I faced with problem:
There is a big old database on microsoft sql server (with triggers, functions etc.). I am writing C# app on top of this db. Most of work is a "experiments" like this:
Write a part of functionality and see if it works in old Delphi app (i.e. inserted data in C# loaded correctly in Delphi).
So I need tool, that can determine which fields of each table is used or not (used in my queries). I think to write python script with sql syntax analyser or just using regular expressions.
What solution would you recommend?
You can run a trace in SQL Profiler to see the queries being executed on the server.

How i can add code editor C#,which will compile the code in live
I tried something with Ace, but nothing so far
Thank you.
If I understand correctly, you want to propose an input to user. They had C# code (no matter what) and your server executes it.
If yes, take a look at that.
It creates a project and build it in memory before executing it.
Be careful cause if you execute the code no matter what it will be a security breach into your server. For example, someone could execute a code which will download a file onto your server and open a backdoor to it.

This is embeddable .Net compiler which you could use without any preparations and setups

Right now I am developing C# desktop application for some insurance company. Their reports have a lot of unusual tables with a lot of fields and I have to draw all that tables by using C# drawing class which takes a lot of time.
So I was wondering if there is any tool that can generate C# code for that table after drawing that table using mouse? Or if there is any way I can insert some data in already drawn MS Word table?
You can use COM to write in MS-Word tables:

Microsoft SQL Reporting Services is the best Tool for Reports (if you are already at the microsoft side)

I have a database schema. How do I construct a family tree using asp.NET, C# and SQL server? Also, how can I show you the database schema?
I suggest you take a look at Family Show, a WPF application which enables you to view and/or edit a family tree. I think that with some tweaking you will be able to make it work against SQL Server using your database schema.

I am currently writing a program in C# that will connect to a database for various user data. The query I have at the moment is what would be the best practice to be able to connect to various databases from the program at runtime?
To clarify:
I may want to connect to Oracle R12, or MS SQL Server or maybe even a dumb old access database. I am fine with putting the connection methods into their respective classes, but what I really want is a config file to be packaged with the application which dictates the type of server used for each installation, the field naming convention, etc.
So should this connection file be a .dll? an encrypted text file? or something else?
Obviously I dont want the end user ready access to the connection details in case they try and do their own digging in the database outside of my application.
I would go with encrypted configuration section, it's pretty standard and there are many examples, here is MS documentation:

I'm trying to find some relevant documentation in how to open a connection using the MySQL .NET Connector and then switch databases using the USE command.
The MySQL documentation says, well, nothing. That works for console but how do I actually use this in C# code?
To connect to a MySQL server in C# you use a connectionstring to define the server, the database, the user and the password.
If you want to use multiple databases, you should create a connectionstring for each database.
Look on this site for examples of connectionstrings: http://www.connectionstrings.com/mysql.
