SQL Server Set your custom connection string values
This is a compiled connection strings reference list on how to connect to SQL Server.
ODBC

Standard Security

複製代碼 代碼如下:Driver={SQL Server};Server=myServerAddress;Database=myDataBase;Uid=myUsername;Pwd=myPassword;

Trusted connection

複製代碼 代碼如下:Driver={SQL Server};Server=myServerAddress;Database=myDataBase;Trusted_Connection=Yes;

Prompt for username and password
This one is a bit tricky. First you need to set the connection object's Prompt property to adPromptAlways. Then use the connection string to connect to the database. 複製代碼 代碼如下:oConn.Properties("Prompt") = adPromptAlways

Driver={SQL Server};Server=myServerAddress;Database=myDataBase;

OLE DB, OleDbConnection (.NET)
Standard Security 複製代碼 代碼如下:Provider=sqloledb;Data Source=myServerAddress;Initial Catalog=myDataBase;User Id=myUsername;Password=myPassword;

Trusted connection

複製代碼 代碼如下:Provider=sqloledb;Data Source=myServerAddress;Initial Catalog=myDataBase;Integrated Security=SSPI;

Use serverName\instanceName as Data Source to use a specific SQL Server instance. Please note that the multiple SQL Server instances feature is available only from SQL Server version 2000 and not in any previous versions.

Prompt for username and password
This one is a bit tricky. First set the connection object's Provider property to "sqloledb". Thereafter set the connection object's Prompt property to adPromptAlways. Then use the connection string to connect to the database. 複製代碼 代碼如下:oConn.Provider = "sqloledb"
oConn.Properties("Prompt") = adPromptAlways

Data Source=myServerAddress;Initial Catalog=myDataBase;

Connect via an IP address

複製代碼 代碼如下:Provider=sqloledb;Data Source=190.190.200.100,1433;Network Library=DBMSSOCN;Initial Catalog=myDataBase;User ID=myUsername;Password=myPassword;

DBMSSOCN=TCP/IP. This is how to use TCP/IP instead of Named Pipes. At the end of the Data Source is the port to use. 1433 is the default port for SQL Server.

SqlConnection (.NET)

Standard Security

複製代碼 代碼如下:Data Source=myServerAddress;Initial Catalog=myDataBase;User Id=myUsername;Password=myPassword;

Standard Security alternative syntax
This connection string produce the same result as the previous one. The reason to include it is to point out that some connection string keywords have many equivalents. 複製代碼 代碼如下:Server=myServerAddress;Database=myDataBase;User ID=myUsername;Password=myPassword;Trusted_Connection=False;

Specifying packet size

複製代碼 代碼如下:Server=myServerAddress;Database=myDataBase;User ID=myUsername;Password=myPassword;Trusted_Connection=False;Packet Size=4096;

By default, the Microsoft .NET Framework Data Provider for SQL Server sets the network packet size to 8192 bytes. This might however not be optimal, try to set this value to 4096 instead.
The default value of 8192 might cause errors as well ("Failed to reserve contiguous memory"), check this out >>

Data Shape

MS Data Shape

複製代碼 代碼如下:Provider=MSDataShape;Data Provider=SQLOLEDB;Data Source=myServerAddress;Initial Catalog=myDataBase;User ID=myUsername;Password=myPassword;
