt.implement(CalcitePrepareImpl.java:1248) > at org.apache.calcite.prepare.Prepare.prepareSql(Prepare.java:306) > at org.apache.calcite.prepare.Prepare.prepareSql(Prepare.java:203) -- This message was sent by Atlassian JIRA (v6.3.15#6346)

[ https://issues.apache.org/jira/browse/KYLIN-2538?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel=15980337#comment-15980337 ] Roger Shi commented on KYLIN-2538: -- I suppose this query targets CI Data Model and Cube. If yes, CURRENT_DATE is not in the table. And count(*) should not in the query. The refined query is "select extract(MONTH from CAL_DT) from test_kylin_fact" and it returns the expected result.
