C++ 简单的SQL注入过滤

前几天帮一个客户写了一个C++连接MySQL，当他用到他的游戏中后，被人注射了，用了一个永真式，无限的刷了游戏装备
所以，我针对参数和整体SQL语句写了两个简单的函数，进行简单的过滤。

bool CheckSQL(string sql)
{
    string key[9] = { "%","/","union","|","&","^" ,"#","/*","*/"};
    for (int i = 0; i < 9; i++)
    {
        if (sql.find(key[i]) != string::npos)
        {
            return false;
        }
    }
    return true;
}

bool CheckParameter(string Parameter)
{
    string key[14] = {"and","*","="," ","%0a","%","/","union","|","&","^" ,"#","/*","*/" };
    for (int i = 0; i < 14; i++)
    {
        if (Parameter.find(key[i]) != string::npos)
        {
            return false;
        }
    }
    return true;
}
