> I had another idea about how to preserve the improvements made to nullif but avoid this bug. Perhaps instead of simplifying to CASE entirely, we had the the physical function and instead called into the CaseExpr instead in the ExecutionPlan I tried that avenue as well. The problems is that with ScalarUDF at the moment you only get eager evaluation. There's no way to achieve the lazy evaluation `coalesce` requires. -- This is an automated message from the Apache Git Service.
