Question

我正在尝试将以下查询插入到SQL Server中。我对C ++有点陌生。如果有人可以为我提供有用的资源，或者给我提供解决方法。我将不胜感激。

Insert into SInvoice  Values('SIV-2',0,1,1,5.000000,0.000000,'04/01/2019 08:49:46',8.000000,40.000000,'',0,1,1,1,1,'04/01/2019 08:49:46','',1.000000,1,0,'','b',0.000000,5,0.000000,40.000000,'Nos',1.000000,'','','','','','','','','','','','','','','','','','','','','',0,3,'SIV-',1,1,1,1,1,1,3.330000);

使用c ++。我尝试从中获取数据，并且成功了。我真的没有找到关于插入的信息。

这是获取数据的c ++代码。哪个有用。

                cout << name << endl;

            }
        }
    }

    while (FALSE);

    SQLFreeHandle(SQL_HANDLE_STMT, SQLStatmentHandle);
    SQLDisconnect(SQLConnectionHandle);
    SQLFreeHandle(SQL_HANDLE_DBC, SQLConnectionHandle);
    SQLFreeHandle(SQL_HANDLE_ENV, SQLEnvHandle);



    return 0;
}

如何使其执行上面的以下查询。谢谢。
