SQL Server 2005数据库连接串

SQL Native Client ODBC Driver

标准连接:

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

信任连接:

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

提示用户名和密码:

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"

通过网络发送数据时加密:

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

连接SQL实例时附加一个数据文件:

"Driver={SQL Native Client};Server=.\SQLExpress;AttachDbFilename=c:\asd\qwe\mydbfile.mdf;Database=dbname;Trusted_Connection=Yes;"
- 或 -
"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)



SQL Native Client OLE DB Provider

Standard security:

"Provider=SQLNCLI;Server=Aron1;Database=pubs;UID=sa;PWD=asdasd;"

Trusted connection:

"Provider=SQLNCLI;Server=Aron1;Database=pubs;Trusted_Connection=yes;"

Prompt for username and password:

oConn.Properties("Prompt") = adPromptAlways
oConn.Open "Provider=SQLNCLI;Server=Aron1;DataBase=pubs;"

Enabling MARS (multiple active result sets):

"Provider=SQLNCLI;Server=Aron1;Database=pubs;Trusted_Connection=yes;MarsConn=yes"

Encrypt data sent over network:

"Provider=SQLNCLI;Server=Aron1;Database=pubs;Trusted_Connection=yes;Encrypt=yes"

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

"Provider=SQLNCLI;Server=.\SQLExpress;AttachDbFilename=c:\asd\qwe\mydbfile.mdf;Database=dbname;Trusted_Connection=Yes;"
- or -
"Provider=SQLNCLI;Server=.\SQLExpress;AttachDbFilename=|DataDirectory|mydbfile.mdf;Database=dbname;Trusted_Connection=Yes;"
(use |DataDirectory| when your database file resides in the data directory)



SqlConnection (.NET)

Standard Security:

"Data Source=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)

Trusted Connection:

"Data Source=Aron1;Initial Catalog=pubs;Integrated Security=SSPI;"
- or -
"Server=Aron1;Database=pubs;Trusted_Connection=True;"
(both connection strings produces the same result)


Connect via an IP address:
"Data Source=190.190.200.100,1433;Network Library=DBMSSOCN;Initial Catalog=pubs;User ID=sa;Password=asdasd;"

Enabling MARS (multiple active result sets):

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

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

"Server=.\SQLExpress;AttachDbFilename=c:\asd\qwe\mydbfile.mdf;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)

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

"Data Source=.\SQLExpress;integrated security=true;attachdbfilename=|DataDirectory|\mydb.mdf;user instance=true;"


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
