Microsoft SQL Server .NET Data Provider (System.Data.SqlClient)



The Microsoft SQL Server .NET Data Provide allows you to connect to a Microsoft
SQL Server 7.0, 2000, and 2005 databases.



For Microsoft SQL Server 6.5 or earlier, use the OLE DB .NET Data Provider with
the SQL Server OLE DB
Provider
(SQLOLEDB).



Using C#:



using System.Data.SqlClient; 
...
SqlConnection oSQLConn = new SqlConnection();
oSQLConn.ConnectionString = "Data Source=(local);" +
"Initial Catalog=myDatabaseName;" +
"Integrated Security=SSPI";
//Or
// "Server=(local);" +
// "Database=myDatabaseName;" +
// "Trusted_Connection=Yes";
oSQLConn.Open();
...
oSQLConn.Close();

// If you open the connection, then close the connection!
// Otherwise the connection does not go back into the connection pool.
// Note the SqlDataAdapter will open and close the connection for you
// when calling it's Fill or Update methods. However if the connection
// is already open, the SqlDataAdapter will leave it open.



Using VB.NET:



Imports System.Data.SqlClient 
...
Dim oSQLConn As SqlConnection = New SqlConnection()
oSQLConn.ConnectionString = _
"Data Source=(local);" & _
"Initial Catalog=myDatabaseName;" & _
"Integrated Security=SSPI"
oSQLConn.Open()



If connection to a remote server (via IP address):



oSQLConn.ConnectionString = _ 
"Network Library=DBMSSOCN;" & _
"Data Source=xxx.xxx.xxx.xxx,1433;" & _
"Initial Catalog=myDatabaseName;" & _
"User ID=myUsername;" & _
"Password=myPassword"
oSQLConn.Open()


Where:


- "Network Library=DBMSSOCN" tells SqlClient to use TCP/IP
Q238949


- xxx.xxx.xxx.xxx is an IP address of the remote SQL Server.


- 1433 is the port number for the remote SQL Server.
Q269882
and
Q287932


- You can also add "Encrypt=yes" for
encryption

MySQLDirect .NET Data Provider - From CoreLab (CoreLab.MySql)



MySQLDirect .NET is data provider to direct access to MySQL database server for
the Microsoft .NET Framework and .NET Compact Framework. It is completely based
on ActiveX Data Objects for the .NET Framework (ADO.NET) technology. ADO.NET provides
a rich set of components for creating distributed, data-sharing applications. It
is an integral part of the .NET Framework, providing access to relational data,
XML, and application data.



MySQLDirect .NET data provider can be used in the same way as the SQL Server .NET
or the OLE DB .NET Data Provider. Data provider can access MySQL server either using
native MySQL network protocol directly or through MySQL client library. It allows
to create lightweight and fast applications working with MySQL.




Using C#



using CoreLab.MySql; 
...
MySqlConnection oMySqlConn = new MySqlConnection();
oMySqlConn.ConnectionString = "User ID=myUsername;" +
"Password=myPassword;" +
"Host=localhost;" +
"Port=3306;" +
"Database=myDatabaseName;" +
"Direct=true;" +
"Protocol=TCP;" +
"Compress=false;" +
"Pooling=true;" +
"Min Pool Size=0;" +
"Max Pool Size=100;" +
"Connection Lifetime=0";
oMySqlConn.Open();



Using VB.NET



Imports CoreLab.MySql 
...
Dim oMySqlConn As MySqlConnection = New MySqlConnection()
oMySqlConn.ConnectionString = _
"User ID=myUsername;" & _
"Password=myPassword;" & _
"Host=localhost;" & _
"Port=3306;" & _
"Database=myDatabaseName;" & _
"Direct=true;" & _
"Protocol=TCP;" & _
"Compress=false;" & _
"Pooling=true;" & _
"Min Pool Size=0;" & _
"Max Pool Size=100;" & _
"Connection Lifetime=0"
oMySqlConn.Open()

Oracle .NET Data Provider - From Oracle (Oracle.DataAccess.Client)



The Oracle Data Provider for .NET (ODP.NET) features optimized data access to the
Oracle database from a .NET environment. ODP.NET allows developers to take advantage
of advanced Oracle database functionality, including Real Application Clusters,
XML DB, and advanced security. The data provider can be used from any .NET language,
including C# and Visual Basic .NET.




ODP.NET makes using Oracle from .NET more flexible, faster, and more stable. ODP.NET
includes many features not available from other .NET drivers, including Multiple
Active Result Sets (MARS), a native XML data type, the ability to bind array parameters,
and flexible LOB tuning. ODP.NET is designed for scalable enterprise Windows solutions
by providing full support for Unicode and local and distributed transactions. Distributed
transactions are supported using the Oracle Services for MTS.
