Most of the properties are also used in ADO. All properties and descriptions is from msdn.NoteUse ; to separate each property.If a name occurs more than once, the value from the last one in theconnectionstring will be used.If you are building your connectionstring in your app using values from userinput fields, make sure the user can't change the connectionstring by insertingan additional property with another value within the user value.∙ Access∙ ODBCo Standard Security:"Driver={Microsoft Access Driver(*.mdb)};Dbq=\somepath\mydb.mdb;Uid=Admin;Pwd=asdasd;"o Workgroup:"Driver={Microsoft Access Driver(*.mdb)};Dbq=\somepath\mydb.mdb;SystemDB=\somepath\mydb.mdw;","admin", ""∙ OLEDB, OleDbConnection (.NET)o Standard security:"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=\somepath\mydb.mdb;UserId=admin;Password=asdasd;"o Workgroup (system database):"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=\somepath\mydb.mdb;JetOLEDB:System Database=system.mdw;","admin", ""o With password:"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=\somepath\mydb.mdb;JetOLEDB:Database Password=MyDbPassword;","admin", ""∙ Oracle∙ ODBCo New version:"Driver={Microsoft ODBC forOracle};Server=OracleServer.world;Uid=Username;Pwd=asdasd;"o Old version:"Driver={Microsoft ODBC Driver forOracle};ConnectString=OracleServer.world;Uid=myUsername;Pwd=myPassword;"∙ OLEDB, OleDbConnection (.NET)o Standard security:"Provider=msdaora;Data Source=MyOracleDB;UserId=UserName;Password=asdasd;"This one's from Microsoft, the following are from Oracleo Standard Security:"Provider=OraOLEDB.Oracle;Data Source=MyOracleDB;UserId=Username;Password=asdasd;"o Trusted Connection:"Provider=OraOLEDB.Oracle;Data Source=MyOracleDB;OSAuthent=1;"OracleConnection (.NET)o Standard:"Data Source=Oracle8i;Integrated Security=yes";This one works only with Oracle 8i release 3 or latero Declare the OracleConnection:C#:using System.Data.OracleClient;OracleConnection oOracleConn = new OracleConnection();oOracleConn.ConnectionString = "my connectionstring";oOracleConn.Open();:Imports System.Data.OracleClientDim oOracleConn As OracleConnection = New OracleConnection()oOracleConn.ConnectionString = "my connectionstring"oOracleConn.Open()∙ Data Shapeo MS Data Shape:"Provider=MSDataShape.1;Persist Security Info=False;DataProvider=MSDAORA;Data Source=orac;user id=username;password=mypw"∙ MySQL∙ ODBCo Local database:"Driver={mySQL};Server=mySrvName;Option=16834;Database=mydatabase;"o Remote database:"Driver={mySQL};Server=;Port=3306;Option=131072;Stmt=;Database=my-database;Uid=username;Pwd=password;"∙ OLEDB, OleDbConnection (.NET)o Standard:"Provider=MySQLProv;Data Source=mydb;User Id=UserName;Password=asdasd;"∙ MySqlConnection (.NET)o EID:"Data Source=server;Database=mydb;User ID=username;Password=pwd;CommandLogging=false"This one is used with eInfoDesigns dbProvider, an add-on to .NET o Declare the MySqlConnection:C#:using EID.MySqlClient;MySqlConnection oMySqlConn = new MySqlConnection();oMySqlConn.ConnectionString = "my connectionstring";oMySqlConn.Open();:Imports EID.MySqlClientDim oMySqlConn As MySqlConnection = New MySqlConnection()oMySqlConn.ConnectionString = "my connectionstring"oMySqlConn.Open()∙ IBM DB2∙ OLEDB, OleDbConnection (.NET) from mso TCP/IP:"Provider=DB2OLEDB;Network Transport Library=TCPIP;NetworkAddress=XXX.XXX.XXX.XXX;Initial Catalog=MyCtlg;PackageCollection=MyPkgCol;Default Schema=Schema;User ID=MyUser;Password=MyPW"o APPC:"Provider=DB2OLEDB;APPC Local LU Alias=MyAlias;APPC Remote LUAlias=MyRemote;Initial Catalog=MyCtlg;Package Collection=MyPkgCol;DefaultSchema=Schema;User ID=MyUser;Password=MyPW"∙ Sybase∙ ODBCo Standard:"Driver={SYBASE SYSTEM 11};Srvr=Aron1;Uid=username;Pwd=password;"o Intersolv 3.10:"Driver={INTERSOLV 3.10 32-BITSybase};Srvr=Aron1;Uid=username;Pwd=password;"∙ Informix∙ ODBCo Informix 3.30:"Dsn='';Driver={INFORMIX 3.30 32BIT};Host=hostname;Server=myserver;Service=service-name;Protocol=olsoctcp;Database=mydb;UID=username;PWD=myPwdo Informix-CLI 2.5:"Driver={Informix-CLI 2.5 (32Bit)};Server=myserver;Database=mydb;Uid=username;Pwd=myPwd"∙ DSN∙ ODBCo DSN:"DSN=myDsn;Uid=username;Pwd=;"o File DSN:"FILEDSN=c:\myData.dsn;Uid=username;Pwd=;"∙ Excel∙ ODBCo Standard:"Driver={Microsoft Excel Driver(*.xls)};DriverId=790;Dbq=C:\MyExcel.xls;DefaultDir=c:\mypath;"∙ OLE DBo Standard:"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\MyExcel.xls;ExtendedProperties=Excel 8.0;HDR=Yes;""HDR=Yes;" indicates that the first row contains columnnames, notdata∙ DBF / FoxPro∙ ODBCo standard:"Driver={Microsoft dBASE Driver (*.dbf)};DriverID=277;Dbq=c:\mydbpath;"∙ OLEDB, OleDbConnection (.NET)o standard:"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=c:\folder;ExtendedProperties=dBASE IV;User ID=Admin;Password="∙ Pervasive∙ ODBCo Standard:"Driver={Pervasive ODBC Client Interface};ServerName=srvname;dbq=@dbname" ∙ UDL∙ UDLo UDL:"File Name=c:\myDataLink.udl;"。
