我试图在sqlite数据库中插入值，但它显示一个错误，指出无法将值插入数据库没有找到这样的表。即使我尝试更改数据库版本并卸载应用程序并再次安装它但是它没有用。
数据库：
public class BuisnessDatabaseHandler extends SQLiteOpenHelper {
// Database Version
private static final int DATABASE_VERSION = 1;
// Database Name
private static final String DATABASE_NAME = "receiptExample";
// Labels table name
private static final String TABLE_LABELSS = "buisnesslabels";

private static final String KEY_IMAGE = "image";
private static final String KEY_STATUS="status";
private static final String KEY_UPLOADSTATUS = "uplaodstatus";

map.put(KEY_STATUS,"yes");
label.add(map);
} while (cursor.moveToNext());
}
database.close();
Gson gson = new GsonBuilder().create();
//Use GSON to serialize Array List to JSON
return gson.toJson(label);
}

Log.d("query", updateQuery);
database.execSQL(updateQuery);
database.close();

}
即使我在同一个数据库中有另一个表，但它工作正常我不知道为什么会出现这样的错误。
