Problem:
========
c1+1 and c2 are both with LONGLONG type, but floor(c1+1) and floor(c2) have different types.
How to repeat:
> With --column-type-info
drop table if exists t1;
create table t1(c1 int, c2 bigint);
select c1+1, floor(c1+1), c2, floor(c2) from t1;
Suggested fix:
floor(c1+1) and floor(c2) have the same type.
