[jira] [Closed] (CALCITE-817) Extension column cannot have name "row"

["Julian Hyde (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/CALCITE-817?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Julian Hyde closed CALCITE-817.
-------------------------------
    Resolution: Invalid

ROW (and ROWS) is a reserved key-word from SQL:99 onward. Example: {code}SELECT *
FROM emp
ORDER BY empno OFFSET 1 ROW FETCH NEXT 5 ROWS{code}

You can use a reserved keyword as an identifier, but you must quote it (using double quotes in the default lexical scheme): {code}SELECT deptno AS "ROW" FROM emp{code}
