I think you can do this today via [`SqlToRel::sql_to_expr`](https://docs.rs/datafusion/latest/datafusion/sql/planner/struct.SqlToRel.html#method.sql_to_expr) ## Step 1: Add an example to show how to use `SqlToRel::sql_to_expr` So add an example (perhaps `expr_to_sql.rs`) in https://github.com/apache/arrow-datafusion/tree/main/datafusion-examples/examples that showed how to call `SqlToRel` to parser the expression above ## Step 2: Add an API to DataFusion that made parsing SQL easier The idea is to avoid requiring PlannerContext, a `DFSchema`, etc). For example: ```rust let expr: Expr = parse_expr("c < 5")?; ``` Note this doesn't provide a schema. -- This is an automated message from the Apache Git Service.
