		mCon.Open();

		string dropDBStr = "drop table if exists Scores";
		string createDBStr = "create table Scores (name TEXT,score int)";
		SqliteCommand cmdDrop = new SqliteCommand(dropDBStr, mCon);
		cmdDrop.ExecuteNonQuery();
		SqliteCommand cmd = new SqliteCommand(createDBStr, mCon);
		cmd.ExecuteNonQuery();
		Debug.Log("创建了数据表");
