Basic connection string
web.config:
<configuration> <connectionStrings> <add name="SQLServerConnection" connectionString="Server=myServerName; Database=myDatabaseName;User Id=myUsername;Password=myPassword;" /> </connectionStrings> </configuration>
NOTE: Replace myServerName, myDatabaseName, myUsername, and myPassword with the correct details for your database.
How to create connection object in your code using the above connection string:
System.Data.SqlClient.SqlConnection conn = new System.Data.SqlClient(System.Configuration.ConfigurationManager.ConnectionStrings
["SQLServerConnection"].ConnectionString);
How to override default ASPNet Membership connection string
web.config:
<configuration> <connectionStrings> <remove name="LocalSQLServer" /> <add name="LocalSQLServer" connectionString="Server=myServerName;Database=myDatabaseName;User Id=myUsername;Password=myPassword;" /> </connectionStrings> </configuration>
NOTE: Replace myServerName, myDatabaseName, myUsername, and myPassword with the correct details for your database. For overriding the default ASPNet Membership connection string, it is important that the connection string name be left as "LocalSQLServer".
MySQL
MySQL connection string example:
NOTE: This example requires the following library from mysql.com to be referenced in your project (also ensure that 'CopyLocal' is set to 'True' on the reference):
http://dev.mysql.com/downloads/connector/net/
web.config:
<configuration> <connectionStrings> <add name="MySQLConnection" connectionString="Datasource=myServerName;Database=myDatabaseName;uid=myUsername;pwd=myPassword;" providerName="MySql.Data.MySqlClient"/> </connectionStrings> </configuration>
NOTE: Replace myServerName, myDatabaseName, myUsername, and myPassword with the correct details for your database.

Access Database Connection String Examples
Using DSN-less method
Conn.Open "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=d:\home\mysite.com\db\myfile.mdb;"
Using DSN
Conn.Open "MyDSN" Set Conn = CreateObject("ADODB.Connection") Conn.Open "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=d:\home\mysite.com\db\myfile.mdb;"
MySQL Connection String (ASP)
For newer versions of MySQL, use the below code.
Dim conDB Dim rs '--Set the connection Set conDB = CreateObject("ADODB.Connection") '--You may need to use OPTION=3 instead of 16834 conDB.Open "DRIVER=MySQL ODBC 5.1 Driver;SERVER=mysql10.hostek.com;OPTION=16834;USER=db_un;Password=db_pw;DATABASE=db_name" '--Set the recordset Set rs = CreateObject("ADODB.Recordset")
For older MySQL versions, you will want to use the below code.
Dim conDB Dim rs '--Set the connection Set conDB = CreateObject("ADODB.Connection") '--You may need to use OPTION=3 instead of 16834 conDB.Open "DRIVER=MySQL ODBC 3.51 Driver;SERVER=mysql10.hostek.com;OPTION=16834;USER=db_un;Password=db_pw;DATABASE=db_name" '--Set the recordset Set rs = CreateObject("ADODB.Recordset")
MSSQL Connection String (ASP)
ConnStr="DRIVER={SQLServer};SERVER=sql1.hostek.com;UID=db_username;PWD=db_password;DATABASE=db_name" Conn.open ConnStr
Replace the username, password, and database name with the information for your database.
