Error in connecting aspx.cs to database situated in app_data folder [database connection error]
Have you tried localhost as opposed to (LocalDBv11.0), like this? objconn.ConnectionString = "Data Source=localhost;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|test.mdf;User Instance=true;user id=xyz; password=xyz123; Initial Catalog=TEST"; localhost will use TCP, while (LocalDBv11.0) will use Named Pipes

PHP: Not connecting to database
You need to add "" around the fields you are about to insert. You presently have: $query="INSERT INTO user (fname, lname, username, password)"."VALUES('$fname', '$lname', '$username', '$password_hash')"; Do this instead: $query='INSERT INTO user (fname, lname, username, password) '. 'VALUES("'.$fname.'", "'.$lname.'", "'.$username.'", "'.$password_hash.'")';

Connecting to a database in C#
You have an SDF file, meaning that you connect to a Sql Compact not to Sql Server. You need to use the classes in the namespace System.Data.SqlServerCe SqlCeConnection conn = new SqlCeConnection(source); Also, I am not sure of this, but I think you don't need to have single quotes around values in the connection string string source = "Data Source=E:\Documents\Database\MyDatabase.sdf;" + "Password=password;" + "Persist Security Info=False;";

JSP - connecting to a database
Your intuition is right. You should not connect from the JSP directly to the database, if that is even possible. Most programs consist of several layers. For example: You have the DAO (Data Access Object) which has one responsibility: getting data from the database. It does not care what happens with that data, but it retrieves it. Then you have the service layer which does business logic, calculations, etc. It does not care where the data comes from, it just assumes the data is there (but it is from the dao) Then you have the user interface layer which prepares the information to be used in JSP's, does transformations that the JSP cannot do, filter out information that is not required, etc. And once again, it does not know anything about where the data comes from, it just gets it from

connecting to an SQL Server database
The problem your having with regards to connecting to the database on a server is because of SqlConnection dbConnection = new SqlConnection("Data Source=.\SQLEXPRESS;Integrated Security=true"); The best way to do this is to go to your Web.config file and find the block and add a connection to your database in there. eg <add name="ConnectionString" connectionString="Data Source=YOUR SERVER;Initial Catalog=YOUR DATABASE;User ID=YOUR USER ID;Password=YOUR PASSWORD" /> then you can just call the connection string accross your whole project whenever you need to use it. Also with regards to VS2012. There are very few companies using that IDE at the moment so your probably better off learning VS 2010 in the most part but i would agree that VS2008 is fairly out of date now

Connecting to a MySQL database with PDO
First the reason you define config in different file is so that you can just include that file instead of writing the database configuration anytime you want database access. It is preferred best practice. you can do: try { $PDOConnection = new PDO('mysql:host='.DB_HOST.';dbname='.DB_NAME.'', DB_USER, DB_PASS); $PDOConnection->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION); //Do you stuffs $PDOConnection = null; } catch(PDOException $e) { //Do something with error }

Connecting to mysql database with go
connection refused generally means the port isn't open or is being blocked by a firewall. A couple things to check: Is MySQL (on localhost) running? Is it on port 3306? If you're on Windows, Mac or Linux, is there a firewall that might be blocking port 3306? If you're on Linux, is SELinux enabled that might be blocking port 3306?

Connecting to a MySQL embedded database from PHP
As I am aware, the only embedded database which PHP supports is SQLite. In any other ways of trying to connect to MySQL database (with MyISAM engine) you would need either to expect resource from queries, PHP compatible objects, which non of them is the binary format of MyISAM files. At least, Embedded databases are widespread in application programming, not so much in web programming. However, I found something, that converts MyISAM to SQLite http://www.fullconvert.com/MyISAM-to-SQLite/ Managing SQLite with php is simply done by sqlite_ functions which creates files for db's and tables, execute queries, etc. Small tutorial: http://www.techotopia.com/index.php/PHP_and_SQLite PHP SQLite official documentation: http://php.net/manual/en/book.sqlite.php

Connecting to Oracle database(Not XE) without being on network
Your listener has to be configured to listen to your localhost internal interface, 127.0.0.1, for you to be able to connect when not on a network. If it's only configured with your network adapter's IP address you will only be able to connect while on the network. When you unplug your LAN cable the interface associated with that IP is disabled and no longer reachable, even from within your PC. You will also have problems if your IP is allocated by DHCP, and would need to use a DNS name that follows reallocation; that's why servers usually have fixed IPs. You can configure the listener to use both addresses if you need to be able to connect locally when off the network, but have other clients connect to your database when you are on the network. Having a DB that others need to access on a

Not connecting to database from local website
First, ensure that the connection information is correct (server and database name). Then make sure that 'Remote Connections' are enabled in SQL. Also, since it is .Net, you could grab a .Net decompiler (perform a Google search) that will allow you to decompile the DLLs and view the most of the source code. This is probably your last option, but would allow you to at least view what the page is doing and gives you a starting point if you had to redevelop the site.

