嗨，我遇到了一个occi问题，我想从oracle获取间隔值，但它是核心转储，为什么？

Answer 1

最简单的代码是

​

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的一种类型：：occi：：ResultSet* m_colBufi is alloc(colWidthi * fetchsize)，它在以下位置崩溃：

​

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