数据库连接代码（SQLserver、Oracle、Access）

首先当然是SQL server 了，现在SQL server 的市场越来越大了

<%
function OpenConn(userid,pass,servername)
connstring="Provider=SQLOLEDB.1;Password=" & pass & ";Persist Security Info=True;User;Data Source=" & servername
set conn=server.createobject("ADODB.Connection")
conn.open connstring
set OpenConn=conn
end function
%>

说到连接数据库，当然不能忘记Oracle

<%
function OpenConn(userid,pass,servername)
connstring="Provider=MSDAORA.1;Password=" & pass &";User;Persist Security Info=True"
set conn=server.createobject("ADODB.Connection")
conn.open connstring
set OpenConn=conn
end function
%>

当然还有 Access,ODBC 等等，我就只把 连接字符串放到这里，自己慢慢研究吧

connstring="Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & server.mappath("test.mdb") &";Persist Security Info=False" //ACCESS
connstring="Provider=MSDASQL.1;Persist Security Info=False;Data Source=dsn"
