1. 相对与比较老的环境，建议使用第二个
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
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.
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
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)
%>
