     * ### Examples
     *
     * ```ts
     * async function updatePerson(id: number, updates: UpdateablePerson, returnLastName: boolean) {
     *   return await db
     *     .updateTable('person')
     *     .set(updates)

     * ```
     *
     * Any selections added inside the `if` callback will be added as optional fields to the
     * output type since we can't know if the selections were actually made before running
     * the code. In the example above the return type of the `updatePerson` function is:
     *
