I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Make you connection first

 ODBC Driver for Oracle

For the current Oracle ODBC Driver from Microsoft:

oConn.Open "Driver={Microsoft ODBC for Oracle};" & _
                   "Server=OracleServer.world;" & _
                   "Uid=myUsername;" & _
                   "Pwd=myPassword;"

For the older Oracle ODBC Driver from Microsoft:

oConn.Open "Driver={Microsoft ODBC Driver for Oracle};" & _
                   "ConnectString=OracleServer.world;" & _
                   "Uid=myUsername;" & _
                   "Pwd=myPassword;"


Or Build a DSN and connect
Dave_GreeneCommented:
Assuming you have a connection...

strQry = "Select  ITEM_NO  From  IC_ITEM_MST " & _
      " Where ITEM_NO Like '" & g_Pr_Item_No & "%' GROUP BY ITEM_NO "

  Set ADORS = New ADODB.Recordset
 
  ADORS.Open strQry, ADO_CONN, adOpenStatic, adLockBatchOptimistic
