I am trying to connect to Oracle via Excel 2013 and MS Query Oracle ODBC. I am using the same username, password ans service name that is working just fine from the same pc with PL/SQL Developer, but when I try to connect I get an error message:

ORA-12560: TNS:protocol adapter error - Driver's SQLSetConnectAttr failed

WHat is causing this? In my c:\oracle directory I have a subdirectory orant11 (version 11?).

My sqlnet.ora file in the network\admin-folder looks like this:
# SQLNET.ORA Network Configuration File: c:\oracle\orant11\network\admin\sqlnet.ora
# Generated by Oracle configuration tools.

NAMES.DEFAULT_DOMAIN = xxx.no

SQLNET.AUTHENTICATION_SERVICES= (NONE)

NAMES.DIRECTORY_PATH= (TNSNAMES, ONAMES, HOSTNAME)

Open in new window


and the tnsnames.ora file in the same folder looks like this (ip and service names changed for security reasons):

# TNSNAMES.ORA Network Configuration File: c:\oracle\orant11\network\admin\tnsnames.ora
# Generated by Oracle configuration tools.
MYAPP.XXX.NO = 
  (DESCRIPTION= 
    (ADDRESS_LIST= 
      (ADDRESS= 
        (PROTOCOL=TCP) 
        (Host=99.9.249.99) 
        (Port=1541) 
      ) 
    ) 
    (CONNECT_DATA= 
      (SERVICE_NAME=MYAPP) 
    ) 
  ) 

Open in new window


Can you please help?

Thx!

I have found a different way to connect that worked fine right away:

1. Goto Data-pane in Excel.
2. Click on 'From other data sources'
3. Click From wizard for database connection' (just above Microsoft Query)
4. Select 'Other/advanced'
5. Click 'Next'
6. Select 'Oracle provider for OLE DB
7. Input the datasource ip:port/sid
8. Input username and password
9. Click test connection
10. SUCCESS!

However, the method I outlined above doesn't seem to allow me to use queries, it only transfers entire tables. Which can be useful at times, but I am typically using tables with hundreds of thousands of rows, and hence it is not ideal. So the best would be to get the ODBC connection to work.

oracle client contains different dlls and methods for connecting to a database

restart the oracle client installer
check custom install
and add the odbc/ole db provider options

that should fix the excel problem

sql developer connects with oci component
excel with ole db/odbc component
