QTP连接Oracle

QTP通过ADO访问Oracle数据库的一个例子：

Dim rs,sq,pkey
set conn=createobject("adodb.connection")
set rs=createobject("adodb.recordset")

' 需要安装Oracle客户端
conn.open "Provider=OraOLEDB.Oracle.1;Persist Security Info=False;User ID=scott;Data Source=orcl;Password=orcl;Extended Properties=;Host=192.168.1.188;Port=1521;Service Name=orcl;"

sql="SELECT * FROM TAB"
rs.open sql,conn
rs.MoveFirst
Do While rs.Eof<>true
Msgbox rs.Fields(0)
rs.MoveNext
Loop
rs.close
set rs=nothing
conn.close
set conn=nothing
