1. 相對(duì)與比較老的環(huán)境，建議使用第二個(gè)
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以上的機(jī)器，建議用此方法，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、附上一個(gè)經(jīng)常用的sqlserver與access通用的連接數(shù)據(jù)庫代碼
%
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數(shù)據(jù)庫，請(qǐng)認(rèn)真修改好以下數(shù)據(jù)庫選項(xiàng)
DataServer = "wwwjb51net" '數(shù)據(jù)庫服務(wù)器IP
DataUser = "jb51net" '訪問數(shù)據(jù)庫用戶名
DataBaseName = "jb51net" '數(shù)據(jù)庫名稱
DataBasePsw = "密碼" '訪問數(shù)據(jù)庫密碼
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 "數(shù)據(jù)庫連接出錯(cuò)，請(qǐng)檢查Conn.asp文件中的數(shù)據(jù)庫參數(shù)設(shè)置。":Response.End
%>
完整測(cè)試代碼
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 "用時(shí):"(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 "用時(shí):"(timer()-t)
%>
