------------------------------

             Summary: Cannot group by the functions without ()
                 Key: DRILL-3798
                 URL: https://issues.apache.org/jira/browse/DRILL-3798
             Project: Apache Drill
          Issue Type: Bug
          Components: Functions - Drill
    Affects Versions: 1.1.0
            Reporter: Hao Zhu
            Assignee: Mehant Baid


Drill can not group-by the function without ().
eg:
{code}
SELECT CURRENT_DATE 
FROM hive.h1db.testdate
group  by CURRENT_DATE;


  Caused By (org.apache.calcite.sql.validate.SqlValidatorException) Column 'CURRENT_DATE' not found in any table
{code}

Bad ones:
{code}
SELECT CURRENT_TIME 
FROM hive.h1db.testdate
group  by CURRENT_TIME;

SELECT CURRENT_TIMESTAMP 
FROM hive.h1db.testdate
group  by CURRENT_TIMESTAMP;

SELECT LOCALTIME 
FROM hive.h1db.testdate
group  by LOCALTIME;

SELECT LOCALTIMESTAMP 
FROM hive.h1db.testdate
group  by LOCALTIMESTAMP;
{code}

Good ones:
{code}
SELECT NOW()
FROM hive.h1db.testdate
group  by NOW();

SELECT TIMEOFDAY()
FROM hive.h1db.testdate
group  by TIMEOFDAY();

SELECT UNIX_TIMESTAMP()
FROM hive.h1db.testdate
group  by UNIX_TIMESTAMP();

SELECT PI()
FROM hive.h1db.testdate
group  by  PI();
{code}
