Can anybody recommend me an SQL documentation tool that I can:
document SQL Server databases;
add comments to generate descriptions of tables, views, stored procedures, functions and their columns, fields and parameters.
Thank you!
Basically two valid contenders, for SQL Server, in my opinion:
Red-Gate SQL Doc
See their online AdventureWorks sample to get an impression of what those docs look like
ApexSQL ApexSQL Doc
Sybase Power Designer, Oracle SQL developer data modeler (it looks strange but it could create data model for mssql)

I am creating a database and I need to create some tables.
I would like to know which software do you use or recommend (preferably free) to generate SQL code from ER diagram.
Not free, but effective: Microsoft Visio.
It has a nice template for ER diagrams complete with relationships, primary key information, etc. I believe that it can both generate the schema in the database as well as create the diagram by pointing it at a database.
We've used Case Studio 2 for years to model a fairly complex schema - it's pretty good. We use it to create scripts for MySQL, Oracle and SQL Server. It is now called Toad Data Modeller: https://www.quest.com/products/toad-data-modeler/ There's a freeware version (not sure how this differs from the paid-for licenced version though)

What are the features that are not available in T-SQL however, they are part of SQL standard. Also, If someone can list nice features that are available in PL/SQL (ORACLE) not currently available in T-SQL (e.g. LAG and LEAD etc.) I know Denali will introduce some of those (like lag and lead) but not sure?
I know there are features (some of those are indeed nice e.g. TOP) available in T-SQL but not part of SQL Standard. I just want to find other side of story.
There really isn't a SQL "standard". However you can get O'Reilly SQL Pocket Guide, it has most of the primary differences between the SQL dialects and is well worth the 15 dollars to get. There are many small differences in between TSQL and Oracle. Too many to list here.

I got following question on an interview:
Which SQL mechanisms allow user to browse tables sequentially?
Cursor is a good example - but I don't think you could really argue that Cursors are truely a part of SQL - rather they just tend to come bolted in with procedural languages used on database servers - like pl/SQL and T-SQL.
You could also make an argument for Recordsets, Dynasets, DataTables and DataViews, but those aren't part of SQL itself either.
They might be referring to ORDER BY with a sequential field on the table, but if so, they've not phrased their question very well...

"CURSOR" might be the word that you should google for.

is there any free SQL formatter tool? I am using http://www.sqlinform.com/ for small queries. It is very good. But free version supports only 100 lines. TORA has the feature but it has many issues and I can not customize everything. Any free Eclipse plugins for this?
SQL Developer from Oracle is free, supports multiple databases (not just Oracle), and lets you configure how SQL is formatted.
e-texteditor have a snippet can do this.

What are the differences between MySQL and Sql server?
What are the parameter to chose between the two?
Several questions here related to DB comparisons of various flavors:
What are the major differences between databases?
https://stackoverflow.com/questions/404776/why-isnt-postgresql-as-widespread-as-mysql
Where to find a good reference when choosing a database?
postgresSQL mysql oracle differences
The paramater to choose between the two is the price tag. How much do you "expect" to pay for your database. If its zero then MySQL is probably good enough for you, if its 10k then SQL Server is probably good enough for you.
As for the actual differences, there are too many to list.
