> This is a problem that I can not get column data here. > > From example: when `select * from (values (1)) where column1 = 0`, I can not know the column name is column1 here. Perhaps we can retrieve the column names from the schema of the physical plan. https://github.com/apache/arrow-datafusion/blob/31b9b48b08592b7d293f46e75707aad7dadd7cbc/datafusion-cli/src/exec.rs#L240 And then pass the schema to `print_batches`, using it when batches are empty. ```rust let schema = physical_plan.schema(); print_options.print_batches(&results, &schema, now)?; ``` -- This is an automated message from the Apache Git Service.
