ASP VBScript

请各位老鸟给给建议！

错误类型：
Microsoft VBScript 编译器错误 (0x800A0401)
语句未结束
/MyWeb/a.asp, line 16, column 69
db = "provider=SQLOLEDB.1;Persist Security Info=False;Server="(local)";User ID="sa";Password="";Database="mytest""
--------------------------------------------------------------------^
源代码：
<%
dim conn
dim db
dim connstr

Set conn=Server.CreateObject("ADODB.connection")
db = "provider=SQLOLEDB.1;Persist Security Info=False;Server="(local)";User ID="sa";Password="";Database="mytest""
conn.Open db
sub CloseConn()
 conn.close
 set conn=nothing
end sub
%>

VBScript code

db = "provider=SQLOLEDB.1;Persist Security Info=False;Server=(local);User ID=sa;Password=;Database=mytest"

神马意思？能不能帮忙将详细一点？

很晕，楼主从哪看到的连接串写法？

网上找的+_+
