Subject [jira] [Commented] (DRILL-2313) Query fails when one of the operands is a DATE literal without an explicit cast
Date Thu, 05 Mar 2015 21:43:38 GMT

    [ https://issues.apache.org/jira/browse/DRILL-2313?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14349500#comment-14349500
] 

Sean Hsuan-Yi Chu commented on DRILL-2313:
------------------------------------------

`A between B and C` will be translated to B <= A and A<= C later on.

So we have pattern like this `A < B` with different types (not-Any type) will fail in the
same manner.

Actually, constants (numbers & literals) causing pains sometimes. I am thinking if we
can just treat numbers & literals as ANY types, and let execution logic deal with type
things.

> For operations involving the date datatype, when one of the operands is a DATE literal
without a cast, query fails. 
> *The following query fails to validate:*
> {code:sql}
> SELECT
>          *
> FROM     
>          date_dim
>          
> WHERE    d_date BETWEEN '2002-3-01' AND cast('2002-3-01' AS DATE) 
> LIMIT 1;
> {code}
> Query failed: SqlValidatorException: Cannot apply 'BETWEEN' to arguments of type '<ANY>
BETWEEN <CHAR(9)> AND <DATE>'. Supported form(s): '<COMPARABLE_TYPE> BETWEEN
<COMPARABLE_TYPE> AND <COMPARABLE_TYPE>'
> *The following query executes fine:*
> {code:sql}
> SELECT
>          *
> FROM     
>          date_dim
>          
> WHERE    d_date BETWEEN '2002-3-01' AND 
>                   '2002-3-01'
> LIMIT 1;
> {code}
> Both the queries execute fine on postgres
