Motivation

The data table has 20 fields, but I only want to query 19 of them. Sea-orm does not seem to support field exclusion at present. It is too troublesome to call .column() 19 times

Proposed Solutions

add select api

fn column_exclude<C>(mut self, col: C) -> Self
    where
        C: ColumnTrait,
    {
        // code...
        self
    }
