Hi guys so I'm trying to test how to use databases in android as part of one of my classes, but I'm pretty new to both so most help I found online has gone a bit over my head.

I was wondering how exactly do I update, and delete from the table. Currently I have:

    wk item = new wk();
            item.name = "okay1";
            item.save();

And that adds an item fine.

and in my database it has

public class wk extends Model {
    Table(name = "ToDoItems")
    @Column(name = "Name")

But I try to run

new Delete().from(wk.class).where("Name = ?",2).execute();

Which I'm assuming deletes the value at 2 in the database of Name, but instead it seems to do nothing? I have tried

new Delete().from(wk.class).execute();

Which does definitely delete my table so I know it can delete, but I just want to delete one value.

Pretty much I want to be able to delete that okay1 value.

Answer

Okay I found the answer I had for deleting which is

new Delete().from(wk.class).where("Name = ?","okay1").execute();

And works perfect for me now.
