All SqlConnection connection string properties





This table shows all connection string properties for the ADO.NET SqlConnection
object. Most of the prope
rties 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

prope
rties

-
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 second
s) 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 conn
ection 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 Serve
r 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 c
reation 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 e
stablish 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, t
he 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 ano
ther value within the user value.




SQL Server 2005




SQL Native Client ODBC Driver



o


Standard security:

"Driver={SQL Native Client};Server=Aron1;Database=pubs;UID=sa;PWD=asdasd;"

o


Trusted connection:

"Driver={SQL Native Client};Server=Aron1;Database
=pubs;Trusted_Connection=yes;"

Equivalents

Integrated Security=SSPI equals Trusted_Connection=yes

o


Prompt for username and password:

oConn.Properties("Prompt") = adPromptAlways

oConn.Open "Driver={SQL Native Client};Server=Aron1;DataBase=pubs;"


o


Enablin
g 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 >>

o


Encrypt data sent over network:

"Driver={SQL Native
Client};Server=Aron1;Database=pubs;Trusted_Connection=yes;Encrypt=yes"

o


Attach a database file on connect to a local SQL Server E
xpress instance:

"Driver={SQL Native
Client};Server=.
\
SQLExpress;AttachDbFilename=c:

-

or

-

"Driver={SQL Native
Client};Server=.
\
SQLExpress;AttachDbFilename=|DataDirectory|mydbfile.mdf;Datab
ase=dbn
ame;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 attach
ed database as the default for the
connection).

(the package contains booth the ODBC driver and
the OLE DB
provider)

Using SQL Server 2005 Express? Don't miss the server name syntax:

\
mydbfile.mdf;Datab
ase=dbname;Trusted_Connection=Yes;"


-

or

-

"Provider=SQLNCLI;Server=.
\
SQLExpress;Attach
DbFilename=|DataDirectory|mydbfile.mdf;Da
tabase=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 Ser
ver does not reattach it (it uses the attached database as the default for the
connection).

Aron1;Initial Catalog=pubs;User Id=sa;Password=asdasd;"


-

or

-

"Server=Aron1;Database=pubs;User ID=sa;Password=asdasd;Trusted_Connection=False"


(both connection strings produces the same result)

o


Trusted Connection:

"Data Source=Aron1;Initial Catal
og=pubs;Integrated Security=SSPI;"


-

or

-

"Server=Aron1;Database=pubs;Trusted_Connection=True;"


(both connection strings produces the same result)

(use serverName
\
instanceName as Data Source to use an specifik SQLServer instance)

o


Connect via an IP

address:

"Data Source=190.190.200.100,1433;Network Library=DBMSSOCN;Initial Catalog=pubs;User
ID=sa;Password=asdasd;"

(DBMSSOCN=TCP/IP instead of Named Pipes, at the end of the Data Source is the port to use
(1433 is the default))

o


Enabling MARS (multipl
e active result sets):

"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 >>

o


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

\
SQLExpress;AttachDbFilename=c:
\
asd
\
qwe
\
mydbfile.mdf;Database=dbname;Datab
ase=d
bname;Trusted_Connection=Yes;"

or

-

"Server=.
\
SQLExpress;AttachDbFilename=|DataDirectory|mydbfile.mdf;Database=dbname;Tr
usted_Connection=Yes;"


(use |DataDirectory| when your database file resides in the data directory)


Why is the "Database" para
meter 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).

o


Using "User Instance" on a local SQL Server Express instance:

"Data Source=.
\
SQLExpress;integ
rated
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



o


C#:

using(SqlConnection connection = new SqlConnection("context connection=true"))

{


connection.Open();


// Use the connection

}

o


Visual Basic:

Using connection as new SqlConnection("context connection=true")


connection.Open()


' Use the connect
ion

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 Clien
t. 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, encryp
tion, 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,
