如何使用OCI向正在插入CLOB的条目添加回车符/换行符？

OCIEnv *envhp;  // OCI环境句柄
OCISvcCtx *svchp;  // OCI会话句柄
OCILobLocator *clob;  // CLOB变量句柄

// 创建OCI环境和会话
OCIEnvCreate(&envhp, OCI_DEFAULT, NULL, NULL, NULL, NULL, 0, NULL);
OCIHandleAlloc(envhp, (void**)&svchp, OCI_HTYPE_SVCCTX, 0, NULL);

// 连接到Oracle数据库
OCILogon(envhp, errhp, &svchp, "username", strlen("username"), "password", strlen("password"), "dbname", strlen("dbname"));

// 分配CLOB变量
OCIDescriptorAlloc(envhp, (void**)&clob, OCI_DTYPE_LOB, 0, NULL);

// 插入回车符/换行符的数据
char *data = "This is a line of text.\r\nThis is another line of text.";

// 写入数据到CLOB变量
OCILobWrite(svchp, errhp, clob, &bytes_written, 1, data, strlen(data), OCI_ONE_PIECE, NULL, NULL, 0, SQLCS_IMPLICIT);

// 提交事务
OCITransCommit(svchp, errhp, OCI_DEFAULT);

// 释放资源
OCIDescriptorFree(clob, OCI_DTYPE_LOB);
OCIHandleFree(svchp, OCI_HTYPE_SVCCTX);
OCIHandleFree(envhp, OCI_HTYPE_ENV);
