Vuk Ercegovac has uploaded a new patch set (#8). Change subject: IMPALA-1767 Adds predicate to test boolean values true, false, unknown. ......................................................................
IMPALA-1767 Adds predicate to test boolean values true, false, unknown. Adds a new expression to represent the following boolean predicate: <expr> IS [NOT] (TRUE | FALSE | UNKNOWN) The expression is rewritten into compound expressions using negation, is null, and equality. As a result, there are no BE operators to eval this predicate. Testing: - Frontend: parser, analyzer, rewriter, tosql - EndToEnd query expressions Change-Id: I5bd0aa82a0316ac236b7ecf8612ef4b30c016a00 --- M fe/src/main/cup/sql-parser.cup M fe/src/main/java/org/apache/impala/analysis/Analyzer.java A fe/src/main/java/org/apache/impala/analysis/BoolTestPredicate.java A fe/src/main/java/org/apache/impala/rewrite/BoolTestToCompoundRule.java M fe/src/test/java/org/apache/impala/analysis/AnalyzeExprsTest.java M fe/src/test/java/org/apache/impala/analysis/ExprRewriteRulesTest.java M fe/src/test/java/org/apache/impala/analysis/ParserTest.java M fe/src/test/java/org/apache/impala/analysis/ToSqlTest.java M testdata/workloads/functional-query/queries/QueryTest/exprs.test 9 files changed, 462 insertions(+), 20 deletions(-) git pull ssh://gerrit.cloudera.org:29418/Impala-ASF refs/changes/14/8014/8 -- To view, visit http://gerrit.cloudera.org:8080/8014 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-MessageType: newpatchset Gerrit-Change-Id: I5bd0aa82a0316ac236b7ecf8612ef4b30c016a00 Gerrit-PatchSet: 8 Gerrit-Project: Impala-ASF Gerrit-Branch: master Gerrit-Owner: Vuk Ercegovac <vercego...@cloudera.com> Gerrit-Reviewer: Alex Behm <alex.b...@cloudera.com> Gerrit-Reviewer: Dimitris Tsirogiannis <dtsirogian...@cloudera.com> Gerrit-Reviewer: Philip Zeyliger <phi...@cloudera.com> Gerrit-Reviewer: Thomas Tauber-Marshall <tmarsh...@cloudera.com> Gerrit-Reviewer: Vuk Ercegovac <vercego...@cloudera.com>
