I'm not sure if this is the right issue, but we would also like to use named placeholders in `SELECT`. There's a fixme for this in the source: https://github.com/apache/datafusion/blob/500744d5c25499055e3b2ca46b022bc425989203/datafusion/sql/src/expr/value.rs#L141-L143 Our ideal workflow would be something like: - Use `PlannerContext::new().with_prepare_param_data_types(ts)` to pass (named!) parameter types into `SqlToRel` - Much later, bind values to the plan using `with_param_values(ParamValues::Map(...)` That doesn't work, because the planner always uses positional placeholders. That means we have to use `ParamValues::List` and get the order exactly right, which is brittle. -- This is an automated message from the Apache Git Service.
