ASP连接Access数据库的几种方法

  1. 相对与比较老的环境,建议使用第二个

  set dbconnection=Server.CREATEOBJECT("ADODB.CONNECTION")

  DBPath = Server.MapPath("customer.mdb")

  dbconnection.Open "driver={Microsoft Access Driver (*.mdb)};dbq=" & DBPath

  SQL="select * from auth where id='" & user_id &"'"

  SET uplist=dbconnection.EXECUTE(SQL)

  2.win2003以上的机器,建议用此方法,效率更高

  set dbconnection=Server.CreateObject("ADODB.Connection")

  DBPath = Server.MapPath("customer.mdb")

  dbconnection.Open "provider=microsoft.jet.oledb.4.0;data source="&dbpath

  SQL="select * from auth where id='" & user_id &"'"

  SET uplist=dbconnection.EXECUTE(SQL)

  3.

  DBPath = Server.MapPath("customer.mdb")

  set session("rs")=Server.CreateObject("ADODB.Recordset")

  ' rs=Server.CreateObject("ADODB.Recordset")

  connstr="provider=microsoft.jet.oledb.4.0;data source="&dbpath

  SQL="select * from auth where id='" & user_id &"'"

  session("rs").Open sql,connstr,1,3

  4. 建odbc源xxx

  set conn=server.createobject("Adodb.connection")

  conn.open "DSN=xxx;UID=;PWD=;Database=customer

  5、附上一个经常用的sqlserver与access通用的连接数据库代码

  <%

  Const DataBaseType=1

  If DataBaseType=0 then

  DBPath="/jb51/news.asp"

  SqlNowString = "Now()"

  ystr=true

  nstr=false

  suiji="rnd(id)"

  Else

  '如果是SQL数据库,请认真修改好以下数据库选项

  DataServer = "wwwjb51net" '数据库服务器IP

  DataUser = "jb51net" '访问数据库用户名

  DataBaseName = "jb51net" '数据库名称

  DataBasePsw = "密码" '访问数据库密码

  SqlNowString = "getdate()"

  ystr=1

  nstr=0

  suiji="newid()"

  End if

  On Error Resume Next

  If DataBaseType = 1 Then

  ConnStr="driver={SQL Server};server="&dataserver&";UID="&datauser&";PWD="&databasepsw&";Database="&databasename

  Else

  ConnStr = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & Server.MapPath(DBPath)

  End If

  Set conn = Server.CreateObject("ADODB.Connection")

  conn.open ConnStr

  If Err Then Err.Clear:Set conn = Nothing:Response.Write "数据库连接出错,请检查Conn.asp文件中的数据库参数设置。":Response.End

  %>

  完整测试代码

  Microsoft Access Driver

  <%

  db="1.mdb"

  dim conn,db

  dim connstr

  on error resume next

  connstr="DBQ="+server.mappath(""&db&"")+";DefaultDir=;DRIVER={Microsoft Access Driver (*.mdb)};"

  set conn=server.createobject("ADODB.CONNECTION")

  if err then

  err.clear

  else

  conn.open connstr

  end if

  t=timer()

  for i=0 to 1000

  Set Res=Conn.Execute("select (Select top 1 name from [aa] where id=1) as oldname,(Select top 1 name from [aa] where id=2) as newname from [aa]")

  aa=Res("oldname")

  bb=Res("newname")

  Res.close

  set Res=nothing

  next

  response.write "用时:"&(timer()-t)

  %>

  microsoft.jet.oledb.4.0

  <%

  db="1.mdb"

  dim conn,db

  dim connstr

  on error resume next

  connstr="provider=microsoft.jet.oledb.4.0;data source="+server.mappath(""&db&"")

  set conn=server.createobject("ADODB.CONNECTION")

  if err then

  err.clear

  else

  conn.open connstr

  end if

  t=timer()

  for i=0 to 1000

  Set Res=Conn.Execute("select (Select top 1 name from [aa] where id=1) as oldname,(Select top 1 name from [aa] where id=2) as newname from [aa]")

  aa=Res("oldname")

  bb=Res("newname")

  Res.close

  set Res=nothing

  next

  response.write "用时:"&(timer()-t)

  %>
