Connector/c++ 查询Mysql,出现 can't fetch because not on result set 错误
使用 Connector/C++ 查询 Mysql 时,出现错误,提示如下:
can't fetch because not on result set,
出现原因可以看这里:http://stackoverflow.com/questions/17294611/sqlinvalidargumentexception-mysql-c
意思就是,每次读取 resultset里面的内容前,你都需要 调用一次 next()
像这样:
// 输出结果 while(result->next()) { int id = result->getInt("id"); string name = result->getString("name"); cout<<"testuser: "<< id <<" , "<<name<<endl; }
