.NET中各种数据库连接大全(转载)

• SQL Server
  • ODBC
    
    
    • Standard Security:
      "Driver={SQL Server};Server=Aron1;Database=pubs;Uid=sa;Pwd=asdasd;"
    • Trusted connection:
      "Driver={SQL Server};Server=Aron1;Database=pubs;Trusted_Connection=yes;"
    • Prompt for username and password:
      oConn.Properties("Prompt") = adPromptAlways
      oConn.Open "Driver={SQL Server};Server=Aron1;DataBase=pubs;"
  • OLEDB, OleDbConnection (.NET)
    
    
    • Standard Security:
      "Provider=sqloledb;Data Source=Aron1;Initial Catalog=pubs;User Id=sa;Password=asdasd;"
    • Trusted Connection:
      "Provider=sqloledb;Data Source=Aron1;Initial Catalog=pubs;Integrated Security=SSPI;"

(use serverName\instanceName as Data Source to use an specifik SQLServer instance, only SQLServer2000)

• Prompt for username and password:
  oConn.Provider = "sqloledb"
  oConn.Properties("Prompt") = adPromptAlways
  oConn.Open "Data Source=Aron1;Initial Catalog=pubs;"
• Connect via an IP address:
  "Provider=sqloledb;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))

• SqlConnection (.NET)
  
  
  • Standard Security:
    "Data Source=Aron1;Initial Catalog=pubs;User Id=sa;Password=asdasd;"
  • Trusted Connection:
    "Data Source=Aron1;Initial Catalog=pubs;Integrated Security=SSPI;"

(use serverName\instanceName as Data Source to use an specifik SQLServer instance, only SQLServer2000)

• 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))

• Declare the SqlConnection:

C#:
using System.Data.SqlClient;

Dim oSQLConn As SqlConnection = New SqlConnection()
oSQLConn.ConnectionString="my connectionstring"
oSQLConn.Open()

  • OLEDB, OleDbConnection (.NET)
    
    
    • Standard security:
      "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=\somepath\mydb.mdb;User Id=admin;Password=asdasd;"

    • With password:
      "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=\somepath\mydb.mdb;Jet OLEDB:Database Password=MyDbPassword;","admin", ""
• Oracle
  • ODBC
    
    
    • New version:

    • Old version:
      "Driver={Microsoft ODBC Driver for Oracle};ConnectString=OracleServer.world;Uid=myUsername;Pwd=myPassword;"
  • OLEDB, OleDbConnection (.NET)
    
    
    • Standard security:
      "Provider=msdaora;Data Source=MyOracleDB;User Id=UserName;Password=asdasd;"

This one's from Microsoft, the following are from Oracle

• Standard Security:
