oracle讀取ip_num用uint32_t接收，出錯及解決

start_ip_num = rset->getNumber(1);
end_ip_num = rset->getNumber(2);
2988 info_log("GetIpLibraryFromOracle data rset [%zu,%zu,%d]\n",rset->getNumber(1),rset->getNumber(2),rset->getNumber(3));
src/ResultToDB.cpp:2988: warning: cannot pass objects of non-POD type ‘class oracle::occi::Number‘ through ‘...‘; call will abort at runtime 

 

 

ip_num是ip轉成數位32位不帶正負號的整數。我用uint32_t 來接收從oracle讀取的start_ip_num 和end_ip_num ，然後列印到Log裡。結果是[3395598328,46913028405240,242]，第一個數是正確的，第二個是錯誤的，原本第一個數和第個二數要相同（資料庫裡是相同的）。

uint32_t start_ip_num = 0;
uint32_t end_ip_num = 0;
start_ip_num = rset->getNumber(1);
end_ip_num = rset->getNumber(2);
int departid= rset->getNumber(3);

第一個rset->getNumber(1)對了，rset->getNumber(2);錯了

 

用uint64_t 接收就第一個數和第個二數相同。

為什麼用uint32_t 第一個是對的，用uint64_t 兩個都是對的？？我目前還沒有找出答案!
