#14 CASE in Statement throws exception

[Anonymous]

When parsing statements, which containe a CASE and the ELSE part of the CASE is a arithmetic function like /,+,- ... an exception is thrown.

Example statement throwing the exception:
select p, case when sum(a)=0 then 1 else 1*2 end as f from anything

the 1*2 part is the one causing the exception.

select p, case when sum(a)=0 then 1 else 2 end as f from anything
is parsed correctly

[RES]

The grammar just needs updated to accept a SimpleExpression for K_CASE statements instead of PrimaryExpession.
