Order of learning JavaScript, XML & SQL

I am planning to learn the three languages JavaScript, XML & SQL.
Please Suggest me in what order should i learn them.
Also, what are the Software requirements for SQL ?
I generally write my Code in Visual studio, do i need to get something else for SQL?
Ans lastly, are SQL & MySql different?

Thanks for taking time out

 

A friend uses Microsoft SQL Server 2005 to write code in ASP.NET, C#, and SQL. It's my understanding that SQL Server 2005 can be dowloaded for free, in a "starter" version, from microsoft.com.

I would learn SQL, XML and JavaScript in that order.

SQL and MySQL are different. MySQL works exclusively with PHP, another server languge. .NET is also a server language. The query syntax for SQL and MySQL are virtually the same, however.

A server cannot run both PHP/MySQL and .NET, it's one or the other.

 

Thanks for the info
I had all plans of doing it in the reverse order

 

Javascript and Mysql can be learnt together.

 

SQL and MySQL are different, but not because MySQL only works exclusively with php (which isn't true), but because SQL is not a server, but a language. SQL stands for Structurized Query Language. MySQL is a server that uses SQL to comunicate with other scripts.
MySQL works with everything, as long as the language has support for it. I think it works with almost any language: ASP, PHP, Python, Java,...

don't you mean can't. Javascript hasn't got the capabilities to connect to a database. Whenever you need access to a database for a javascript script, you need to use AJAX to comunicate with a serversided language that will grab the content from the database

 

i would learn xml first to understand elements and dom. then sql and javascript.
