How about this for a (very hacky) solution until we sort out the real one: 1. Add a new field to [`Case`](https://github.com/apache/datafusion/blob/e4f6a144ac652f3eac4fe3dfebe3649c32fb19de/datafusion/expr/src/expr.rs#L672-L671) to pass along the "we know it is nullable" flag: ```rust pub struct Case { pub expr: Option<Box<Expr>>, pub when_then_expr: Vec<(Box<Expr>, Box<Expr>)>, pub else_expr: Option<Box<Expr>>, /// ** NEW FIELD ** /// If this expression is known to be non-nullable (e.g. it came from /// simplifying a `IFNULL` expression) pub known_non_nullable: bool, } ``` -- This is an automated message from the Apache Git Service.
