int f1,f2;
MYSQL_RES *res;
MYSQL_ROW row;
cstring strSql = "select field1,field2 from mytable";

mysql_query(&m_pDBConn, strSql);
res = mysql_store_result(&m_pDBConn);
row = mysql_fetch_row(res);
。。。。
在mysql 5.01的c/c++ API中为什么不能这样:
f1 = row["field1"];
f2 = row["field2"];

而必须这样呀?
f1 = row[0];
f2 = row[1];
