Subject [jira] [Created] (HIVE-11703) Make RegExp and RLike reserved keywords
Date Mon, 31 Aug 2015 22:18:46 GMT
Pengcheng Xiong created HIVE-11703:
--------------------------------------

             Summary: Make RegExp and RLike reserved keywords
                 Key: HIVE-11703
                 URL: https://issues.apache.org/jira/browse/HIVE-11703
             Project: Hive
          Issue Type: Sub-task
            Reporter: Pengcheng Xiong
            Assignee: Pengcheng Xiong


RegExp and RLike are treated as "precedenceEqualNegatableOperator" in Hive. They actually
come from MySQL. Both of them are not keywords in SQL2011. But they are reserved keywords
in MySQL. Making them reserved ones can eliminate the current 14 ambiguities that we have
in current Hive. If users still would like to use them as identifiers/function names, users
can "set hive.support.sql11.reserved.keywords=false;"
