用自己的语言描述一下程序连接数据库的过程?
1.Access数据库的DSN-less连接方法:
set
adocon=Server.Createobject("adodb.connection")
adoconn.Open"Driver={Microsoft
Access Driver(*.mdb)};DBQ="& _
Server.MapPath("数据库所在路径")
2.Access OLE DB连接方法：
set
adocon=Server.Createobject("adodb.connection")
adocon.open"Provider=Microsoft.Jet.OLEDB.4.0;"&
_
"Data Source=" & Server.MapPath("数据库所在路径")
3.SQL
server连接方法：
set
adocon=server.createobject("adodb.recordset")
adocon.Open"Driver={SQL
Server};Server=(Local);UID=***;PWD=***;"&
_
"database=数据库名;"
4.SQL server OLE DB连接方法:
set
adocon=Server.Createobject("adodb.connection")
adocon.open"provider=SQLOLEDB.1;Data
Source=RITANT4;"& _
"user ID=***;Password=***;"& _
"inital
Catalog=数据库名"
5.Oracle 连接方法:
set
adocon=Server.Createobject("adodb.connection")
adocon.open"Driver={microsoft
odbc for oracle};server=oraclesever.world;uid=admin;pwd=pass;"
6.Oracle OLE DB 连接方法:
set
adocon=Server.Createobject("adodb.connection")
adocon.open"Provider=OraOLEDB.Oracle;data
source=dbname;user id=admin;password=pass;"
7.dBase
连接方法:
set
adocon=Server.Createobject("adodb.connection")
adocon.open"Driver={microsoft
dbase driver(*.dbf)};driverid=277;dbq=------------;"
8.mySQL
连接方法:
set
adocon=Server.Createobject("adodb.connection")
adocon.open"Driver={mysql};database=yourdatabase;
uid=username;pwd=yourpassword;option=16386;"
9.Visual Foxpro 连接方法:
set
adocon=Server.Createobject("adodb.connection")
adocon.open"Driver={microsoft
Visual Foxpro driver};sourcetype=DBC;sourceDB=*.dbc;Exclusive=No;"
10.MS text 连接方法:
set
adocon=Server.Createobject("adodb.connection")
adocon.open"Driver={microsoft
text driver(*.txt;
*.csv)};dbq=-----;"&_
"extensions=asc,csv,tab,txt;Persist
SecurityInfo=false;"
11.MS text OLE DB 连接方法:
set
adocon=Server.Createobject("adodb.connection")
adocon.open"Provider=microsof.jet.oledb.4.0;data
source=your_path;"&_
