> Key: PHOENIX-5388
> URL: https://issues.apache.org/jira/browse/PHOENIX-5388

> Issue Type: Bug
>Reporter: Ankit Singhal

>Priority: Major
> Fix For: 4.15.0, 5.1.0
>
> Attachments: PHOENIX-5388.patch, PHOENIX-5388_v2.patch

> Following query fails in the month of December:-
> {code}
> select NOW(), MONTH(NOW()) m,
> CASE
> WHEN MONTH(NOW()) = 12 THEN TO_TIME(YEAR(NOW()) || '-12-31 23:59:59.999')
> ELSE TO_TIME(YEAR(NOW()) || '-' || ( MONTH(NOW()) + 1 ) || '-01
> 23:59:59.999') - 1
> END AS this_month_end
> {code}
> It is due to an optimization we have during compilation where we evaluate the
> expression if they result in to constant so that we don't need to do it for
> every row.
> Currently parsing stack evaluates every expression if possible without
> considering any condition, resulting in evaluation of all three expression
> for CASE node, MONTH(NOW()) = 12 , TO_TIME(YEAR(NOW()) || '-12-31
> 23:59:59.999') ,TO_TIME(YEAR(NOW()) || '-' || ( MONTH(NOW()) + 1 ) || '-01
> 23:59:59.999') - 1) but evaluation of 3rd one will fail because of invalid
> month.
> Workaround: For the particular use-case , Following query though help in
> preventing the expressions of WHEN CASE to be evaluated to a constant at
> compile time.
