ASP.NET資料庫連接字串集合

(一)常用串連:
1.使用SqlConnection對象:
public void SqlConnectionOpen()
{
SqlConnection conn= new SqlConnection();
conn.ConnectionString = "user id=sa;password=;initial catalog=northwind;datasource=localhost;connect Timeout=20";
conn.Open();
}

2.使用OleDbConnection對象:
public void OleDBConnectionOpen()
{
OleDBConnection conn = new OleDbconnection();
conn.ConnectionString="Provider=Microsoft.Jet.OLEDB.4.0;DataSource=C:\Customer.mdb";
conn.Open();
}

(二)其它:

1.ODBC串連Access本機資料庫
conGoodDay.Open("Driver={Microsoft Access Driver(*.mdb)};"+"Dbq=C:\a.mdb;"+
"Uid=Admin;"+"Pwd=;");

2.ODBC串連Access系統資料庫
conGoodDay.Open("Driver={Microsoft Access Driver(*.mdb)};"+"Dbq=C:\a.mdb;"+
"SystemDB=Admin;"+"Pwd=;");

3.ODBC串連Access系統資料庫
conGoodDay.Open("Driver={Microsoft Access Driver(*.mdb)};"+"Dbq=\\server\share\a.mdb;");

4.ODBC串連Excel系統資料庫
conGoodDay.Open("Driver={Microsoft Access Driver(*.xls)};"+"DriverId=790;"+
"Dbq=C:\a.xls;"+"DefaultDir=c:\somepath;");

5.ODBC串連Oracle系統資料庫
conGoodDay.Open("Driver={Microsoft ODBC for Oracle};"+"Server=OracleServer.world;"+
"Uid=Admin;"+"Pwd=password;");

6.ODBC串連Sql Servr
conGoodDay.Open("Driver={Sql Server};"+"Server=myServer;"+"Database=myDatabaseName;"
"Uid=Admin;"+"Pwd=password;");

7.ODBC串連Visual FoxPro
conGoodDay.Open("Driver={Microsoft Visual FoxPro Driver};"+
"SourceType=DBC;"+"SourceDB=c:a.dbc;"+"Exclusive=No;");
