C# Sql-server on every client - c#

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.

C# connect to MSSQL .mdf DB without Server

How can I ran x86 .net 3.5 Windows Forms app with .mdf database on the computer without SQL Server (for example, XP of common user).
I have found few samples of connection strings, but all of them are contains something like Data Source=.\SQLEXPRESS
Doubt, that user will be having SQLEXPRESS on his computer. I want something like work with Access db - so user could work without even knowing, what's server, only with local file
MSSQL I have chosen instead of Access, because in the future I can add publish DB on server, but not now.
Maybe, I should use SQLLite, but how in that case?
Thanks.
How can I ran x86 .net 3.5 Windows Forms app with .mdf database on the computer without SQL Server?
This question has very simple answer - you can't!
You must distribute and install some version/edition of SQL Server with your application, otherwise the .mdf file will be nothing more than waste of disk space. You can install SQL Server along with your app. For more information you can see Install SQL Server from the Command Prompt and Install SQL Server using a configuration file. If this is a simple app working locally on a single workstation, you may want to consider using SQL Server Express LocalDB.
Another option is to use different database engine, which has easier deployment and embedding - SQLite, Firebird Embedded, etc. Pick one that you like. Most of these solutions require only to distribute one DLL/assembly with your application. You will not get the full power of SQL Server, but for most apps, it isn't needed anyway.

Do I have to install sql server on each client to use my disk top application?

I have a disk top application made by c# visual studio. My question is do I have to setup SQL server on each client to use my application? or there is another way to attach my database with my application and compress it as one and send to each client and those just extract that file and use the application correctly?
On a real scenario, your database should be placed on a remote server and the clients should only access the database through your API (that will need to support authentication or any other identity based systems).
If your application only needs to store some local information (relevant only for your client app), then you can just use LocalDB or AppSettings, depending on your data structure.
Otherwise, if your application contains more complex features, then you will need an API and a remote DB managed only by you.
To conclude, you only need to setup Sql Server once, when you want to create the design of it (tables, columns, links). The clients will only have to connect to it and pull their data. And this task can be done without installing SqlServer. This link shows you that you only need System. Data assembly to connect to a Sql Server DB.
Yes you need to instal SQL server on each machine or if you go for LocalDB then also u need to instal SQL server engine ,and you have a better option u need to buy sqlserver from AZURE (it's free for one month try if want click here AZURE)

Database to use when creating an installer for your c# 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.

application with setup file with out SQL Server database

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.

Database access on other machine

I'm working on a program that will work very nicely with a database structure and using mysql. I could easy do this with a common server and common database. However I'm looking for a way to have my client(s) use the program on an offline machine without having to install any database managing software.
Basically I want the installation to set up the necessary tables on their machine and have them fill in the database with information relevant to them. Before I start though I wanted to know if this was possible to connect to and manage a database through a C# application with out installing sql software.
You could consider using SQL Server Compact Edition.
SQLite is another option.
Both of these can be deployed with your application and need no separate configuration.
Yes. It is possible. How to do it exactly depends on the database connection approach you're using. For example, this approach shows how to use DataReaders. That's a very old approach. Modern approaches are recommended to use LINQ to SQL, which can be configured to access remotely by setting up a DataContext to point to an external resource.
Basically, wherever you can define a connection string to connect to a DB, you can make that string point locally or externally. An external resource must obviously be available through some URL in order to connect, of course.
You can not connect to a mysql database without installing mysql.
However you can use in process database like sqlite or Compact SQL. They are not traditional server, but rather a library that keeps the database in a local file.
