Xianqing He has uploaded a new patch set (#2). ( http://gerrit.cloudera.org:8080/16353 )
Change subject: IMPALA-10096: Use the original ordinal if the group by ordinal reference is a constant int ...................................................................... IMPALA-10096: Use the original ordinal if the group by ordinal reference is a constant int The SelectStmt's groupingExprs_ using the analyzed version and the ordinal reference will be substituted. It will throw exception if the ordinal reference is still a numeric literal, because we will re-analyze after sql rewritten. For example, here "count(1)" is rewritten to "count(*)" so we need to re-analyze the new query. select 13, id, count(1) from dimtbl group by 1, 2; The rewritten sql should be select 13, id, count(*) from dimtbl group by 1, id; If the original query uses "count(*)", it won't hit the bug since there are no rewriting happens. Testing: - Added new unit tests with ordinal in SELECT and GROUP BY - Ran 'mvn test' for the FE Change-Id: I34f659d15073d69aa0a4685f56ad94557df86560 --- M fe/src/main/java/org/apache/impala/analysis/SelectStmt.java M testdata/workloads/functional-planner/queries/PlannerTest/aggregation.test 2 files changed, 71 insertions(+), 1 deletion(-) git pull ssh://gerrit.cloudera.org:29418/Impala-ASF refs/changes/53/16353/2 -- To view, visit http://gerrit.cloudera.org:8080/16353 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-Project: Impala-ASF Gerrit-Branch: master Gerrit-MessageType: newpatchset Gerrit-Change-Id: I34f659d15073d69aa0a4685f56ad94557df86560 Gerrit-Change-Number: 16353 Gerrit-PatchSet: 2 Gerrit-Owner: Xianqing He <[email protected]> Gerrit-Reviewer: Aman Sinha <[email protected]> Gerrit-Reviewer: Impala Public Jenkins <[email protected]> Gerrit-Reviewer: Quanlong Huang <[email protected]>
