Change subject: IMPALA-941: Fix support for an identifier that starts with a number ...................................................................... IMPALA-941: Fix support for an identifier that starts with a number Impala has supported an identifier that starts with a number for quite some time. However, its implementation is broken, especially when it comes to using it in a fully-qualified name. This patch fixes the scanner to fix support for an idenfifier that starts with a number. For example: Before the fix: > select * from 123_bar; --> this is OK > select * from foo. 123_bar; --> this is OK > select * from foo .123_bar; --> this is not OK > select * from foo.123_bar; --> this is not OK After the fix: > select * from 123_bar; --> this is OK > select * from foo. 123_bar; --> this is OK > select * from foo .123_bar; --> this is OK > select * from foo.123_bar; --> this is OK Testing: - Added a new parser test - Ran all FE tests Change-Id: I8a715be73553247ce80a1ba841712191d64f9730 --- M fe/src/main/jflex/sql-scanner.flex M fe/src/test/java/org/apache/impala/analysis/ParserTest.java 2 files changed, 40 insertions(+), 1 deletion(-) git pull ssh://gerrit.cloudera.org:29418/Impala-ASF refs/changes/27/11927/2 -- To view, visit http://gerrit.cloudera.org:8080/11927 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-Project: Impala-ASF Gerrit-Branch: master Gerrit-MessageType: newchange Gerrit-Change-Id: I8a715be73553247ce80a1ba841712191d64f9730 Gerrit-Change-Number: 11927 Gerrit-PatchSet: 2 Gerrit-Owner: Fredy Wijaya <fwij...@cloudera.com>
