使用nodejs连接达梦数据库，参照eco的nodejs文档，查询数据库返回的数据出错。
nodejs代码如下：

// 引入 dmdb 包
var db = require('dmdb');
var fs = require('fs');
var pool, conn;
var http = require('http');
async function example() {
    try {
        pool = await createPool();
        conn = await getConnection();
        await query();
    } catch (err) {
        console.log(err);
    } finally {
        try {
            await conn.close();
            await pool.close();
        } catch (err) {}
    }
}
example();
/* 创建连接池 */
async function createPool() {
    try {
        return db.createPool({
            connectString: "dm://SYSDBA:SYSDBA@localhost:5237?autoCommit=false&loginEncrypt=false",
            poolMax: 10,
            poolMin: 1
        });
    } catch (err) {
        throw new Error("createPool error: " + err.message);
    }
}
/* 获取数据库连接 */
async function getConnection() {
    try {
        return pool.getConnection();
    } catch (err) {
        throw new Error("getConnection error: " + err.message);
    }
}
/* 查询 */
async function query() {
    try {
        var sql = "SELECT TEST1 FROM SYSDBA.T2";
        var result = await conn.execute(sql, [], { resultSet: true });
        var resultSet = result.resultSet;
        // 从结果集中获取一行
        result = await resultSet.getRow();
    while (result) {
        console.log(result);
        result = await resultSet.getRow();
        }
    } catch (err) {
        throw new Error("queryWithResultSet error: " + err.message);
    }
}

数据库表结构如下：

TEST1字段的内容如下：

使用node test.js命令运行文件

返回的结果是一大段json格式的数据，数据是存放在iLob的data里面，这又是为什么呢？
