Change subject: IMPALA-6314: Add run time scalar subquery check for uncorrelated subqueries ...................................................................... Patch Set 9: (1 comment) http://gerrit.cloudera.org:8080/#/c/9005/9/fe/src/main/java/org/apache/impala/planner/SingleNodePlanner.java File fe/src/main/java/org/apache/impala/planner/SingleNodePlanner.java: http://gerrit.cloudera.org:8080/#/c/9005/9/fe/src/main/java/org/apache/impala/planner/SingleNodePlanner.java@1116 PS9, Line 1116: if (inlineViewRef.getViewStmt().isRuntimeScalar()) { > The optimization is definitely intentional and it's not clear to me why thi Looking at the example query again, I think it's ok that it succeeds. We're just deducing information from the query. I'm in favor of removing your quick fix to InlineViewRef.analyze() and accept that we can infer that the query is semantically correct as a whole. We should definitely add this case query as a test though and explain the behavior. -- To view, visit http://gerrit.cloudera.org:8080/9005 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-Project: Impala-ASF Gerrit-Branch: master Gerrit-MessageType: comment Gerrit-Change-Id: I0f52b93a60eeacedd242a2f17fa6b99c4fc38e06 Gerrit-Change-Number: 9005 Gerrit-PatchSet: 9 Gerrit-Owner: Zoltan Borok-Nagy <[email protected]> Gerrit-Reviewer: Alex Behm <[email protected]> Gerrit-Reviewer: Attila Jeges <[email protected]> Gerrit-Reviewer: Csaba Ringhofer <[email protected]> Gerrit-Reviewer: Dimitris Tsirogiannis <[email protected]> Gerrit-Reviewer: Tim Armstrong <[email protected]> Gerrit-Reviewer: Vuk Ercegovac <[email protected]> Gerrit-Reviewer: Zoltan Borok-Nagy <[email protected]> Gerrit-Comment-Date: Thu, 22 Feb 2018 08:05:29 +0000 Gerrit-HasComments: Yes
