SQLitedatabaseエラー "SQLite：（1）近く）"：構文エラー "

Question

SQLite：（1）付近の "）"：構文エラー

私は理解していない、私はあらゆるスペース（そしてect）を置くことを思いました（そしてまだやる）

多分誰かが私を助けることができる？

あなたの時間をありがとう

public class DatabaseHandler extends SQLiteOpenHelper {

    private static final int DATABASE_VERSION = 3;
    private static final String DATABASE_NAME = "rekordai";
    private static final String TABLE_REKORDAI = "rekordai";

    private static final String KEY_ID = "id";
    private static final String KEY_REKORDAI = "rekordai";

    public DatabaseHandler(Context context){
        super(context, DATABASE_NAME, null, DATABASE_VERSION);
    }

    @Override
    public void onCreate(SQLiteDatabase db) {
        String CREATE_REKORDAI_TABLE = "CREATE TABLE " + TABLE_REKORDAI + " ( " 
                + KEY_ID + " INTEGER PRIMARY KEY, " + KEY_REKORDAI + " TEXT," + " ) ";
        db.execSQL( CREATE_REKORDAI_TABLE );
    }

私は上記の間違いをした（oncreateメソッド）...

もう一度ありがとう！ そして、私は本当に大分なコード

を申し訳ありません。

Answer 1

あなたの問題はここにあるCREATE TABLE SQL COMMAND

  + KEY_ID + " INTEGER PRIMARY KEY, " + KEY_REKORDAI + " TEXT," + " ) ";// remove semi column after TEXT 

.

下記の

の正しいCREATE TABLE SQL COMMAND

 String CREATE_REKORDAI_TABLE = "CREATE TABLE " + TABLE_REKORDAI + " ( " 
            + KEY_ID + " INTEGER PRIMARY KEY, " + KEY_REKORDAI + " TEXT" + " ) ";

.
