Have you ever wanted to connect to a database without dealing with Oracle’s annoying reliance on the tnsnames.ora file?
The trick is to put the tnsnames information into the ODBC connection string directly, using the Data Source=… option.
The following (untested) code is VB, but the concept should work in any language that supports ODBC:
Dim TNS_INFO As String Dim cnxDB As New ADODB.Connection TNS_INFO = "(DESCRIPTION=" & _ "(ADDRESS_LIST=" & _ "(ADDRESS=(PROTOCOL=TCP)" & _ "(HOST=prodtst1.sdd.hp.com)" & _ "(PORT=1521)))" & _ "(CONNECT_DATA=(SID=prod_tst)" & _ "(SERVER=DEDICATED)))" cnxDB.ConnectionString = "Provider=OraOLEDB.Oracle;" & _ "Data Source=" & TNS_INFO & ";" & _ "user id=cressman;" & _ "password=mean2me" Debug.Print cnxDB.ConnectionString cnxDB.Open
