I want my application to create database in the user's computer. The database would be simple, with only one table. Is this possible? What would be in the connection string? Should the user have installed some kind of server?
I suggest you take a look at SQL CE - it is an embedded database which you can distribute with your application.
Microsoft SQL Server Compact (SQL CE) is a compact relational database produced by Microsoft for applications that run on mobile devices and desktops.

I have created a CRUD application that is running really well. It connects to SQL on the same machine. I want to publish my C# app and install it on another PC does not have SQL.
Is it possible to run it on that PC, without installing SQL Server on it? If so, how do I do this?

Without a database your application is "dead".
You have two options.
Install a sql server it this PC.
Connect to a sql server isntalled in another PC.
It's your choice.
If your project is a small one and the database is less than 4GB and you are not going to install SQL Server on every machine and your client do not have access to a Server with SQL Server then you may want to use SQL Server compact
In this case your database would be an single sdf file and you will connect to it using its path on the machine. Then the connection string would be like this:
Data Source=MyData.sdf;Max Database Size=256;Persist Security Info=False;
For more on connection string see this.

I want to build an application that needs a sql database on every machine that uses the application.
Isn't it true that Chrome and Firefox store cookies in a SQL database? I did not remember installing anything like a SQL server while installing Chrome, so my question is: does every user has to install a SQL Server if my app uses one?
The best thing for your purpose is to use database servers, which will be started with your application, like SQLite or Sql Server Compact. That means, you application host the database it self and you have access over ADO.Net. This is a very smart kind of storing local data and very easy.
Do not try to install complex database systems like mssql, sybase or mysql on every client.
For example, SQLite can be delivered with a few assemblies in your product.
This answers gives a nice overview: Lightweight SQL database which doesn't require installation
In order to store information for a client application, you can use SQL Server Compact, or some other solution, like SQLite (with a library to access it).
There are other alternatives, but these two are the most common and stable.
It's true that Firefox stores cookies in a sqlite database. However, that's not the same thing as SQL Server.
If your app needs to communicate with a database, you can a) bundle a sqlite database with it, b) require an existing database on startup (Wordpress does this; you can pass it details for a mysql database to get it to use an existing installation), or c) bundle a full database (like SQL Server Compact) with your application.
I am creating a c# application which requires to use a database and i am also planning to create an installer for my application. I just want to ask which database would be best to use in my application and how do i install it on a user machine while installing my application through installer file.
I have thought of using MYSQL database but for that u need to have MYSQL installed.
Update
i want each user to have there own instance of database when they install the application
You do not have to ship a full database server with your application; only the redistributable runtime which your application would use to connect to the actual database server remotely. In the case of MySQL, you only need the assemblies.
Applications I wrote relied heavily on SQL Server. In order to simplify evaluations and the initial deployment, the installer would install SQL Server Express (installed as an application specific instance). This is an approach I'd recommend if your application is intended to a centralised database.
What is key to understand, especially with commercial application, is that the database engine you install may have to co-exist with existing versions of the respective database engine. That is why application specific instances was created for SQL Server Express.
The alternatives, which are embedded, are:
SQLite.net
SQL Server Compact Edition. The deployment process is well defined.
VistaDB
Embedded databases have some challenges when deployed as part of a server application. For many years, Microsoft refused to allow SQL Server Compact Edition to be used for ASP.NET applications. If the database is per user, per device, an embedded database may be perfect.
Also be aware that MySQL has license restrictions when shipped as part of commercial software (aka you're acting as an OEM, ISV or VAR).
Have a look at SQL Server Express Edition.
It's just a file which you can copy and a class library which allows to access it. And after you finished your installation you can just delete the files (or to keep them if you need them to uninstall the product).
may be u are a fresh.
MYSQL is ok ,but u are creating a C# application,i strongly advise you use mssql
because C# has a close relationship with mssql,develop more convenient.
My advice would be using SQL Azure.
But only if:
You don't need much storage (<1GB).
You don't save sensitive Data there.
Your users have an internet connection.
It's a cloud based Sql Server Database. And the Conneciton is very simple, basically you connect like to any other Database via the Connection String.

I have a windows application which is uses SQL Server as its database. For this application I want to create a setup file for other desktops, but I don't want to install SQL Server on each and every client.
Can you please suggest how to create Windows application with local storage setup file without installing any databases or framework libraries?
You can use SQL Server Compact. The database is stored in a file that you carry with the product rather than requiring a database server.
If this is just for "settings" then consider storing it in the user's application data as a simple XML file.
You don't need to install SQL Server on each client - you can simply install it on a central server then all the clients can connect to and use the same instance.
If this is not a good option because each client must have its own storage locally then you can look to use something like SQL Server Compact, which is a very cut down version of SQL Server that doesn't require installation and runs inproc.
I have a simple code that is using C# and Sqlserver 2008.
For my C# code I get the .EXE file to customer and forced to install the .NET framework on her computer to run just the C# code.
But about the Sqlserver; I have installed the complete Sqlserver on my PC then attached my database on management part of that and am using the Sqlserver
now that I want to get my program to customer I install the .NET framework; but how can I run Sqlserver on her computer and attach the database each time?
Lets me to explain more:
The program will use on a local network and is multi_user.
I installed and am using the Sqlserver on my PC. I created my database and it's tables by help of sqlserver management tool.
for connecting to the datatbase I wrote a code that connect via the users IP address and I tested it on my PC with 2 Virtual machine. It is working truely.
My problem is here:
When I get the program to customer, what I have to do exactly?
What about the database I have to do?
I have to install the whole Sqlserver on customer PC and set that PC as a server or I have a better way to do this?
Thanks.
If you want to use sql server as an embedded database for local storage, use sql server CE.
If you want your users to have access to a shared database you'll have to instal sql server (sql server express may do) on some machine in their network, configure the access rights, and adjust their connection strings accordingly. Or use SQL Azure.

yes you have todo all this work
1)install sql server and the management
2)install your database
3)remote your database to be used
