我已经尝试过常见的PostgreSQL答案,但似乎它不适用于Redshift:

SELECT  * FROM VALUES (1) AS q (col1);

ERROR: 42883: function values(integer) does not exist

我需要这个因为某些原因我无法使用UNION ALL.任何帮助将不胜感激.

我有一个express应用程序,我正在连接到我的Postgres数据库.这是我的代码:

var express = require('express');
var app = express();
var pg = require('pg').native;
var connectionString = process.env.DATABASE_URL || 'postgres://localhost:5432/isx';
var port = process.env.PORT || 3000;
var client;


app.use(express.bodyParser());

client = new pg.Client(connectionString);
client.connect();

app.get('/users', function(req, res) {
  'use strict';
  console.log('/users');
  var query = client.query('SELECT * FROM users');
  query.on('row', function(row, result) {
    result.addRow(row);
  });
  query.on('end', function(result) {
    console.log(result);
    res.json(result);
  });
});

我去当地Postgres看看isx数据库,这里有可用的表格.

          List of relations
 Schema |   Name   | Type  |  Owner
