Change subject: IMPALA-9745: Propagate source type when doing constant propagation ...................................................................... IMPALA-9745: Propagate source type when doing constant propagation When doing constant propagation the source type was not being propagated to the target expression leading to an analysis failure. The behavior is most easily reproducible with STRING to TIMESTAMP conversion in the presence of other predicates. This patch fixes this by adding an implicit cast if needed for such cases. Testing: - Added planner test and ran other planner tests - Added end-to-end test Change-Id: Ic3853478945229440f733c256ea225639f9178ff --- M fe/src/main/java/org/apache/impala/analysis/ConstantPredicateHandler.java M testdata/workloads/functional-planner/queries/PlannerTest/constant-propagation.test M testdata/workloads/functional-query/queries/QueryTest/range-constant-propagation.test 3 files changed, 38 insertions(+), 3 deletions(-) git pull ssh://gerrit.cloudera.org:29418/Impala-ASF refs/changes/64/17064/1 -- To view, visit http://gerrit.cloudera.org:8080/17064 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-Project: Impala-ASF Gerrit-Branch: master Gerrit-MessageType: newchange Gerrit-Change-Id: Ic3853478945229440f733c256ea225639f9178ff Gerrit-Change-Number: 17064 Gerrit-PatchSet: 1 Gerrit-Owner: Aman Sinha <[email protected]>
