SQL lite データベースに 2 つの新しい列を追加しましたが、新しい列の 1 つが作成されていないため、SQL エラーが発生します。同様のエラーが発生している他のスレッドを読み、スペルが正しいことを確認するために再確認しました。

これはプログラムがクラッシュしている場所であるため、問題は私のonCreateにあるようですが、私はそれを理解できないようです。Player_Number 列と Team 列を追加しましたが、Player_Number は作成されていませんが、Team の列は作成されています。

DBAdapter のコードは次のとおりです。

public class PlayerDbAdapter {

private static final String DATABASE_CREATE = "CREATE TABLE Players (_id integer primary key autoincrement, Player_Name text not null, Player_Position text not null, Player_Number text not null, Team text not null);";
private static final String DATABASE_NAME = "Score";
private static final String DATABASE_TABLE = "Players";
private static final int DATABASE_VERSION = 3;
  public static final String KEY_BODY = "Player_Name";
  public static final String KEY_ROWID = "_id";
  public static final String KEY_TITLE = "Player_Position";
  public static final String KEY_NUMBER = "Player_Number";
  public static final String KEY_TEAM = "Team";
private static final String TAG = "PlayerDbAdapter";
  private final Context mCtx;
  private SQLiteDatabase mDb;
  private DatabaseHelper mDbHelper;

  public PlayerDbAdapter(Context paramContext)
  {
    this.mCtx = paramContext;
  }

  public void close()
  {
    this.mDbHelper.close();
  }


  public long createPlayers(String playerName, String playerPosition, String playerNumber, String team)
  {
    ContentValues localContentValues = new ContentValues();
    localContentValues.put(KEY_BODY, playerName);
    localContentValues.put(KEY_TITLE, playerPosition);
    localContentValues.put(KEY_NUMBER, playerNumber);
    localContentValues.put(KEY_TEAM, team);
    try{
        return this.mDb.insert("Players", null, localContentValues);
    } catch (Exception e) {
        Log.e("Juma", e.getMessage());
    }

    return 0;
  }

これは、正しい構文と定数を使用したクエリです...

private static final String DATABASE_TABLE = "Players";
private static final String DATABASE_CREATE = "CREATE TABLE "+DATABASE_TABLE+" (_id integer primary key autoincrement, Player_Name text not null, Player_Position text not null, Player_Number text not null, Team text not null);";
