I'm trying to make a small query to an Oracle using `createQueryBuilder` but it doesn't return records.

I have noticed that TypeORM generates SQL in lowercase and with quotes (like this: `SELECT "m"."codigo" AS "m_codigo", "m"."descripcion" AS "m_descripcion" FROM "moneda" "Moneda", "moneda" "m"`) and this is what is generating the problem in oracle because when I remove the quotes or ... I convert the query to uppercase, it returns data.

code:

```js
import { EntityRepository, getRepository, Repository , Entity, Column, PrimaryColumn} from "typeorm";

@Entity()
export class Moneda {

    @PrimaryColumn()
    codigo?:      number;

    @Column()
    descripcion?: string; 

    @Column()
    simbolo?:     string;

    @Column()
    decimales?:   number;   

}

@EntityRepository(Moneda)
export class MonedaRepository extends Repository<Moneda> {

    constructor() { super() }

    async getListaMonedas(){

        return await getRepository(Moneda).createQueryBuilder()
            .select( ["m.codigo", "m.descripcion"] )
            .from( Moneda, "m" )
            .getMany();
    }
}

//in another file...

    import { MonedaRepository } from "./store";
    const monedaRepository = new MonedaRepository();
    const monedas = await monedaRepository.getListaMonedas();
   console.log(monedas);

// result:   [ ]

```
