Subject [jira] [Created] (CALCITE-1754) queries grouping by timestampadd throws ClassCastException
Date Thu, 13 Apr 2017 12:04:41 GMT
hongbin ma created CALCITE-1754:
-----------------------------------

             Summary: queries grouping by timestampadd throws ClassCastException
                 Key: CALCITE-1754
                 URL: https://issues.apache.org/jira/browse/CALCITE-1754
             Project: Calcite
          Issue Type: Bug
    Affects Versions: 1.12.0
            Reporter: hongbin ma
            Assignee: Julian Hyde


using CSVTest:

{code}
    checkSql("model","select count(*),  JOINEDAT from EMPS group by JOINEDAT ");
{code}

works well, however 

{code}
    checkSql("model","select count(*), {fn timestampadd(SQL_TSI_DAY, 1, JOINEDAT) }  from
EMPS group by {fn timestampadd(SQL_TSI_DAY, 1, JOINEDAT ) } ");
{code}

throws 

{code}
Caused by: java.lang.ClassCastException: java.lang.Integer cannot be cast to java.sql.Date