I'm going to say that you have a quotes error in your insert code. Use escapes, double quotes, or some other mechanism to separate the quoted variables from the quoted string, like so: $insertRow = "INSERT INTO people(fname, lname, age, city) VALUES('$fname', '$lname', '$age', '$city')";

iOS & bootstrap connecting to external database
You are correct. To get data from an external database you will need to make a webservice call To a script that returns the data you wish to use. You can get the data back in JSON or XML format. I prefer JSON as I think it is easier and simpler. AJAX would be a good way to make calls for your data. Its a good idea to make a mix of both. You can use and webserver to store all your data but if the user is in an area that they can't use data then it would render your app useless. Normally I keep all the data I need on a server then download and store it in the apps DB for that user. You can then make a request to the server at intervals to see if there is any new data to be downloaded. I would suggest doing a similar thing for the bootstrap site.

Connecting to sql server 2008 database using C#
You connection string is wrong. It should be of this form if you use SQL Server Authentication: Server=myServerAddress;Database=myDataBase;User Id=myUsername; Password=myPassword; Where myServerAddress is the IP or host name of the computer running SQL Server. If it's your PC, localhost will probably work. myUsername and myPassword are the credentials of the user connecting to the server. If you use Trusted Connection,you connection string should be of this form: Server=myServerAddress;Database=myDataBase;Trusted_Connection=True; You can check more examples here: http://www.connectionstrings.com/sql-server/

Visual Basic Connecting to Database
performQuery function is faulty. It never closes the connection (Return dbDataReader happens before connection is being closed). On one hand - it's a good thing, because DataReader is useless without open connection. On the other - connection is opened as a private variable inside of a function so it goes out of scope when the function is returning and you never know when Garbage Collector will decide to collect it. It's always fun when this happens in the middle of Reader.Read.

Connecting to a database in Visual Studio
Yes, the database can be remotely hosted, I'have this working on my local machine with a remote MsSql database. Make sure the remote database server accepts connections from your IP. I'm pretty sure the MsSql Server Management Studio is only for MsSql, not MySql. The server name in my case is the IP for the remote MsSql database server, further you need the login and password for your database. But if you use your remote MySql, you don't need this tool. I have no experience with MySql, but it must be possible to use the database in your Visual Studio project with the correct "connectionstring". The connectionstring contains the type of the database, where it is located, login and pasword, etc. You can find the syntax of you connectionstring here: www.connectionstrings.com/mysql/

Effects of connecting to the database manually in vb.net
i come from both backgrounds. yes you can manually open database BUT you should specify the database you are using to make the best performance in your desktop application, for example: in access database (mdb files), you should open the database once in form_load, and use it all the time, then close it before exitting the application in form_closing (this is for better performance) while in SQL Server, you should open the database for each function then do your queries then close it after you finish.

Not seeing database from localhost but seeing it when connecting to server
GRANT USAGE is not what you want. According to the mysql documentation: USAGE Synonym for “no privileges” It is used at the global level with GRANT to modify account attributes such as resource limits or SSL characteristics without affecting existing account privileges. http://dev.mysql.com/doc/refman/5.1/en/grant.html You need to grant actual privileges to your "someuser" user for the database the user needs to see. For example, if you grant select privileges on the mysql.*: GRANT SELECT ON mysql.* TO someuser@localhost IDENTIFIED BY "somepassword"; FLUSH PRIVILEGES; Now, someuser connected from localhost will be able to see the mysql database when executing SHOW DATABASES; However, you might want to reserve the access to the mysql database for root only.

Connecting form to database errors
The error indicates the index Name is not found in the $_POST[] array. It is a PHP notice, and not a show-stopping error, but rather is intended to communicate that you are referencing a value which does not exist. If it is normal/expected that this value might be empty/null then the notice can be safely ignored. Beyond this problem, you should be sanitizing public values prior to referencing within the SQL statement, ie: $name = mysql_real_escape_string($_POST['Name']); $email = mysql_real_escape_string($_POST['Email']); A few other notes: In the call to mysql_connect() it is not necessary to wrap variables $host, $username or $password in quotes. The same is true with $db_name in call to mysql_select_db(). They are already strings as defined in the lines above and so this is excess

Error when connecting to database in unit test
This might not be an answer/solution to your actual problem, but a good tip in general. I strongly recommend not hitting the DB in every unit test, the same applies to the file system and other slow IO operations. Use a simple pattern like the Repository Pattern to abstract away the data access. You can then either implement a fake repository (i.e. backed by a List<T>) or use a mocking framework like moq to setup a mocked repository. By doing this, your tests will run completely in-memory and thus run much faster. You also don't need to care about connection strings and that you always have access to the database.

Using Heroku, connecting to database hosted on GoDaddy
Figured it out! The reason I couldn't connect to the DB on GoDaddy from Heroku is because the DB which I set up on GoDaddy didn't have the 'Allow Direct Access' option ticked. This option can only be enabled when you are creating a new database - once it's created it cannot be changed. The solution was to back up the database and create a new database with the 'Allow Direct Access' option selected and then use that database to connect to from the Heroku servers.
