- How to define which network protocol to use
Example:
"Provider=sqloledb;Data Source=190.190.200.100,1433;Network Library=DBMSSOCN;Initial Catalog=pubs;User ID=sa;Password=asdasd;"
| Name | Network library | | dbnmpntw | Win32 Named Pipes | | dbmssocn | Win32 Winsock TCP/IP | | dbmsspxn | Win32 SPX/IPX | | dbmsvinn | Win32 Banyan Vines | | dbmsrpcn | Win32 Multi-Protocol (Windows RPC) |
Important note!
When connecting through the SQLOLEDB provider use the syntax Network Library=dbmssocn
and when connecting through MSDASQL provider use the syntax Network=dbmssocn
- All SqlConnection connection string properties
This table shows all connection string properties for the ADO.NET SqlConnection object. Most of the properties are also used in ADO. All properties and descriptions is from msdn.
| Name | Default | Description |
|---|
| application Name | | The name of the application, or '.Net SqlClient Data Provider' if no application name is provided. | AttachDBFilename
-or-
extended properties
-or-
Initial File Name | | The name of the primary file, including the full path name, of an attachable database. The database name must be specified with the keyword 'database'. | Connect Timeout
-or-
Connection Timeout | 15 | The length of time (in seconds) to wait for a connection to the server before terminating the attempt and generating an error. | | Connection Lifetime | 0 | When a connection is returned to the pool, its creation time is compared with the current time, and the connection is destroyed if that time span (in seconds) exceeds the value specified by connection lifetime. Useful in clustered configurations to force load balancing between a running server and a server just brought on-line. | | Connection Reset | 'true' | Determines whether the database connection is reset when being removed from the pool. Setting to 'false' avoids making an additional server round-trip when obtaining a connection, but the programmer must be aware that the connection state is not being reset. | | Current Language | | The SQL Server Language record name. | Data Source
-or-
Server
-or-
Address
-or-
Addr
-or-
Network Address | | The name or network address of the instance of SQL Server to which to connect. | | Enlist | 'true' | When true, the pooler automatically enlists the connection in the creation thread's current transaction context. | Initial Catalog
-or-
Database | | The name of the database. | Integrated Security
-or-
Trusted_Connection | 'false' | Whether the connection is to be a secure connection or not. Recognized values are 'true', 'false', and 'sspi', which is equivalent to 'true'. | | Max Pool Size | 100 | The maximum number of connections allowed in the pool. | | Min Pool Size | 0 | The minimum number of connections allowed in the pool. | Network Library
-or-
Net | 'dbmssocn' | The network library used to establish a connection to an instance of SQL Server. Supported values include dbnmpntw (Named Pipes), dbmsrpcn (Multiprotocol), dbmsadsn (Apple Talk), dbmsgnet (VIA), dbmsipcn (Shared Memory) and dbmsspxn (IPX/SPX), and dbmssocn (TCP/IP).
The corresponding network DLL must be installed on the system to which you connect. If you do not specify a network and you use a local server (for example, "." or "(local)"), shared memory is used. | | Packet Size | 8192 | Size in bytes of the network packets used to communicate with an instance of SQL Server. | Password
-or-
Pwd | | The password for the SQL Server account logging on. | | Persist Security Info | 'false' | When set to 'false', security-sensitive information, such as the password, is not returned as part of the connection if the connection is open or has ever been in an open state. Resetting the connection string resets all connection string values including the password. | | Pooling | 'true' | When true, the SQLConnection object is drawn from the appropriate pool, or if necessary, is created and added to the appropriate pool. | | User ID | | The SQL Server login account. | | Workstation ID | the local computer name | The name of the workstation connecting to SQL Server. |
Note
Use ; to separate each property.
If a name occurs more than once, the value from the last one in the connection string will be used.
If you are building your connection string in your app using values from user input fields, make sure the user can't change the connection string by inserting an additional property with another value within the user value.
SQL Server 2005 - SQL Native Client ODBC Driver
- Standard security:

- Trusted connection:

Integrated Security=SSPI equals Trusted_Connection=yes - Prompt for username and password:
oConn.Properties("Prompt") = adPromptAlways
oConn.Open "Driver={SQL Native Client};Server=Aron1;DataBase=pubs;"
- Enabling MARS (multiple active result sets):
"Driver={SQL Native Client};Server=Aron1;Database=pubs;Trusted_Connection=yes;MARS_Connection=yes" Equivalents
MultipleActiveResultSets=true equals MARS_Connection=yes
Using MARS with SQL Native Client, by Chris Lee >> - Encrypt data sent over network:
"Driver={SQL Native Client};Server=Aron1;Database=pubs;Trusted_Connection=yes;Encrypt=yes"
- Attach a database file on connect to a local SQL Server Express instance:
"Driver={SQL Native Client};Server=./SQLExpress;AttachDbFilename=c:/asd/qwe/mydbfile.mdf;Database=dbname;Trusted_Connection=Yes;"
- or -
"Driver={SQL Native Client};Server=./SQLExpress;AttachDbFilename=|DataDirectory|mydbfile.mdf;Database=dbname;Trusted_Connection=Yes;"
(use |DataDirectory| when your database file resides in the data directory)
Why is the "Database" parameter needed? Answer: If the database was previously attached, SQL Server does not reattach it (it uses the attached database as the default for the connection). Download the SQL Native Client here >> (the package contains booth the ODBC driver and the OLE DB provider) Using SQL Server 2005 Express? Don't miss the server name syntax: SERVERNAME/SQLEXPRESS (Substitute "SERVERNAME" with the name of the computer)

"Server=Aron1;Database=pubs;Trusted_Connection=True;MultipleActiveResultSets=true" Note! Use ADO.NET 2.0 for MARS functionality. MARS is not supported in ADO.NET 1.0 nor ADO.NET 1.1
Streamline your Data Connections by Moving to MARS, by Laurence Moroney, DevX.com >> - Attach a database file on connect to a local SQL Server Express instance:
"Server=./SQLExpress;AttachDbFilename=c:/asd/qwe/mydbfile.mdf;Database=dbname;Database=dbname;Trusted_Connection=Yes;"
- or -
"Server=./SQLExpress;AttachDbFilename=|DataDirectory|mydbfile.mdf;Database=dbname;Trusted_Connection=Yes;"
(use |DataDirectory| when your database file resides in the data directory) Why is the "Database" parameter needed? Answer: If the database was previously attached, SQL Server does not reattach it (it uses the attached database as the default for the connection). - Using "User Instance" on a local SQL Server Express instance:
"Data Source=./SQLExpress;integrated security=true;attachdbfilename=|DataDirectory|/mydb.mdf;user instance=true;" The "User Instance" functionality creates a new SQL Server instance on the fly during connect. This works only on a local SQL Server 2005 instance and only when connecting using windows authentication over local named pipes. The purpose is to be able to create a full rights SQL Server instance to a user with limited administrative rights on the computer. To enable the functionality: sp_configure 'user instances enabled','1' (0 to disable) Using SQL Server 2005 Express? Don't miss the server name syntax: SERVERNAME/SQLEXPRESS (Substitute "SERVERNAME" with the name of the computer)
- Context Connection - connecting to "self" from within your CLR stored prodedure/function
- C#:
using(SqlConnection connection = new SqlConnection("context connection=true"))
{
connection.Open();
// Use the connection
}
- Visual Basic:
Using connection as new SqlConnection("context connection=true")
connection.Open()
' Use the connection
End Using
The context connection lets you execute Transact-SQL statements in the same context (connection) that your code was invoked in the first place.
