我在我的应用程序上使用 SQLite，我正在创建一些表，这里是代码：

    db.execSQL("CREATE TABLE IF NOT EXISTS " + GAMES_HISTORY_TABLE+ " (" +
        GAME_KEY + " INTEGER PRIMARY KEY AUTOINCREMENT, " + 
        RIGHT_DRILLS + "INTEGER NOT NULL, " + 
        NUM_OF_DRILLS + "INTEGER NOT NULL, " + 
        GAME_DATE + "DATE);"
   );

这是添加记录的代码：

public long addScore(int totalDrills, int numberOfRightDrills) {
    ContentValues cv = new ContentValues();
    cv.put(RIGHT_DRILLS, numberOfRightDrills);
    cv.put(NUM_OF_DRILLS, totalDrills);
    Date date = new Date();
    SimpleDateFormat dateFormat = new SimpleDateFormat("dd-MM-yyyy HH:mm:ss");
    cv.put(GAME_DATE, dateFormat.format(date));
    return dataBase.insert(GAMES_HISTORY_TABLE, null, cv);

}

这是常量变量声明（在我的代码开头）：

private static final String GAMES_HISTORY_TABLE = "scoers";
private static final String GAME_KEY = "game_id";
private static final String RIGHT_DRILLS = "number_of_rihgt_drill";
private static final String NUM_OF_DRILLS = "total_drill";
private static final String GAME_DATE = "game_date";

我在 logCat 中得到了这个异常：

我试图更改字段的名称和表的名称。我在这个数据库中有另一个表。

我做错什么了？谢谢！

您需要在表架构中添加三个空格，然后重新构建它：

db.execSQL("CREATE TABLE IF NOT EXISTS " + GAMES_HISTORY_TABLE+ " (" +
    GAME_KEY + " INTEGER PRIMARY KEY AUTOINCREMENT, " + 
    RIGHT_DRILLS + " INTEGER NOT NULL, " +  /* Add a space before "INTEGER... */
    NUM_OF_DRILLS + " INTEGER NOT NULL, " + /* Add a space before "INTEGER... */ 
    GAME_DATE + " DATE);"                   /* Add a space before "DATE... */
);

（仅供参考，GAMES_HISTORY_TABLE显然是"scoers"，我认为这是错字。）

不确定这是否是唯一的错误，但是在创建表时常量之后但在恢复字符串之前缺少空格：

RIGHT_DRILLS + "INTEGER NOT NULL, " + 
NUM_OF_DRILLS + "INTEGER NOT NULL, " + 
GAME_DATE + "DATE);"

应该：

RIGHT_DRILLS + " INTEGER NOT NULL, " + 
NUM_OF_DRILLS + " INTEGER NOT NULL, " + 
GAME_DATE + " DATE);"
