Hi People.

i have installed Oracle OLEDB Provider but i am unable to connect to the Oracle 9i DB.

My Page Looks like this

<%
     Set objConn = Server.CreateObject("ADODB.Connection")
     
     objConn.Open "Provider=OraOLEDB.Oracle.1;Persist Security Info=False;User ID=scott;Password=tiger;Data Source=ned;"  
     
     Set objRs = objConn.Execute("SELECT * FROM EMPLOYEE")

     Response.Write "<table border=1 cellpadding=4>"
     Response.Write "<tr>"

     For I = 0 To objRS.Fields.Count - 1
       Response.Write "<td><b>" & objRS(I).Name & "</b></td>"
     Next

     Response.Write "</tr>"

     Do While Not objRS.EOF
       Response.Write "<tr>"

       For I = 0 To objRS.Fields.Count - 1
         Response.Write "<td>" & objRS(I) & "</td>"
       Next

       Response.Write "</tr>"

       objRS.MoveNext
     Loop

     Response.Write "</table>"

     objRs.Close
     objConn.Close
   %>

Error i get is :
Error Type:
ADODB.Connection (0x800A0E7A)
Provider cannot be found. It may not be properly installed.

Do you have the orracle TNS names entry set up properly?  Looking at the code it would be called 'ned'?

Try changing the provider from OraOLEDB.Oracle.1 to MSDAORA

Make sure IUSER_computername has permissions for the folder where the Oracle provider is installed.  
To help troubleshoot this you could also set IIS to run under your id or convert your asp script to vbs and run from the command prompt.

BTW, MSDAORA has limitations such as you can't acess clobs and blobs.

Here's what I mean about the vbs script...

Create test.vbs with the following code then exucte it at the command prompt...

Set rs = CreateObject("ADODB.Recordset")
cnstr = "Provider=OraOLEDB.Oracle.1;Persist Security Info=False;User ID=scott;Password=tiger;Data Source=ned;"  rs.Open "select sysdate from dual", cnstr, 3, 3
WScript.echo rs("sysdate")
rs.Close
Set rs = Nothing

I use Oracle 9i and the code below works. (This assumes that Oracle is installed in the default  port. If not, then the port # must be included in the connection string)


Try something like this:


StrConnect="Provider=MSDAORA.1;Data Source=database_scheme;User Id=user_name;PASSWORD=database_password;"


set  objConnection=server.createobject("adodb.connection")
 objConnection.open StrConnect


varSQL = "SELECT DISTINCT USER_ID FROM EMPLOYEE"

set rstemp = objConnection.Execute(varSQL)  


Do While NOT temp_record_set .EOF
 
   Response.Write "<td><b>" &  rstemp (0)  & "</b></td>"
  rstemp.MoveNext
Loop

   rstemp.close
   set rstemp=nothing
         
  objConnection.close
   set objConnection=nothing
