如何在量角器+ VSCode中获取sql输出

Question

我运行下面的代码似乎连接成功但我没有看到任何输出或有任何方式来查看查询结果的输出，我是这个量程器nodeJS MSSQL连接的新手。

const assert = require("../configuration.js");
const { config } = require("dotenv");
const { ConnectionPool } = require("mssql");
var sql = require('mssql');

config();

const c = {
  driver: 'msnodesqlv8',
  server: "server/nameORIP",
  user: "UserName",
  password: "Password",
  database: 'DBname',
};

describe("mssql connection", () => {

  it('test query', () => {

    sql.connect(config, (err) => {

      if (err) console.log(err);

      // create Request object
      var request = new sql.Request();

      // query to the database and get the records
      request.query('select * from NetUsers', (err, recordset) => {

        if (err) console.log(err)
        // send records as a response
        request.send(recordset);
      });

    }); // end of sql.connect()

  }) // end of it
})

产量

Request {
  _events: [Object: null prototype] {},
  _eventsCount: 0,
  _maxListeners: undefined,
  canceled: false,
  _paused: false,
  parent: [Function: ConnectionPool],
  parameters: {},
  rowsAffected: 0 }

Answer 1

我没有从他们的官方文档中找到有关方法request.send(recordset);的任何信息。

Request Object中支持的方法是：

1. 执行 - https://www.npmjs.com/package/mssql#execute
2. 输入 - https://www.npmjs.com/package/mssql#input
3. 输出 - https://www.npmjs.com/package/mssql#output
4. 管 - https://www.npmjs.com/package/mssql#pipe
5. 查询 - https://www.npmjs.com/package/mssql#query
6. 批次 - https://www.npmjs.com/package/mssql#batch
7. 散装 - https://www.npmjs.com/package/mssql#bulk
8. 取消 - https://www.npmjs.com/package/mssql#cancel

request.query函数将为您提供数据库中的记录列表，并将其传递给回调函数，并且可以使用直接访问值

request.query('select * from NetUsers', (err, resultArray) => {
    if (err) console.log(err)
    // if no error
    console.log(resultArray.recordset[0]); //will print the first row from response.
  });

我终于让它工作了几个变化，不仅它连接，而且运行查询，并在控制台显示输出，再次感谢您的所有帮助。

import { async } from "q";
const sql = require('mssql/msnodesqlv8');
const assert = require("../configuration.js");

const poolPromise = new sql.ConnectionPool({
    driver: 'msnodesqlv8',
    server: "server/nameORIP",
    user: "UserName",
    password: "Password",
    database: 'DBname',
})
.connect()
  .then(pool => {
    console.log('Connected to MSSQL')
    return pool
  })
  .catch(err => console.log('Database Connection Failed! Bad Config: ', err))
;

describe('any test', () => {

    it('verification', async () => {

        try
        {
            const pool = await poolPromise;

            const result = await pool.request()
            .query('SELECT TOP (10) * FROM dbo.NetUsers')

            console.log(result);
        }
        catch(err)
        {
            console.log(err);
        }

    });


});
