Update only specific column

I’m using DBFlow 4.0.0-beta1

I have model:

@Table(database = MyDatabase.class, name = “hero”) public class Hero extends BaseModel{

@Column(name = "id")
@PrimaryKey
private int id;

@SerializedName("code")
@Column(name = "code")
private String code;

@SerializedName("name")
@Column(name = "name")
private String name;

public int getId() {
    return id;
}

public void setId(int id) {
    this.id = id;
}

public String getCode() {
    return code;
}

public void setCode(String code) {
    this.code = code;
}

public String getName() {
    return name;
}

public void setName(String name) {
    this.name = name;
}

}

I’m insert value Hero hero = new Hero(); hero.setId(390); hero.setCode(“823kjh12u3i1k2j3k1j2kj1h2jk32j3kj1h”); hero.setName(“TARFIRE”); hero.save();

Im trying to update only name column

Hero hero = new Hero(); hero.setId(390); hero.setName(“TARFIRE”); hero.update();

but i had code column to be null in my row table

I’m i missing something?

the idea behind this is upsert. But event native sqlite not support this. Just have replace function that set code column to be null when you dont operate

1. select -> replace or
2. select -> update to bring existing data

I get this example from this, I have not used dbflow for a long time. Hope it help https://agrosner.gitbooks.io/dbflow/content/SQLiteWrapperLanguage.html

// Native SQL wrapper SQLite.update(Ant.class) .set(Ant_Table.type.eq(“other”)) .where(Ant_Table.type.is(“worker”)) .and(Ant_Table.isMale.is(true)) .async() .execute(); // non-UI blocking

what I do is create a new table for each variable that is optional.
