i want to learn mysql. what i do for learn it.
Currently i Read books on MySql. any other way for learn it
Just start using it. Build some stuff, play with it, you will run into problems eventually. And then you can use your books (and internet) to solve them.
Well, this site will give you some good execises. Search some of the questions (even if answered) and see if you can follow what eh answers do. See if you can get to the answer without looking ( Dont cheat X-) ).
Ask if you cant find the solution, but dig in, try some of the "LIVe" examples.
Think about some problem domain like a library for example. It will contain books, periodicals, cds, dvds, etc. It will have certain actions like taking out a book, returning a book, issuing library cards, etc. Model this in the database of your choice, and write the sql to extract as much of this information as possible: things like who has overdue books, when will the persons library card expire, how many items are catalogued as comp-sci, etc. You get the idea.
After completing this exercise you will know more sql than most developers !

This sounds very weird, so let me explain in detail:
The way I work in Unity, is I think of what I need to do (such as make a climbing script) then I go
to YouTube or Google to look for a tutorial, but sometimes there's issues with using that code for
any particular reason. All I do is essentially monkey see, monkey do, but I want to start writing code myself instead of relying on a teacher in a video that may or may not reply to questions.
I have gone to the Unity manual and had a look through a lot, but it doesn't show the actual code/command, just explaining general terms for functions in Unity but not the code itself.
I am self-taught and instead of solely relying on videos, I want to just reference from a sort of code-dictionary/summary and figure it out myself. I have spent ages trying to find something like this, but
for the life of me, I cannot find what I need.
I don't know if there's a hidden sub-section of Unity's manual, or if it's solely for explaining terms without showing just the code.
For example, let's say you go to a library and you want to learn Latin, so you go in looking for a translation dictionary, but instead, everything there talks about the history and behaviour of that language, everything except the translation and terminology.
I have tried going by memory and searching when trying to make my own script, but it would make it infinitely easier if there was a summary of all the commands. There should be something like that, that already exists and I think I'm just having an absolute brain-fart over this.
Can anyone help out?
You talked about the Unity Manual. You were almost there! There's also a Unity scripting API. It shows every bits of code you can use in the unity Engine. There's a lot of coding examples on what the scripting components do.

I am trying to make an economy bot for discord using C#. I am confused about how I am going to do it. I might have to use databases but in that case how do I make it so it makes a new line for every user that has used the command. Any help would be nice, thanks.
You need to use a database. If this is your first time using databases, I highly recommened SQLite. You should also see video tutorials such as this one.
Once you have familiarised yourself with a SQLite databases then you will be able to answer your own question extremely easily. It is not difficult and requires some very simple logic. Attempt it yourself first and if you are still stuck reply to this answer.
Consider viewing this W3Schools resource when you are comfortable with the basics.

I would like to scan an economic calendar (and in a second step possibly a news source) like this one for use in MetaTrader/MQL5. I guess I would need another programming language than MQL5 for that, possibly (but not necessarily) C#? (How) can it be done in principle?
Thank you very much in advance!
You can check whether you can access that web page through WebRequest() function available in MT4/5. Alternative way is to write a DLL (or to find one) and access the link above through the REST api (but it doesnt make sense as WebRequest provides it) or somehow else. The easiest way is to check all calendars you may find (myfxbook, mt5.com, fxfactory) and find the easiest page to parse with MT5 methods, then try to collect data and process it. If your skills include some other languages, it might make sense to collect data with REST and then parse it with Jsoup/soup/beautiful-soup (the library that is designed for your language) - that will help with tests (to clear the data faster), and WebRequest() for live.

I recently got an offer for a traineeship for C#.NET. However before being allowed in the traineeship I need to make a small program which displays my programming skills in "C#.net". I don't know what to do now. I've downloaded visual studio 2015 and when I open it I see lots of stuff like console application/windows application etc and even .asp.net applications for web.
In the traineeship document terms are used like " Object Oriëntated, Object Orientated Analysis and Design, UML, Database Design, SQL, XML, Scrum, Javascript, HTML5 CSS3, jQuery, Ajax, Design Pattern (MVC) and WCF.
I don't have a clue where to start! If they wanted ASP websites they could've explicated this right? Should I make them a keygen music mp3 player in a console application? Srs please help. I got 1 week for this.
Usually when asked to perform such task with as vague description as possible, the recruiters want to see your creativity and general knowledge of the technology. You don't have write another Windows system, so it's entirely up to you on what you decide to write. Just make sure it will work and it will follow general coding guidelines and it should be okay :)
I'm sure this is not the place to ask that question. You better go get some tutorials and try to walk your first steps on C# and .NET. As Keran said, the recruiters just want to know your programming and knowledge level of .NET.
Microsoft Virtual Academy is a good place to start.
Have fun!

In a project I have, I want to be able to select a range of products that a customer might want to buy. The range of products should be selected based on patterns of other customers.
I am currently thinking about neural networks, however I am not sure if that is the way to go. Since I am learning about this, I am looking for good examples/tutorials to help me on this.
So far, I was thinking that multi-layer feed-forward neural network would do the trick, but usually the articles are talking about one predicted value, while I am looking for a range of values. The idea that I got is to use the error to calculate the range. Is that the way it is done?
My other approach is more statistical by using probability.
Can anyone point me to the right direction, preferably with C# examples as it is the chosen language to work with?
I can't point you at any tutorials. However, I used to work on the peripherals of this area alongside people who were very experienced in this sort of thing and their opinion was, overwhelmingly, that a probability-based approach is the more cost-effective of the two.
Machine learning of one kind or another is undoubtedly the more powerful technique but it requires a colossal amount of comparative time and effort, and the quality of the results may not prove to be worth the additional resources.
