You can declare that a variable can be any of **several types**, for example, an `int` or a `str`.

To define it you use the <dfn title='also called "bitwise or operator", but that meaning is not relevant here'>vertical bar (`|`)</dfn> to separate both types.

This is called a "union", because the variable can be anything in the union of those two sets of types.

	if beforeUpdateCall != 1 {
		t.Fatalf("before update should be called")
	}

	err = DB.Model(Product5{}).Where("id", p.ID).Update("name", "update_name_2").Error
	if !errors.Is(err, gorm.ErrInvalidValue) {
		t.Fatalf("should got RecordNotFound, but got %v", err)
	}
	if beforeUpdateCall != 1 {
		t.Fatalf("before update should not be called")

The word **process** is normally used in a more specific way, only referring to the thing that is running in the operating system (like in the last point above):
