Takeshi Yamamuro created SPARK-20964: ----------------------------------------
Summary: Make some keywords reserved along with the ANSI/SQL standard Key: SPARK-20964 URL: https://issues.apache.org/jira/browse/SPARK-20964 Project: Spark Issue Type: Improvement Components: SQL Affects Versions: 2.1.1 Reporter: Takeshi Yamamuro Priority: Minor The current Spark has many non-reserved words that are essentially reserved in the ANSI/SQL standard (http://developer.mimer.se/validator/sql-reserved-words.tml). https://github.com/apache/spark/blob/master/sql/catalyst/src/main/antlr4/org/apache/spark/sql/catalyst/parser/SqlBase.g4#L709 This is because there are many datasources (for instance twitter4j) that unfortunately use reserved keywords for column names (See [~hvanhovell]'s comments: https://github.com/apache/spark/pull/18079#discussion_r118842186). We might fix this issue in future major releases. -- This message was sent by Atlassian JIRA (v6.3.15#6346) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
