Zoltan Haindrich created CALCITE-2731:
-----------------------------------------
Summary: Case statements are simplified with unsafe conditions
Key: CALCITE-2731
URL: https://issues.apache.org/jira/browse/CALCITE-2731
Project: Calcite
Issue Type: Bug
Reporter: Zoltan Haindrich
Assignee: Zoltan Haindrich
In CALCITE-1413 we were cautious to not simplify
{code}
CASE a=0 THEN 0 ELSE 1/a END
{code}
and it seemed good; however: {{RexProgramBuilder}} is also invokes simplify -
but the protection at that point is not able to work, because it sees only
references:
{code}
CASE $1 THEN $2 ELSE $3 END
{code}
