嗨，我遇到了occi問題，我想從oracle獲取間隔值，但這是核心轉儲，為什么？

Answer 1

最簡單的代碼是

 if (ttype == oracle::occi::OCCI_SQLT_INTERVAL_YM) { LOG(INFO) << "set YM buffer"; m_res->setDataBuffer(i + 1, m_colBuf[i], ttype, 5, &(m_resultInfos[i].fieldLens[0]), &(m_resultInfos[i].fieldFlags[0]), &(m_resultInfos[i].fieldRCs[0])); } else if (ttype == oracle::occi::OCCI_SQLT_INTERVAL_DS) { m_res->setDataBuffer(i + 1, m_colBuf[i], ttype, 11, &(m_resultInfos[i].fieldLens[0]), &(m_resultInfos[i].fieldFlags[0]), &(m_resultInfos[i].fieldRCs[0])); } 

m_res是oracle :: occi :: ResultSet *的一種* m_colBuf [i]是alloc（colWidth [i] * fetchsize），它在以下位置崩潰：

  if (0 == m_res->next(m_fetchSize)) { LOG(INFO) << "Oracle Fetch finished!"; break; }
