## Proposed changes Problem: When inferring predicate，we lost cast of source expressions. Example: a = b and cast(a as targetType) = constant (cast(a as targetType) = constant ) this expression is define as source expression. we expect getting cast(b as targetType) = constant instead of b = constant Reason: When inferring predicate, we will compare original type of a and b. if they can be cast without precision lost, a new predicate would be created. But created predicate forgot to cast to target type Solved: Add cast to target type ## Further comments If this is a relatively large or complex change, kick off the discussion at [[email protected]](mailto:[email protected]) by explaining why you chose the solution you did and what alternatives you considered, etc... -- This is an automated message from the Apache Git Service.
