E/SQLiteLog：（1）靠近「，」：語法錯誤

Question

我不知何故無法創建新表。我檢查了我的語法並搜索了其他有相同錯誤的人，但我找不到錯誤。

private static final String DATABASE_NAME = "food_database"; 
private static final String TABLE_NAME = "food_table"; 
private static final String UID = "_id"; 
private static final String CALORIE_COLUMN = "Calorie"; 
private static final String FOOD_COLUMN = "Food"; 
private static final int DATABASE_VERSION = 4; 
private static final String CREATE_TABLE = "CREATE TABLE "+TABLE_NAME+" ("+UID+" INTEGER PRIMARY KEY AUTOINCREMENT, "+CALORIE_COLUMN+" FLOAT , "+FOOD_COLUMN+" text not null);"; 
private static final String DROP_TABLE = "DROP TABLE IF EXISTS "+TABLE_NAME; 

private Context context; 

public FoodHelper(Context context) { 
    super(context, DATABASE_NAME, null, DATABASE_VERSION); 
    this.context = context; 
} 

@Override 
public void onCreate(SQLiteDatabase sqLiteDatabase) { 
    try { 
     sqLiteDatabase.execSQL(CREATE_TABLE); 
    } catch (SQLException e) { 
     Log.e("HEY","Error creating"); 
     e.printStackTrace(); 
    } 

}

有SQLite中沒有datatype叫FLOAT！

只需將Float替換爲REAL！
