Im new to Angular.JS and just wondering if it is possible to write mysql queries in angularjs?
I would like this as I am trying to create a messaging system in which I query the database and get the information live to the webpage.
Any help is appreciated, hope the question is reasonable. Gab
That is not advisable (if possible at all) as it would defeat the purpose of Angular.
You should consume data by targeting a RESTful api/service exposed by the server. The service would handle the DB access for you and provide the data to Angular using a more portable format (e.g. JSON or XML)
Some of the basics of linking Angular and REST are described here
There are related questions on SO about exposing your particular DB flavor using REST here.
This can only be a starting point but it should give you some ideas. I will try to amend this with more info as I come across it.

What are the different techniques to transfer one form data into another form in Angular 2 or in general web development?
Pros/Cons of each technique and when to use what
I have come to know the following different processes -
Using API (i.e. through query params). Example - https://www.jotform.com/help/351-How-to-Automatically-Pass-Form-Data-to-Another-Form
Using HTML5 local storage or session storage
Transfer data from one HTML file to another lists down the options I have mentioned above.
I am a newbie in web development, so my knowledge is limited, but I am willing to handle complex process if that is more efficient than others.
Time to learn about Services before trying to write a working app: https://angular.io/tutorial/toh-pt4
My question is a simple enough one but I can't quite seem to find a good tutorial on it. Maybe I am not being specific enough with what I am asking but I can't really type an explanation into google and expect an answer.
So here is my question;
I currently have a website up and running on a hosting site and this hosting site allows me to have a database up on their server as well.
So my question is how do I read data from this database that I have setup using phpAdmin? Also, it is a mySQL database.
The website will be acting like a review site built I just want to use it to learn web development as well. So What I am trying to do it read articles that I will be saving in the database so I can display them on my website.
Any help or advice in regard to this is much appreciated.
Thanks in advance,

you cant read directly from a Database using AngularJS or any Client-side framework , you need a back-end / server-side language such as PHP ,C# ,Java..
to connect to your MySql ,MSSql... ,
so in your case your need to create PHP script which will connect to the Database and provide an interface you can access with (GET , POST methods ) using AngularJS ($http.post("url"...)
for a best practice (if you want) the Data should be in JSON format.
I know this sounds crazy, but I had a thought and I was willing to try it out. I use GitLab pages for all my online projects, but a lot of them are ASP.NET MVC, which is an issue as I don't think you can run ASP.NET MVC sites on GitLab pages. I then thought, what if I make a site using something like angular or node.js, and have a central API for all my web projects? I thought that was a great idea, until I realized I couldn't use a database either. I guess what I'm asking is, would it be possible to create a REST API that uses JSON files for storage and node.js as the request pages, to create an API without a database?
Of course.
If you think about a database from the perspective of your application code, it is basically just a place to store and retrieve data.
Imagine the database library you are using has two simple methods, store and retrieve. In your application code, you could write db.store('here is the item') and the later on, db.retrieve().
However, those store and retrieve methods could be implemented in many different ways to provide the same effective behavior from the perspective of your application. Some examples:
Send/query the data to/from an external data store, such as PostgreSQL
Write it to a file on disk and read it back later
Store the data in memory
Make HTTP requests to an external system to store the data
Some of these options will be more or less appropriate depending on your exact requirements, however, the general idea is that given a database API, you could implement the exact same method signatures with a completely different approach.
I'm new to webdev and I'm trying to use passport for registration/authentication on a site I'm setting up. I'm also going to write an application in node later on that will be using some of the user data (users will need to provide an API key for an account on another site that I will use to pull data into the application).
At the moment, the main issue I'm having is figuring out what goes where. I've found plenty of resources that explain how to create an app using passport, but nothing shows how it would be incorporated into your website or where the files should be in relation to your website. I'm relatively new to Node.js, and while I've written a few small applications I have never hosted them anywhere.
Bonus question: I'm using MongoDB with passport and I was also planning to use it to store some JSON my application will be receiving from API calls. However, I wanted to use MySQL to store some data as well. More specifically, I'm planning to save the raw JSON then I'll create a relational database out of the data I need from the JSON and then keep the rest in MongoDB for easy access. Is this common/smart, or should I focus on keeping everything in my MongoDB? I'm relatively new to NoSQL.
Thanks in advance for any help.
I would reference this tutorial. I just recently used this to help myself with a new application. Also there is an example of the same thing but in SQL here. So not sure what you mean by " where the files should be in relation to your website". The information related to to authentication should go in your database.
To your "bonus question" you can use two databases. The key here is to ask yourself why and what are the true needs for data, and how is this data accessed and used. From ground up I would like one and stick with it. If at some point later you realize a certain type of data would be better in a different database then you can add it.
Side note: look into an IDE such as webstorm to help you out.
We are very struggled about getting and posting table data for Navistion Database.We need getting data for Navistion DB to our local(sqlLit) DataBase and posting data SqlLit Db to Navistion DB.In PHoneGap
We are goggled.But no luck.So Please give any documentation and link .Please help me.
PhoneGap/Cordova can work with other databases when you use middleware on your server to respond to it. So for example, your server (with the Navistion DB) could use PHP or ColdFusion to respond to Ajax requests from your app. It would handle taking the request, querying the db, and converting the response to JSON. There is no documentation link for this as it is too abstract of a question really.
Agree with Raymond - the question is too general to give any kind of recommendation. Maybe if you could elaborate it a bit - at least outline the task you need to solve, it would be easier to suggest something.
Anyway, I presume, you don't want to insert data into the Navision DB directly, but need an interface to Nav functionality. My first idea would be to look at Web services. Some documentation is available on msdn: Web services in Nav. You can expose Nav objects (Codeunits, Pages and Queries) through a web service and call it from PhoneGap.
