I have a content type with a field_maps whose type is Text (plain, long). I needed to change it to Text (plain).
So I've done this SQL statement:
ALTER TABLE node__field_maps MODIFY field_maps_value VARCHAR(200);
It seems that field_type has changed to
VARCHAR(200), but there is still one more problem: On the content type and manage fields tabs, the field is still shown as Text (plain, long).
How do I change it to Text (plain)?
