Automatic incremental SQL Script generation for incremental, nightly builds when using Team Build in TFS 2008 and Visual


Tag : sql , By : Kenny

Does that help Try to use SQL Examiner Suite for this: http://www.sqlaccessories.com/SQL_Examiner_Suite/
The tool compares both schema and data and produces synchronization scrips (or differentials scripts). You can automate script creation with supplied command-line tool.

Incremental and non-incremental urls in node js with cheerio and request

I hope this helps . You can find out how to do it by studying existing famous website copiers (closed source or open source)
For example - use trial copy of http://www.tenmax.com/teleport/pro/home.htm to scrap your pages and then try the same with http://www.httrack.com and you should get the idea how they did it (and how you can do it) quite clearly.
var request = require('request');
var cheerio = require('cheerio');
var wait = require("wait.for");

function requestWaitForWrapper(url, callback) {
  request(url, function(error, response, html) {
    if (error)
      callback(error, response);
    else if (response.statusCode == 200)
      callback(null, html);
    else
      callback(new Error("Status not 200 OK"), response);
  });
}

function readBookInfo(baseUrl, s) {
  var html = wait.for(requestWaitForWrapper, baseUrl + '&s=' + s.toString());
  var $ = cheerio.load(html, {
    xmlMode: true
  });

  return {
    s: s,
    id: $('work').attr('id'),
    total: parseInt($('records').attr('total'))
  };
}

function readWorkInfo(id) {
  var html = wait.for(requestWaitForWrapper, 'http://api.trove.nla.gov.au/work/' + id.toString() + '?key=6k6oagt6ott4ohno&reclevel=full');
  var $ = cheerio.load(html, {
    xmlMode: true
  });

  return {
    title: $('title').text(),
    contributor: $('contributor').text()
  }
}

function main() {
  var baseBookUrl = 'http://api.trove.nla.gov.au/result?key=6k6oagt6ott4ohno&zone=book&l-advformat=Thesis&sortby=dateDesc&q=+date%3A[2000+TO+2014]&l-availability=y&l-australian=y&n=1';
  var baseInfo = readBookInfo(baseBookUrl, 0);

  for (var s = 0; s < baseInfo.total; s++) {
    var bookInfo = readBookInfo(baseBookUrl, s);
    var workInfo = readWorkInfo(bookInfo.id);
    console.log(bookInfo.id + ";" + workInfo.contributor + ";" + workInfo.title);
  }
}

wait.launchFiber(main);

Short incremental uinque id for neo4j


Tag : django , By : techthumb
Date : March 29 2020, 07:55 AM
With these it helps First, you should put a unique constraint on the id property to make sure there are no collisions created by parallel create statements. This requires using a label, but you NEED this fail-safe if you plan to do anything serious with this data. But this way, you can have rolling ids for different labels. (All indexed labels will have a count table. UNIQUE CONSTRAINT also creates an index)
Second, you should do the generation and creation in the same cypher like this
MATCH (n:Node) WITH count(*) AS lastId
CREATE (:Node{id:lastId})
