Change subject: IMPALA-7905: Hive keywords not quoted for identifiers ...................................................................... Patch Set 7: (2 comments) Addressed recent review comments. http://gerrit.cloudera.org:8080/#/c/12009/5/fe/src/main/java/org/apache/impala/analysis/ToSqlUtils.java File fe/src/main/java/org/apache/impala/analysis/ToSqlUtils.java: http://gerrit.cloudera.org:8080/#/c/12009/5/fe/src/main/java/org/apache/impala/analysis/ToSqlUtils.java@116 PS5, Line 116: an identifier > I meant to refer to the method argument @ident here. But it is fine. Not to Took a second look. The text was ambiguous, using "identifier" for two distinct concepts. Reworded to be clearer. http://gerrit.cloudera.org:8080/#/c/12009/5/fe/src/main/java/org/apache/impala/analysis/ToSqlUtils.java@148 PS5, Line 148: / : public static boolean impalaNeedsQuotes(String ident) { : return SqlScanner.isReserved(ident) || : // Impala's scanner recognizes the ".123" portion of "db.123e45" as a decimal, : // so while the quoting is not necessary > ya, 123e45 is a valid decimal literal but not .123 part like you mentioned Reworded the comment and inserted an actual example that illustrates the issue. "3a3" is a fine unquoted identifier. "3e3" must be quoted, else it is a double. So, to be safe, we quote all identifiers that start with a digit. -- To view, visit http://gerrit.cloudera.org:8080/12009 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-Project: Impala-ASF Gerrit-Branch: master Gerrit-MessageType: comment Gerrit-Change-Id: I06cc20b052a3a66535a171c36b4b31477c0ba6d0 Gerrit-Change-Number: 12009 Gerrit-PatchSet: 7 Gerrit-Owner: Paul Rogers <prog...@cloudera.com> Gerrit-Reviewer: Bharath Vissapragada <bhara...@cloudera.com> Gerrit-Reviewer: Fredy Wijaya <fwij...@cloudera.com> Gerrit-Reviewer: Impala Public Jenkins <impala-public-jenk...@cloudera.com> Gerrit-Reviewer: Paul Rogers <prog...@cloudera.com> Gerrit-Comment-Date: Tue, 08 Jan 2019 00:37:35 +0000 Gerrit-HasComments: Yes
