Winsock TCP/IP
dbmsspxn Win32 SPX/IPX
dbmsvinn Win32 Banyan Vines

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.

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).

? Attach a database file on connect to a local SQL Server Express
instance:

- or
-
"Server=.\SQLExpress;AttachDbFilename=|DataDirectory|mydbfile.mdf;Database=dbname;Trusted_Connection=Yes;"

Why is the "Database" parameter needed? Answer: If the database

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.

? When to use SQL Native Client?
? .Net applications
Do not use the SQL Native Client. Use the .NET
Framework Data Provider for SQL Server (SqlConnection).
? COM applications, all other then .Net applications
Use the SQL
Native Client if you are accessing an SQL Server 2005 and need the new features
of SQL Server 2005 such as MARS, encryption, xml data type etc. Continue use
your current provider (OLE DB / ODBC through the MDAC package) if you are not
connecting to an SQL Server 2005 (that‘s quite obvious eh..) or if you are
connecting to an SQL Server 2005 but are not using any of the new SQL Server
2005 features.
For more details on the differences between MDAC and SQL
Native Client, read this msdn article >>
