「テーブルMYDATABASE_TABLEにはT4という名前の列がありません」というエラーが表示され続けます明らかに、「T4」の変数名であるTIME_4という名前の列があります

次に、ここに値を挿入します。

public long insert(String name, String category, String color, String type, String ingredient1,
                        String ingredient2, String ingredient3, String ingredient4, String ingredient5,
                        String ingredient6, int time1, int time2, int time3, int time4, int time5){

        ContentValues contentValues = new ContentValues();
        contentValues.put(DRINK_NAME, name);
        contentValues.put(DRINK_CATEGORY, category);
        contentValues.put(DRINK_COLOR, color);
        contentValues.put(DRINK_TYPE, type);
        contentValues.put(INGREDIENT_1, ingredient1);
        contentValues.put(INGREDIENT_2, ingredient2);
        contentValues.put(INGREDIENT_3, ingredient3);
        contentValues.put(INGREDIENT_4, ingredient4);
        contentValues.put(INGREDIENT_5, ingredient5);
        contentValues.put(INGREDIENT_6, ingredient6);
        contentValues.put(TIME_1, time1);
        contentValues.put(TIME_2, time2);
        contentValues.put(TIME_3, time3);
        contentValues.put(TIME_4, time4);
        contentValues.put(TIME_5, time5);
        //  contentValues.put(TIME_6, time6);

        return sqLiteDatabase.insert(MYDATABASE_TABLE, null, contentValues);
    }

誰が私が間違っているのか教えてもらえますか? 私はSQLiteが初めてです

変化する

  + TIME_3 + " TEXT, " + TIME_4 + "TEXT, "

に

+ TIME_3 + " TEXT, " + TIME_4 + " TEXT, "

TIME_4 と の間にスペースを入れるのを忘れているためTEXT,
