csv表格到postgresql数据库与nodejs

嘿，我不能在nodejs中实现函数什么可以从csvparsing数据到postgresql表。 你能帮助解决这个问题吗？

我正在尝试使用csv-stream库，并可以在控制台中获取数据，但如何做一个导入postgresql不知道。

var csvStream = csv.createStream(options); fs.createReadStream(process.argv[2]).pipe(csvStream) .on('error', function (err) { console.error(err); }) .on('data', function (data) { // outputs an object containing a set of key/value pair representing a line found in the csv file. // console.log(data); }) .on('column', function (key, value) { // outputs the column name associated with the value found // console.log('#' + key + ' = ' + value); console.log('# ' + value); }) 

UPDATE

 var pg = require("pg"); var conString = "pg://admin:guest@localhost:5432/Employees"; var client = new pg.Client(conString); client.connect(); var query = client.query("SELECT firstname, lastname FROM emps ORDER BY lastname, firstname"); 

现在我怎么能得到这个select查询CSV？

更新0.1

 var pg = require('pg'); var csv = require('csv'); var csvWriter = require('csv-write-stream') var conString = "pg://admin:admin@localhost:5432/labels"; var client = new pg.Client(conString); client.connect(); var sql = "COPY test TO 'personss.csv' DELIMITER ',' CSV HEADER;" var query = client.query("SELECT firstname, lastname FROM test ORDER BY lastname, firstname"); query.on("row", function (row, result) { result.addRow(row); }); query.on("end", function (result) { console.log((result.rows, null, " ")); client.end(); }); 

现在可能我需要在result.row中执行每个循环。
