sqliteが常に最初の値を挿入するループ

Question

私は投票アプリケーションを作成しています。ユーザーは各候補の間にカンマですべての候補を入力し、Enterキーを押して候補を投票します。

def newVote(event): 
       pos = position.get() 
       candidates = addCandEntry.get() 
       formatted = [x.strip() for x in candidates.split(',')] 
       for x in formatted: 
        c.execute("INSERT INTO current VALUES(?, ?, ?)", (pos,x,0,)) 
        c.execute('SELECT * FROM current WHERE position="Chief"') 
        print(c.fetchone()) 

私は位置dad,mom,son,sister,grandmaためのTkinterのエントリに次の値を渡すとしたらそれは

('Chief', 'dad', 0) 
('Chief', 'dad', 0) 
('Chief', 'dad', 0) 
('Chief', 'dad', 0) 
('Chief', 'dad', 0) 

がどのように私はそれだけで最初の代わりにそれぞれの値を追加することができますSQLでこの出力を与えるだろう1？

はここで、あなたが常に最初の行('Chief', 'dad', 0)を返しますfetchone()を使用しているので、あなたがそれ

Answer 1

が必要な場合は、完全なコードです。しかし、フェッチに関係なく、のお父さん、お母さん、息子、姉妹、おばあちゃんの5つの別々のレコードがテーブルに追加されているはずです。あなたは、整数のプライマリを使用する場合に可能である各挿入後、最後の行を取得するためのもののようにしかし、それはそう

for x in formatted: 
    c.execute("INSERT INTO current VALUES(?, ?, ?)", (pos,x,0,)) 

for row in c.execute('SELECT * FROM current WHERE position="Chief"'): 
    print(row) 

：あなたは、各挿入をコミットして、別々のループで出力currentの各行を調整を考えてみましょうキー、各レコードに自動インクリメントid：

あなたは、インサート列を一覧表示するには、強制的

c.execute('''CREATE TABLE IF NOT EXISTS users(
      id integer primary key, username text, password text, admin boolean)''') 
c.execute('''CREATE TABLE IF NOT EXISTS positions(
      id integer primary key, position text)''') 
c.execute('''CREATE TABLE IF NOT EXISTS current(
      id integer primary key, position text, candidate text, votes int)''') 
c.execute('''CREATE TABLE IF NOT EXISTS past(
      id integer primary key, date DATE, position text, candidate text, 
      votes int, winner boolean)''') 

：

c.execute("INSERT INTO users (username, password, admin)" + 
      " VALUES('admin', 'VoteProgram', 'yes')") 

その後、fetchone()を使用することができます：

for x in formatted: 
    c.execute("INSERT INTO current (position, candidate, votes) VALUES(?, ?, ?)", (pos,x,0,)) 
    c.execute('SELECT * FROM current WHERE id = (SELECT Max(sub.id) FROM current sub)') 
    print(c.fetchone())
