joins overwrite select?

export const pets = sqliteTable('pets', {
    id: text({ length:12 }).primaryKey().$default(() => nanoid()),
    owner_id: text().notNull().references(() => owners.id, { onDelete: 'cascade' }),
    name: text().notNull(),
})

export const owners = sqliteTable('owners', {
    id: text({ length:12 }).primaryKey().$default(() => nanoid()),
    name: text().notNull(),
})

const pet_id = 122
const { ...pet_columns } = getTableColumns(pets) 
const [ pet ] = await db
    .select({ ...pet_columns, owner_name: owners.name })
    .from(pets)
    .innerJoin(owners, eq(pets.owner_id, owners.id))
    .where( eq(pets.id, pet_id) )
    .limit(1)
