ASP连接Access数据库的几种方法

投稿:mdxy-dxy

学习程序很大一部分需要与数据库连接操作,这里简单的整理下asp连接access的一些代码,方便需要的朋友

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)
%>
