-- This is a simple schema for keep track of tasks and whether they are done

-- this serves to both declare the table and create the schema
create proc todo_create_tables()
begin

  create table if not exists tasks(
    description text not null,
    done bool default false not null
  );

end;

-- adds a new not-done task
create proc todo_add(task TEXT NOT null)
begin
  insert into tasks values(task, false);
end;

-- gets the tasks in inserted order
create proc todo_tasks()
begin
  select rowid, description, done from tasks order by rowid;
end;

-- updates a given task by rowid
create proc todo_setdone_(rowid_ integer not null, done_ bool not null)
