安裝

npm install tedious

示例代碼

var Connection = require('tedious').Connection;  
    var config = {  
        server: 'your_server.database.windows.net',  //update me
        authentication: {
            type: 'default',
            options: {
                userName: 'your_username', //update me
                password: 'your_password'  //update me
            }
        },
        options: {
            // If you are on Microsoft Azure, you need encryption:
            encrypt: true,
            database: 'your_database'  //update me
        }
    };  
    var connection = new Connection(config);  
    connection.on('connect', function(err) {  
        // If no error, then good to proceed.
        console.log("Connected");  
    });
    
    connection.connect();

Express中集成數(shù)據(jù)庫

Express中集成數(shù)據(jù)庫比較方便朽肥，具體可參考Express中文網(wǎng)的數(shù)據(jù)庫集成：Express-Database integration

使用tedious連接數(shù)據(jù)庫

// 封裝 tedious
const { Connection, Request } = require('tedious')

const config = {
  server: 'your_server.database.windows.net', // 數(shù)據(jù)庫地址
  authentication: {
    type: 'default',
    options: {
      port: 1433, // 端口號
      userName: 'your_username', // 用戶名
      password: 'your_password', // 密碼
    },
  },
  options: {
    encrypt: true,
    database: 'test', // 數(shù)據(jù)庫名
  },
}

const querySQL = (sql, callback) => {
  let connection = new Connection(config)
  var rows = []
  connection.connect()
  connection.on('connect', err => {
    if (err) {
      callback({ message: err['message'] })
    } else {
      let request = new Request(sql, (err, rowCount) => {
        if (err) callback(err)
        callback(err, rows)
        connection.close()
      })
      let i = 0
      request.on('row', columns => {
        rows[i] = {}
        columns.forEach(column => {
          rows[i][column.metadata.colName] = column.value
        })
        i++
      })
      connection.execSql(request) //執(zhí)行sql語句
    }
  })
}

module.exports = {
  querySQL: querySQL,
}

// 使用 tedious
const { querySQL } = require('./index')
querySQL(
    "select 42, 'hello world'",
    (err, data) => {
      if (!err) {
        console.log(data) // 打印數(shù)據(jù)
      } else {
         console.log(err) // 打印錯誤
      }
    }
  )
