node.js - Node js 作业从 sql server 获取数据并插入 mysql 数据库

Question

我想在节点 js 中开发一个任务，它从 sql server 中的表中获取数据并插入到 mysql 中的表中。此任务需要在一定时间段后（例如每 5 秒后）连续运行。请指导我实现这一目标。

JS代码

var sql = require('mssql');
var mysql = require("mysql");
var config = {
    user: 'user', 
    password: '*****',
    server: 'url', 
    database: 'DB',
    stream: true //work with large amount of rows
}

var connection1 = mysql.createConnection({
          host     : 'localhost',
          user     : 'root',
          password : 'root',
          database : 'test'
});

connection1.connect();
var connection = new sql.Connection(config, function(err) {

if(err)
    console.log(err);

var request = new sql.Request(connection);
//request.stream = true; // You can set streaming differently for each request 

request.query('select TOP 100000 * FROM ShipmentAuditLog with (nolock)'); // or request.execute(procedure); 
console.time('Time-Taken');

request.on('recordset', function(recordset) {
    // Emitted once for each recordset in a query 
    //console.log(recordset);

});

request.on('row', function(row) {
    // Emitted for each row in a recordset 
    //console.log(row);
    syncing(row);

});

request.on('error', function(err) {
    console.log(err);
});

request.on('done', function(returnValue) {
    // Always emitted as the last one
    console.log('Completed');
    console.timeEnd('Time-Taken');
    connection.close();

    });
});

var syncing = function(row){
 connection1.query('INSERT INTO shipmentauditlog SET ?',row,function(err,res){
     if(err)
        console.log(err);
  
  });
}
