Hank Miller created CALCITE-3717:
------------------------------------
Summary: Query fails with "division by zero" exception
Key: CALCITE-3717
URL: https://issues.apache.org/jira/browse/CALCITE-3717
Project: Calcite
Issue Type: Bug
Reporter: Hank Miller
Hi, community. We use Calcite-1.21 to connect and compute data resident in
PostgreSQL and MySQL. It works pretty well. But we encountered a problem
yesterday.
We combine data from different datasources.
Assume the combined table is _T(...., c1, c2, c3)_, in which _c1, c2, c3_ are
integer columns. Then according to our business logic, we need to make further
data processing in Calcite.
{code:java}
select case when c1=0 then ..
when c2=0 then 1.0/c1 + ...
when c3=0 then 1.0/c1 + 1.0/c2 + ...
else -99.99 end
from T{code}
However, the query throws "java.lang.ArithmeticException: Division by zero".
Anything goes wrong?
